That's not disrespectful, it's simply true. The Tally Ho project has gone above and beyond to beautify the elements of the boat at every step of the way
No disrespect taken. You like what you see and enjoy the most. I’m the same but become more attached to this channel because Leo and the guys and girl show all the content 96% of the time unlike other channels who just put a camera up and leave it on Timelapse.
Never ceases to amaze me just how beautiful a ship Tally Ho is. Well crafted, all lines true and fair. Simply stunning. A credit to all who worked on her and especially to Leo who brought it all together.
As the adventure continues, unlike big yachts afloat even at Port Townsend, the viewers (fans) have such special access to Tally Ho's interior below as well as on-deck. Wherever a segment is filmed, we enjoy having seen the craftsmanship that created the area, the railing, deck, every square inch. So this new perspective -in the water-lets the adventure continue and is very enjoyable whatever is being done. I hope the series can continue, featuring all aspect of on-board, and at sea life. Thanks for a super feature, can't wait until the next time, prop or transmission.
How refreshing for a leader (and Leo has shown himself to be a great leader) be so open and candid about problems encountered. Makes for great problem- solving and ultimately much more respect for the leader.
As I see it, the only real choice is to change the gear box to what it should be. Changing the prop is just short changing the whole system to what it's not supposed to be.
The good thing is that Leo now has verified performance data on the current config. That is, hull speed for a given prop size/pitch, rpm and gear ratio. It’s clearly hit near max hull speed at a shade over 8 knots so the current prop is working well and with lower gearing might be ideal. Notwithstanding that larger (current) props are typically more efficient and Tally Ho’s prop aperture has been made to accomodate the larger prop, the prop engineers will no doubt provide optimum combination advice. Me - I’d swap the box if the calcs come out favourably for the alternative ratio if available.
In my uneducated opinion, changing the gearbox to what was originally planned sounds like the best course of action. Although lifting out the cockpit already might feel sour even if it is designed to come out.
Also, if the whole system was designed for 2.5:1, this prop issue might not the only issue. Better to fix the root cause and avoid other unintended consequences, that could cost more in the long run. You’ve come too far to “cheap out” now. My dear old dad taught me that the definition of Boat is “a hole in the water, surrounded by wood, into which you pour money.” Edited to add: she’s a beautiful boat, and you and your team have done a wonderful job on her!
I agree. The appeture in the rudder is also made for the larger propeller so i seems like the best choice to keep it. I would also assume that the larger prop would work better when using it to generate power when sailing, which the hybrid drivetrain allows for.
What a wonderful outcome to this seven-year saga - TALLY HO is finally moving like a real boat, and her keel is getting to know the shoals of the Pacific Northwest. Thanks for taking us all along, Leo.
since we dont know all the specific considerations we cant really make an informed opion, but taking everyting we know into consideration, changing the gearbox apears to be the best. especialy since everything else was disigned around that. and im pretty sure almost everyone watching and following wouldn't mind waiting a bit longer for her to sail, we are here for this beatifull boat and these amazing videos, not because we want to see her sail as soon as possible but because we want to see her fully comleted and in the best shape she will ever be in.
The hydrodynamics of the hull look great from looking at the bow wave, wake, and smooth trail behind the hull. Those drone shots are great! Very interesting findings on the engine, gearbox, and prop matching. Finding and recreating Tally Ho was an excellent choice. At first I was disappointed in the stubby appearance, but Tally Ho is no slouch in the water and the amount of sail she can hoist is amazing.
Yes , doesn't she slip through the water beautifully ! I too was noticing how full the shape is at the beam going aft and yet she is really light in the bum - releasing with little drag and as you say - no wake astern . Beautiful higher efficient hull for such a heavy vessel . All the wake seems to come from the bows and it's small and short wavelength. I can't wait to see her really sailing in a breeze.
I'm quite late to the Tally Ho project, just catching up now. Thank you so much Leo and team for the journey you've taken us on. I have a suggestion with catching the drone on a ship. It works AFAIK on all drones but at least does on a few DJI drones I've used. Once the person catching the drone out of the air has a grip on it, rotate the drone 90 degrees (so that the top is facing horizontally). The drone will pick up this pitch and cut off the motors immediately so it wouldn't full throttle into a wall/the floor etc. Takes a little bit of practice but in my opinion it's better than it going full throttle again to try get away from your hand grabbing it that it doesn't understand. Hope this helps.
It's good you already ran aground once. Got that out of the way. Changing the gearbox to be as designed sounds reasonable, as long as the electrical motor/generator side still matches.
The "Proposed Propulsion LayOut" at 27:30 mins of EP87 shows the beautiful electrical and propulsion AND recharging system for Tally Ho. I'm guessing the 1/2:57 ratio PRM500 engine tranny needs the engine at 2800 RPM driving the 20KW Gen/Motors at 1100 RPM to optimize charging the 6 main batteries and THEN
Sorry - I've been following Leo since he arrived in Oregon and this is my first comment. I posted without finishing my comment. What I am implying as a retired Professional Engineer they optimized the charging with the 1:2.57 ratio, and THEN optimized the propeller at that engine/generators output and Leo's desire for a smaller opening in the rudder... I also think they could lift the engine from the deck beams enough to switch out the tranny AND the pulleys/belt driving the generators/motors - keeping the prop as is.
Congratulations on the grounding. Got that out of the way nicely (and softly)! Into the logbook it goes. I vote to change the gearbox. Thank You for sharing your wonderful life with us.
I liked the comment, "There are two kinds of sailors, those who run aground and liars". A truly great platform showing off team work, multiple skills and a little humour.
Brilliant, you have built, unquestionably the most beautiful yacht, a pinnacle of craftsmanship, historic or modern. Speaking of modern, you spark craftsmen everywhere to aim high, very high. My father had a 40" wooden Sparkman Stevens for Great Lakes and Newport to Bermuda racing.in the 50s and sixties and I kinda remember her, a little leaky after a rock grounding in the Tobermory, Canada. He then traded her in for an innovative plastic Rhodes Bounty 40 at the time, for a couple of Transatlantic Races in the sixties. I was probably born in the focs'le. In the late seventies, I was a schoolboy and fortunate enough to attend the Pt. Townsend Boat Shows. It was gratifying to know these special boats would be preserved. After a career in professional multihull racing and as a yacht captain, I am restoring a 1965 20' Lyman, the workhorse of the Great Lakes. My favorite deliveries are on nice light wood epoxy boats. You feel a connection with the water. Like Dad I built my 55' cat out of plastic ( she had prop problems too for a little while) 1/2 round striping on a male plug with core cell and epoxy because it was a little faster to build at the time, I wish I had gone with wood and epoxy. I may build a smaller one yet, you guys are inspiring me big time. Bravo, congratulations to all of you master craftsmen, and thank you.
Been watching for many years. It’s so satisfying to see Tally Ho out on the water doing what she does best. Especially with the crew that worked so hard to get her where she is today!
Tally Ho, 2027! I'm going to put money on her winning. I'm also going to attempt to buy the failed capstan top casting if possible. Windy Hill Foundry is selling it to compensate the volunteers that cast the new top cap to replace her solidly rusted old top cap. If I get it I'll make a giant clock out of it. It will be the only one in the world!
Not being a boat builder but having many many projects I hope you stick with the prop and change the gearbox to the 2.5:1 it was supposed to have because that's the design and it was done for a reason. I think if you stick with your current gearbox you'll regret it but my opinion doesn't matter and you guys are the experts so I'll just leave it at that. Love seeing Tally Ho under her own power!
my favorite line in the whole thing you may ask?.... well, that's easy - it was in response to a query from Leo as to just one of the details that someone might be able to clarify among the thousands that Leo shares in every episode, and the answer from Patty was?..... "we wrote it down somewhere"!!!
Sorry about your prop problems, but it is so lovely to see Tally Ho alive, in her natural environment. She certainly is a beautiful yacht and I cannot wait to see her under sail. Thank you Leo, and crew. Well done indeed!
I think it’s better to change the gear box to the originals design and specification. It will be a good ‘dry’ run of hauling out the power unit so to give a solid understanding as to what is possible say when your at sea.
16:32 before deciding, consider which strategy will work better for generating electricity while under sail an light winds. Extra drag near hull speed might improve downwind stability, might it not?
Hi Leo and crew great to see you all enjoying Tally Ho in the water . I don’t think you should change the gearbox the root cause is to do with the propellor which can be easily solved . Reduce the pitch of the 4 blades and the diameter of the propeller overall to increase the rpm to max rpm recommend . Talk with any prop specialist they will know exactly what to do . Other than that I would have varioprop send me a 3 blade propellor with the same diameter and 1 inch less pitch which will increase your rpm to 2600+ rpm . Hope you get sorted soon and this was of some help to you guys .
I’ve got to say that I watch a lot of boat building videos but once they go in the water I kind of lose interest. It’s not because I don’t like sailing, it’s more that the video format tends to become very boring (closeups and close quarters content) you have completely overcome that with your many angles, shots and camera angles. I bet it’s an absolute pain in the arse to film and to edit out but it honestly makes the world of difference. I was genuinely worried when you said you’d be launching that I would lose interest. Keep up the fantastic work!
Something which has always impressed me about you crew is the ease which you cut into things, like cutting the deck for those vents. The first time I noticed this was back when Leo was working on the keel and that near-priceless purple wood.
Measure three times, cut once. You just make sure the cut is in the right place. At times it is hard to see holes put into large sections of lumber that were selected carefully to be continuous pieces.
I remember watching Leo cut the keel (with a chainsaw, as I recall it) and just wincing thinking he'd make a drastic error. Boy, was I wrong! But like you I'm amazed how freely they cut holes and trim all their fine woodwork.
@@Grandroborox - I mean, of course they’re triple-checking every measurement and are even using jigs, as in this example, to guide them. But there’s just something intense to me about committing to a cut like that. For instance, the decking he went into was so lovely and had already had so much time put into it, with the boards lined-up just so. Needs must and all, and an unlikely error can be remedied surely, but it’s still admirable to me for whatever reason. It’s something like carving the ear on an otherwise finished marble statue: the tension isn’t so much about the risk of a mistake but how consequential such a mistake would be. For some, even if the risk of it is minimal, the enormity of consequence may stay their hand or at least give them pause.
So good to see that beautiful machine out doing what it was build to do. The drone shots really add to the beauty of the event. I'm sure you'll get the prop issues resolved in time. Looking forward to seeing her under sail.
Used to live in Poulsbo and Keyport, had a 13 ft boat with a 9.5 hp motor. Went from Bremerton all around Bainbridge Is. And up to Port Townsend. Brings back memories watching. Boat was all wood but not quite to the specs of Tally Ho. Still……. Memories.
When deciding on the prop or gearbox: keep in mind on what the electric sytem runs best on and also the regenarative system runs best. If those two run best on the current prop it may be smarter to change the gearbox ratio! Great work!!!
Since the prop design/thinking led the decision on the gear box, it would seem best to change out the gears. Plus, it's less expensive. Great video. Loved the grounding section - been there. Cheers
I LOVE Tally Ho and its crew! One of the most beautiful boats I have ever seen. And built especially well!!!!! Looking forward to future adventures! Keep up the killer work guys. May FAVORITE UA-cam channel!
Love it Leo “so now we wait” English understatement! if you never make a mistake you are not pushing hard enough! A tad too much tech try swinging a piece of string with a tallow ended plumb bob. Kind regards Tim
Yeah Rusty! Kind of like building a house. You walk the rooms on the ground and they seem tiny. Lay it out on the deck and they get a bit bigger. Put up the walls and they shrink again. That's where both design and construction experience come in, which keep you from freaking out at each stage. Also looks bigger below decks than above, I imagine. OK! Enough of this motor crap; let's hoist some sails!
Right? She looked huge up on the hard, and tiny now that she's wet. Reminded me right away of the old verse "“Oh God, thy sea is so great and my boat is so small.”
I would have to agree with what seems the general sentiment about changing out the gear box. Think of it as a great chance to learn and show more about the mechanical aspect of the boat!
The big thing would be can you find a gearbox that fits easily (relative thing......). Changed mine and all I needed was to lower the engine on the mounts about 7mm and I fitted a new extended coupling. Would also want a commercially rated gearbox.. .. Great video and what a lovely boat she is.
This was a most interesting video! It's slightly alarming that such a small amount of either pitch in the prop or ratio in the gearbox can create such a drop in performance. However, like most things mechanical, it is not beyond the wit of man to correct it, as you stated Leo. The only other thought which occurs to me is that if the engine is allowed to rotate at the stated speed of 2800, will the generator and other systems be detrimentally affected? What about the various pumps and so on...will they run at that increased speed without burning out, melting the impellers, or running the bearings? She looks beautiful under power, and creates remarkably little wash at both the bow and the transom. You're absolutely right about ventilation. Added to all you said, there is also the air being used for combustion in the engine, which will also be noticeable when it is not there. An old engineer who worked for Mirrlees once said to me "a diesel requires just four things: lots of clean air and clean diesel, clean oil and a job to do" and I have always remembered this when doing work on diesels, even though this was over fifty years ago. I don't think things have changed much. Bon Voyage...
Tally Ho sails beautifully! Congratulations and the video is great -as usual. You pamper us. - If the gearbox does not affect the output of the electric drives/charger, go for it. - It may have happened that you wanted to calibrate the ecosounder/depth gage. Otherwise, it is a fantastic coincidence you had 3 cameras on the exact spot: filming from the coast + George on the drone confirming he got it + camera on the boat + Nick in the bow (and one can see there is a mudbank from amidships....). Still that is the only way to really calibrate the depth gauge so well done ... and you add some drama and you avoid discussion on the comments of whether you did it on purpose or not.
Change the gearbox, optimise the system to original design spec. You and the team have produced a beautiful boat, looking foward to seeing her under sail.
For anyone looking for the historical videos of gearbox identification, here they are: Engine selection: @27:30 it shows a "PRM500 1:2.57" and the 22" 4 blade feathering prop with a 17" pitch on the drawing ua-cam.com/video/xohxmwPfctg/v-deo.htmlsi=9p1Pcjva_etADNCL Engine unboxing: @16:04 Leo states the expected 1:2.5 ratio ua-cam.com/video/c4UMMQFgmVI/v-deo.htmlsi=2oAkWTdAM3OJ1eco
Great Video! It is really splendid to see Tally Ho cutting the water. You mentioned that there was a miscommunication since you designed all the system for a 2.5:1 gearbox but the engine came with a 2:1 gearbox and you are considering both alternatives: changing gearbox or changing Propeller. I must assume then that changing the gearbox will have no impact in the electric motors' power/consumption and charging output? PS: Nice story: I was sailing in a small sailing boat owned by the French navy with two French Naval officers in South England coast. I had the pleasure to see how we ran aground in River Dart, pretty close to the Britannia Royal Naval College in a low tide, and see how all the 3 roawing boats manned by british naval officer cadets passed beside the boat in their afternoon exercise. Being myself spaniard, every time I've seen my french friends in the last 20 years, I do not miss the opportunity to remind them that the french navy ran aground and 100 english "officers to be" that made a rowing parade to a heeling french navy sailboat.🤣
Changing the gearbox to the original specs may well increase the electrical output of the generators when they are being driven by the propellor (using excess sail power during favorable wind conditions).
Such great filmmaking to really draw out the suspense on the departure, knowing that we all know what's coming from the title/intro, then pretty quickly and matter-of-factly get to the point on the return when it actually happens XD
Commercial drone pilot here. Have you considered a launch cradle on a stick? Hand catching leaves your assistant's fingers vulnerable to prop stroke injuries.
The future looks bright indeed. Say, Leo, you might reconsider salt water flush for the heads. Seawater in the lines, and in the bowl, makes an awful stink as organisms grow. A fresh water flush system is usually easy to set up, and need only be used in harbor and locally. Not a matter of timely evacuation of the holding tank, it's the hoses and the bowl that go foul. On any offshore cruise salt water flush is fine, as waste goes overboard. The organism/stink factor also applies to seawater use in the galley, to save fresh. That pump will also stink if not flushed with fresh. Perhaps your system already takes all of this into account. Cheers and tally ho!
Leo has a Betamarine 85hp diesel. He needs to get the rpms up to 2700-2800 for max power/efficiency (rated at 85hp @ 3000 rpm). The prop-shaft and propeller are likely maxed out at 1000-1100 rpm since he commented they were near hull-speed. Sounds like a gearbox switch is indicated to get the diesel matched to the propeller better. The electric motors will also charge the batteries better in elec.-mode with a better gear-ratio.
Like I mentioned a while back also. Your slot flow cuts on the haul and rudder maybe not wide or tall enough. Basically causing vortices around the prop starving the propeller of flow water.
don't fret about it! I have personally unintentionally discovered about 90% of the sea floor around Florida in my ketch! I'm the local hydrographic surveyor's favorite sailor!
😱 My heart almost stopped as I read the title of this video (although I know that beautiful and sturdy built Tally Ho has a thick board as a sacrificial keel underneath the led keel. 2) To hear about the gear box problem made me kind of sad. I hope that everything will go well and that the correct gearbox will go onto Tally Ho's engine. 3) What Leo said at the end of the video is, amongst a lot of other things, what makes him so great and so successful: "That's not the end of the world. Just got to make the decision and get the work done!" So definitely no procrastination in sight on this channel! 😁 ;-) As always: Thanks a lot for making teaching explaining recording editing uploading and sharing. Best regards, luck and especially health to all involved people.
The propeller is already the correct propeller and was sized to work well to generate electricity under sail. As such the gearbox ought to be replaced.
Hey Leo, First time long time..2017. Just had to say how beautiful Tally Ho is , her lines, water cascading off the bows waterline, etc.. Watching her go through the water on this episode was amazing. The feeling you must have at the tiller must be overwhelming thinking back to that dollar. I built my first too and remember that pride. Well done, perhaps we will pass each other at sea some day.
Watched every video from the beginning as they have been posted. Only commented a few times but liked almost all of them (I forget occasionally). The current issue is a no brainer. The entire design and build has been superb from the beginning so there is no reason to change now. If the mistake on the gearbox was in the order then you must suffer the cost and replace it with the designed one. If the order was correct and the supplier got it wrong then they should replace it at zero cost. Either way the solution lies with the gearbox as originally designed. To change the prop would be deserting the original design in 2 ways, gearbox and prop which is not acceptable. Good luck Leo, I'm sure you will make the right decision. !👌👍👍
bloody well proper, time to walk the plank laddy my boy who ever grabbed 2:1 inventory and the installer not cross checking gearing ratio needing to be 2:1.5 Cancel Reply
Stick with your original design-plan for the correct gearbox ratio mate. IM-biased-HO, it's unlikely Leo's 'ordering mistake' because everything about this project has been such smooth sailing; well almost. Anyway I say, "Leo olde boy, go with your original best intention." P.S. Crew & boat together have awakened & uplifted many souls to the timeless great craft of wooden boat building. Thank you & congratulations Leo, crew & extended family. Cheers from Sydney, AU.🤠
Amateur engineer here: change the gearbox to the original spec. A smaller prop would likely be less efficient for low speed propulsion. Also, the original (larger) prop will do better than a smaller one when using it to drive the generators via boat motion. I love the idea of using the "excess" power available from the sails in favorable winds. Once hull speed has been reached, you want to be able to harvest as much electrical energy as possible-the original prop should be better for that.
“Trust but Verify” is the phrase that comes to mind in this situation that you found yourself in. No matter the choice you make the results will be top quality! Like everything that you and your team do!
@@ColinWatters looked to me to be on the output shaft side of the gearbox and separately controlled, which would mean that the electric drive and sprockets are matched to the current prop.
When it comes to changing the prop or the gear box, you would have to consider the electric drive and also what is best for charging the battery's under sail. You would want to make the change that will complement these extra systems.
Hi Leo, shit happens... I whould suggest you to change the gearbox for 2,5:1. As far as I know, always slower running props are desired because of more efficiency. So it should be short term and long term cheaper. I hope any professionals can confirm that. Regards!
As I understand it for a for displacement hull a relatively large diameter propeller turning slowly is more efficient than a small one turning fast so yes its better go for the lower ratio gearbox . (might not apply to a planing hull )
@@henrymorgan3982 "Communication error" sounds an awful lot like someone requested the wrong box. These things happen on big projects, just gotta grit your teeth and rectify them.
@@henrymorgan3982 The manufacturer has probably taken responsibility for the miscommunication, or at least offered to swap the gearbox for a reduced fee, hence Leo saying that it's cheaper to replace the gearbox, but it takes more work. It's not exactly the manufacturer's fault that the gearbox ratio was spotted at the time it was in the water, that could have been spotted much easier (but it's also understandable that nobody checked this particular aspect).
@@isfiyiywafibc6qaiiiiiiiiii570a large bronze feathering prop is an expensive bit of kit, there's not much economy of scale in that sort of thing, while all sorts of machines use a gearbox, without looking it up I could well believe it is simply cheaper to buy a new gearbox than a new prop.
I agree you did the right thing getting the boat in the water. Project management techniques will tell you exactly the same thing, try and move forward to see if any of these sorts of issues are highlighted. Keep up your positive attitude, love it.
It's ok if she runs aground, because of how she's built. Not much damage can happen. It's when you're stuck and the water goes down that things get risky. Also, she has a long time before she's out of sea trials. No voyage any time soon.
Just think of it as Tally Ho remembering that time back in the 50s when a grounding ripped her whole side open. She knows that boats always run aground, and she wanted to get it over with easy, so that the coral reef doesn't happen again. Boats might be inanimate objects, but they still have feelings. I believe that anyway. I've had too many motorcycles, planes, and boats with personalities to think otherwise.
I see some true joy on the crews faces - even when challenges arose. Wishing you all the best and looking forward to watching you work on other projects while the gear box and propeller issue gets sorted. Really looking forward to the capstan install!!
I did this off the coast of Kodiak once. Middle of the night we rested on the rocks for a few hours. We also turned off all the lights and hid through the night and floated away as the tide (25 foot tides in Kodiak) lifted us off and let us return to port. Not embarrassing to tell the story but so glad the coast guard didn't see us.
Don't forget to review the motor/alternator side of your drive system when deciding whether to switch out the gearbox or the propeller. It's likely the unit shipped with that gearbox because it is matched to the motor/alternator side of the system.
The gearbox doesn't matter to accessories that drive off the crankshaft, like Tally Ho's. Driving stuff off of the gearbox, like PTO shafts driving hydraulic pumps and such, then the gear ratios would matter a lot. You can check that out on the Fabrats video building a wrecker. They drove the hydraulic winches off of the transfer case's low range gears and they could pull a house... but only at about one foot per hour! 🙂
Go back and watch the second half of episode 115 where they uncrate the engine. Leo pulls the cover on the hybrid drive system and talks about it. It looks a lot like the timing belt on a DOHC V6. The PRM hydraulic gearbox that gets bolted to the diesel output can be supplied with different gear ratios. But that gear ratio combined with the tooth ratio of the drive belt pulley ratio will have to align with the speed range of the twin 10kW motors. So I think that he is stuck with the gearbox ratio that was supplied and will have to match the propeller to the hybrid motor and not the other way around. But for sure it will be fun to see how they resolve it.
I would opt for changing the gearbox rather than replacing the prop. That way you don't have to haul the boat out of the water, which is also an added cost. Tally Ho Leo & Crew! 👍👍
I'll bet the gearbox is designed to have many "common parts" both externally and internally, It might be possible to swap the two gears that currently provide the incorrect ratio with two other gear wheels that mesh together perfectly using all the stub axles and bearings etc internally, to produce the required ratio. It's just a few teeth less on the little driving cog and a few more teeth on the transmitting cog after all,. Externally, the casing and all other parts are quite likely to be identical. A few hours swapping the gears and you're good to go 😁
might be even less of a hasle if the gearbox is just one single unit they can replace, then it would only be a problem of dicoupling and hauling out the old one and reinstalling the new one, but if the space around it wont tollerate that it might indeed be posible to swap gears, if the gearbox has enough internal room to allow for a bigger gear
First of all - a beautiful boat! Great job Leo and the whole team! Regarding the problem of gear ratio mismatch, it seems to me that it is worth changing the gearbox and saving the calculated data. An enlarged propeller is violence against the system. And, when sailing, it will give more resistance. It's up to you to decide. Good luck and thanks!
I hope he does make that choice, but you may have noticed, he gave a heart-like to one commenter who made the case for a prop change. That troubled me a bit.
Well, for her first grounding, at least it was in soft mud! Seems like you need a nav screen in the cockpit to be able to monitor her depth.... Cheers from Oregon, Philip
Well that's me covered then because I ran aground last night. Went to drop the hook and it would not run out. Then I remembered I had just had some work done on the rode and I guess the guy that did it didn't stow the chain neatly enough and it got lodge inside the hawser. So had to put her on the beach in a flat calm falling tide for the night. Consequently, I couldn't set the anchor properly and when the tide rose at 2.00 this morning we went off on a little wander amongst the other boats. Managed to re-set the hook but then found that when the tide returned mid morning, I couldn't get of the sand and while it had been like a mill pond last night, not so this morning with a stiff onshore breeze and a considerable chop driving us father into the shore as the water rose.. Eventually managed to physically heave in enough chain to enable me to get into deep enough water where I could use the engine to rip it out of the sand and motor out into deeper water where I was able to eventually get the anchor onto the deck. Sailing single handed has it disadvantages as well as its benefits lol.
No disrespect to anyone else, as I enjoy many boat building channels, but Tally Ho is unquestionably the most beautiful of all the UA-cam sailboats.
That's not disrespectful, it's simply true. The Tally Ho project has gone above and beyond to beautify the elements of the boat at every step of the way

By getting her first scratches, tally ho has transitioned from being a restorated museum piece to a real, living, functioning boat. Well done!
My opinion too!
Tally Ho knew that it was going to happen. She wanted to get it over with on a nice smooth bottom, rather than on a coral reef in the South Pacific!
I do this with new motorcycle leathers. I find it’s good luck to roll around on the ground before using them to get that out of the way
Like in the movie Galaxy Quest.

As I see it, the only real choice is to change the gear box to what it should be. Changing the prop is just short changing the whole system to what it's not supposed to be.
Agreed.
Ditto
The good thing is that Leo now has verified performance data on the current config. That is, hull speed for a given prop size/pitch, rpm and gear ratio. It’s clearly hit near max hull speed at a shade over 8 knots so the current prop is working well and with lower gearing might be ideal. Notwithstanding that larger (current) props are typically more efficient and Tally Ho’s prop aperture has been made to accomodate the larger prop, the prop engineers will no doubt provide optimum combination advice. Me - I’d swap the box if the calcs come out favourably for the alternative ratio if available.
Box.
Shouldn't it require replacing a gear and not the entire box?
Now that you've run aground you're qualified to be a ferry boat captain for Washinton State Ferry system.
Easy fundraising opportunity. I'd pay a lot more to bop over to Bainbridge on Tally Ho than on a boring old WSF.
In my uneducated opinion, changing the gearbox to what was originally planned sounds like the best course of action. Although lifting out the cockpit already might feel sour even if it is designed to come out.
agree with you.
I'm guessing that they can change the GB without lifting the cockpit. It might be a bit tight, but it will be a good test of the engine room design.
Also, if the whole system was designed for 2.5:1, this prop issue might not the only issue. Better to fix the root cause and avoid other unintended consequences, that could cost more in the long run. You’ve come too far to “cheap out” now.
My dear old dad taught me that the definition of Boat is “a hole in the water, surrounded by wood, into which you pour money.”
Edited to add: she’s a beautiful boat, and you and your team have done a wonderful job on her!
I agree. The appeture in the rudder is also made for the larger propeller so i seems like the best choice to keep it.
I would also assume that the larger prop would work better when using it to generate power when sailing, which the hybrid drivetrain allows for.
@@meldert would there also be a loss of propulsion if it was switched to a smaller prop, even if it were spun at a higher speed?
It makes me smile to my bones to watch Tally Ho in the water. And in the silt. xxx
What a wonderful outcome to this seven-year saga - TALLY HO is finally moving like a real boat, and her keel is getting to know the shoals of the Pacific Northwest. Thanks for taking us all along, Leo.
since we dont know all the specific considerations we cant really make an informed opion, but taking everyting we know into consideration, changing the gearbox apears to be the best. especialy since everything else was disigned around that. and im pretty sure almost everyone watching and following wouldn't mind waiting a bit longer for her to sail, we are here for this beatifull boat and these amazing videos, not because we want to see her sail as soon as possible but because we want to see her fully comleted and in the best shape she will ever be in.
The hydrodynamics of the hull look great from looking at the bow wave, wake, and smooth trail behind the hull. Those drone shots are great! Very interesting findings on the engine, gearbox, and prop matching. Finding and recreating Tally Ho was an excellent choice. At first I was disappointed in the stubby appearance, but Tally Ho is no slouch in the water and the amount of sail she can hoist is amazing.
Yes , doesn't she slip through the water beautifully ! I too was noticing how full the shape is at the beam going aft and yet she is really light in the bum - releasing with little drag and as you say - no wake astern . Beautiful higher efficient hull for such a heavy vessel . All the wake seems to come from the bows and it's small and short wavelength.
I can't wait to see her really sailing in a breeze.
I'm quite late to the Tally Ho project, just catching up now. Thank you so much Leo and team for the journey you've taken us on.
I have a suggestion with catching the drone on a ship. It works AFAIK on all drones but at least does on a few DJI drones I've used.
Once the person catching the drone out of the air has a grip on it, rotate the drone 90 degrees (so that the top is facing horizontally). The drone will pick up this pitch and cut off the motors immediately so it wouldn't full throttle into a wall/the floor etc.
Takes a little bit of practice but in my opinion it's better than it going full throttle again to try get away from your hand grabbing it that it doesn't understand.
Hope this helps.
It's good you already ran aground once. Got that out of the way.
Changing the gearbox to be as designed sounds reasonable, as long as the electrical motor/generator side still matches.
All that work and all those skills have truly created a beautiful boat.
So great to see this project coming to a finish, but I will miss the wood working!
So Bountiful
Incredibly beautiful!
Agreed
Not to worry. She's a boat and constant repairs are just part of the game! 🙂
@@knlazar08 Absolutely true.
The "Proposed Propulsion LayOut" at 27:30 mins of EP87 shows the beautiful electrical and propulsion AND recharging system for Tally Ho. I'm guessing the 1/2:57 ratio PRM500 engine tranny needs the engine at 2800 RPM driving the 20KW Gen/Motors at 1100 RPM to optimize charging the 6 main batteries and THEN
Sorry - I've been following Leo since he arrived in Oregon and this is my first comment. I posted without finishing my comment.
What I am implying as a retired Professional Engineer they optimized the charging with the 1:2.57 ratio, and THEN optimized the propeller at that engine/generators output and Leo's desire for a smaller opening in the rudder... I also think they could lift the engine from the deck beams enough to switch out the tranny AND the pulleys/belt driving the generators/motors - keeping the prop as is.
Congratulations on the grounding.
Got that out of the way nicely (and softly)! Into the logbook it goes.
I vote to change the gearbox.
Thank You for sharing your wonderful life with us.
I liked the comment, "There are two kinds of sailors, those who run aground and liars".
A truly great platform showing off team work, multiple skills and a little humour.
Brilliant, you have built, unquestionably the most beautiful yacht, a pinnacle of craftsmanship, historic or modern. Speaking of modern, you spark craftsmen everywhere to aim high, very high.
My father had a 40" wooden Sparkman Stevens for Great Lakes and Newport to Bermuda racing.in the 50s and sixties and I kinda remember her, a little leaky after a rock grounding in the Tobermory, Canada. He then traded her in for an innovative plastic Rhodes Bounty 40 at the time, for a couple of Transatlantic Races in the sixties. I was probably born in the focs'le.
In the late seventies, I was a schoolboy and fortunate enough to attend the Pt. Townsend Boat Shows. It was gratifying to know these special boats would be preserved.
After a career in professional multihull racing and as a yacht captain, I am restoring a 1965 20' Lyman, the workhorse of the Great Lakes.
My favorite deliveries are on nice light wood epoxy boats. You feel a connection with the water. Like Dad I built my 55' cat out of plastic ( she had prop problems too for a little while) 1/2 round striping on a male plug with core cell and epoxy because it was a little faster to build at the time, I wish I had gone with wood and epoxy. I may build a smaller one yet, you guys are inspiring me big time.
Bravo, congratulations to all of you master craftsmen, and thank you.
Been watching for many years. It’s so satisfying to see Tally Ho out on the water doing what she does best. Especially with the crew that worked so hard to get her where she is today!
Tally Ho moves through the water so beautifully. What a great boat!
Did you notice her wake? Even at 8 knots she wants to go faster. I can feel it right through the screen!
Tally Ho, 2027!
I'm going to put money on her winning. I'm also going to attempt to buy the failed capstan top casting if possible. Windy Hill Foundry is selling it to compensate the volunteers that cast the new top cap to replace her solidly rusted old top cap. If I get it I'll make a giant clock out of it. It will be the only one in the world!
@@knlazar08 Should make a nice clock that will never crack :) We tested it for cracking with a lot of bullets :)
Not being a boat builder but having many many projects I hope you stick with the prop and change the gearbox to the 2.5:1 it was supposed to have because that's the design and it was done for a reason. I think if you stick with your current gearbox you'll regret it but my opinion doesn't matter and you guys are the experts so I'll just leave it at that. Love seeing Tally Ho under her own power!
my favorite line in the whole thing you may ask?.... well, that's easy - it was in response to a query from Leo as to just one of the details that someone might be able to clarify among the thousands that Leo shares in every episode, and the answer from Patty was?..... "we wrote it down somewhere"!!!
Sorry about your prop problems, but it is so lovely to see Tally Ho alive, in her natural environment. She certainly is a beautiful yacht and I cannot wait to see her under sail. Thank you Leo, and crew. Well done indeed!
I think it’s better to change the gear box to the originals design and specification. It will be a good ‘dry’ run of hauling out the power unit so to give a solid understanding as to what is possible say when your at sea.
That’s probably the best idea, and when you have it disconnected from the prop shaft install a spare toothed drive belt.
And if you designed the prop for that ratio, it'd be nice to stick to the design and not have any other unforeseen issues.
16:32 before deciding, consider which strategy will work better for generating electricity while under sail an light winds. Extra drag near hull speed might improve downwind stability, might it not?
True, but agonizing do over.
Which option gives Tally Ho more power and potential control (ie: safety) of the boat and crew? I would presume the larger prop but I'm a novice.
Hi Leo and crew great to see you all enjoying Tally Ho in the water . I don’t think you should change the gearbox the root cause is to do with the propellor which can be easily solved . Reduce the pitch of the 4 blades and the diameter of the propeller overall to increase the rpm to max rpm recommend . Talk with any prop specialist they will know exactly what to do . Other than that I would have varioprop send me a 3 blade propellor with the same diameter and 1 inch less pitch which will increase your rpm to 2600+ rpm . Hope you get sorted soon and this was of some help to you guys .
I’ve got to say that I watch a lot of boat building videos but once they go in the water I kind of lose interest. It’s not because I don’t like sailing, it’s more that the video format tends to become very boring (closeups and close quarters content) you have completely overcome that with your many angles, shots and camera angles. I bet it’s an absolute pain in the arse to film and to edit out but it honestly makes the world of difference. I was genuinely worried when you said you’d be launching that I would lose interest. Keep up the fantastic work!
Something which has always impressed me about you crew is the ease which you cut into things, like cutting the deck for those vents. The first time I noticed this was back when Leo was working on the keel and that near-priceless purple wood.
Measure three times, cut once. You just make sure the cut is in the right place. At times it is hard to see holes put into large sections of lumber that were selected carefully to be continuous pieces.
I remember watching Leo cut the keel (with a chainsaw, as I recall it) and just wincing thinking he'd make a drastic error. Boy, was I wrong! But like you I'm amazed how freely they cut holes and trim all their fine woodwork.
It might seem freely done but it's not. Triple measuring and deliberating isn't so captivating to watch so we don't get to.
@@Grandroborox - I mean, of course they’re triple-checking every measurement and are even using jigs, as in this example, to guide them. But there’s just something intense to me about committing to a cut like that. For instance, the decking he went into was so lovely and had already had so much time put into it, with the boards lined-up just so. Needs must and all, and an unlikely error can be remedied surely, but it’s still admirable to me for whatever reason. It’s something like carving the ear on an otherwise finished marble statue: the tension isn’t so much about the risk of a mistake but how consequential such a mistake would be. For some, even if the risk of it is minimal, the enormity of consequence may stay their hand or at least give them pause.
So good to see that beautiful machine out doing what it was build to do. The drone shots really add to the beauty of the event. I'm sure you'll get the prop issues resolved in time. Looking forward to seeing her under sail.
Used to live in Poulsbo and Keyport, had a 13 ft boat with a 9.5 hp motor. Went from Bremerton all around Bainbridge Is. And up to Port Townsend. Brings back memories watching. Boat was all wood but not quite to the specs of Tally Ho. Still……. Memories.
When deciding on the prop or gearbox: keep in mind on what the electric sytem runs best on and also the regenarative system runs best. If those two run best on the current prop it may be smarter to change the gearbox ratio! Great work!!!
The drone and camera footage is spectacular......including the NPR Tiny Desk Concert shirt! DD
its great to see the whole team enjoying the fruits of their hard work
Since the prop design/thinking led the decision on the gear box, it would seem best to change out the gears. Plus, it's less expensive. Great video. Loved the grounding section - been there. Cheers
Can't imagine the joy you felt at that moment, but you sure looked pleased! What a stunning boat you all have restored! Congratulations.
Been following this epic project since firs season. Seeing TH moving in the water, gives me bloody goosebumps!
Sounds like you can feel it through the screen also!
I LOVE Tally Ho and its crew! One of the most beautiful boats I have ever seen. And built especially well!!!!! Looking forward to future adventures! Keep up the killer work guys. May FAVORITE UA-cam channel!
loving these frequent videos thanks!
Love it Leo “so now we wait” English understatement! if you never make a mistake you are not pushing hard enough! A tad too much tech try swinging a piece of string with a tallow ended plumb bob. Kind regards Tim
It seemed so much bigger when you were working on it. Beautiful boat.
Best Contact
Yeah Rusty! Kind of like building a house. You walk the rooms on the ground and they seem tiny. Lay it out on the deck and they get a bit bigger. Put up the walls and they shrink again. That's where both design and construction experience come in, which keep you from freaking out at each stage. Also looks bigger below decks than above, I imagine. OK! Enough of this motor crap; let's hoist some sails!
Right? She looked huge up on the hard, and tiny now that she's wet. Reminded me right away of the old verse "“Oh God, thy sea is so great and my boat is so small.”
Boats are always bigger out of the water ,when you launch them they always seem to shrink a bit 😂😂😂believe me
@@simon-oy6umAnd they shrink again offshore in heavy seas.
she sure does seem comfortable in the water. just glides right along like shes happy to be there again.
I would have to agree with what seems the general sentiment about changing out the gear box. Think of it as a great chance to learn and show more about the mechanical aspect of the boat!
The video production work has gotten really sharpened up. What professional work!
He who puts it on the mud buys the port. As Paddy says two types of sailors… Lovely to see everyone smiling and enjoying Tally Ho as she was intended!
The big thing would be can you find a gearbox that fits easily (relative thing......). Changed mine and all I needed was to lower the engine on the mounts about 7mm and I fitted a new extended coupling. Would also want a commercially rated gearbox.. .. Great video and what a lovely boat she is.
This was a most interesting video! It's slightly alarming that such a small amount of either pitch in the prop or ratio in the gearbox can create such a drop in performance. However, like most things mechanical, it is not beyond the wit of man to correct it, as you stated Leo. The only other thought which occurs to me is that if the engine is allowed to rotate at the stated speed of 2800, will the generator and other systems be detrimentally affected? What about the various pumps and so on...will they run at that increased speed without burning out, melting the impellers, or running the bearings?
She looks beautiful under power, and creates remarkably little wash at both the bow and the transom.
You're absolutely right about ventilation. Added to all you said, there is also the air being used for combustion in the engine, which will also be noticeable when it is not there. An old engineer who worked for Mirrlees once said to me "a diesel requires just four things: lots of clean air and clean diesel, clean oil and a job to do" and I have always remembered this when doing work on diesels, even though this was over fifty years ago. I don't think things have changed much.
Bon Voyage...
Tally Ho sails beautifully! Congratulations and the video is great -as usual. You pamper us.
- If the gearbox does not affect the output of the electric drives/charger, go for it.
- It may have happened that you wanted to calibrate the ecosounder/depth gage. Otherwise, it is a fantastic coincidence you had 3 cameras on the exact spot: filming from the coast + George on the drone confirming he got it + camera on the boat + Nick in the bow (and one can see there is a mudbank from amidships....). Still that is the only way to really calibrate the depth gauge so well done ... and you add some drama and you avoid discussion on the comments of whether you did it on purpose or not.
"If you've never run aground......you ain't been nowhere!!!" DD
I have been motor boating for 45 years and never run aground so wtfu are you talking about.
@@BigWater59 Motor boats don't have 7 feet under the water line.....oh, and as the video said....LIAR!
🤣
Change the gearbox, optimise the system to original design spec. You and the team have produced a beautiful boat, looking foward to seeing her under sail.
For anyone looking for the historical videos of gearbox identification, here they are:

Hey, if you've ever moored a keeled boat at the Haven in Port townsend, you have been on that sandbar!
There's nothing like your first grounding, it keeps you humble.
Or at least, humiliated. In 50k NM I grounded twice, both time up rivers with shifting, unmarked sand bars.
Well done on replaying the run aground again. It's like you are putting old history into the new timbers.
Great Video! It is really splendid to see Tally Ho cutting the water. You mentioned that there was a miscommunication since you designed all the system for a 2.5:1 gearbox but the engine came with a 2:1 gearbox and you are considering both alternatives: changing gearbox or changing Propeller. I must assume then that changing the gearbox will have no impact in the electric motors' power/consumption and charging output?
PS: Nice story: I was sailing in a small sailing boat owned by the French navy with two French Naval officers in South England coast. I had the pleasure to see how we ran aground in River Dart, pretty close to the Britannia Royal Naval College in a low tide, and see how all the 3 roawing boats manned by british naval officer cadets passed beside the boat in their afternoon exercise. Being myself spaniard, every time I've seen my french friends in the last 20 years, I do not miss the opportunity to remind them that the french navy ran aground and 100 english "officers to be" that made a rowing parade to a heeling french navy sailboat.🤣
Changing the gearbox to the original specs may well increase the electrical output of the generators when they are being driven by the propellor (using excess sail power during favorable wind conditions).
Such great filmmaking to really draw out the suspense on the departure, knowing that we all know what's coming from the title/intro, then pretty quickly and matter-of-factly get to the point on the return when it actually happens XD
Commercial drone pilot here. Have you considered a launch cradle on a stick? Hand catching leaves your assistant's fingers vulnerable to prop stroke injuries.
I've seen other sailors attach a short stick to the bottom of the drone to make it easier and safer to catch.
The future looks bright indeed. Say, Leo, you might reconsider salt water flush for the heads. Seawater in the lines, and in the bowl, makes an awful stink as organisms grow. A fresh water flush system is usually easy to set up, and need only be used in harbor and locally. Not a matter of timely evacuation of the holding tank, it's the hoses and the bowl that go foul. On any offshore cruise salt water flush is fine, as waste goes overboard. The organism/stink factor also applies to seawater use in the galley, to save fresh. That pump will also stink if not flushed with fresh. Perhaps your system already takes all of this into account. Cheers and tally ho!
Leo has a Betamarine 85hp diesel. He needs to get the rpms up to 2700-2800 for max power/efficiency (rated at 85hp @ 3000 rpm). The prop-shaft and propeller are likely maxed out at 1000-1100 rpm since he commented they were near hull-speed. Sounds like a gearbox switch is indicated to get the diesel matched to the propeller better. The electric motors will also charge the batteries better in elec.-mode with a better gear-ratio.
Like I mentioned a while back also. Your slot flow cuts on the haul and rudder maybe not wide or tall enough. Basically causing vortices around the prop starving the propeller of flow water.
don't fret about it! I have personally unintentionally discovered about 90% of the sea floor around Florida in my ketch! I'm the local hydrographic surveyor's favorite sailor!
😱 My heart almost stopped as I read the title of this video (although I know that beautiful and sturdy built Tally Ho has a thick board as a sacrificial keel underneath the led keel. 2) To hear about the gear box problem made me kind of sad. I hope that everything will go well and that the correct gearbox will go onto Tally Ho's engine. 3) What Leo said at the end of the video is, amongst a lot of other things, what makes him so great and so successful: "That's not the end of the world. Just got to make the decision and get the work done!" So definitely no procrastination in sight on this channel! 😁 ;-)
As always: Thanks a lot for making teaching explaining recording editing uploading and sharing.
Best regards, luck and especially health to all involved people.
I grew up cruising in Maine with my parents on wooden boats. Sometimes watching these videos I see some detail that brings memories flooding back.
The propeller is already the correct propeller and was sized to work well to generate electricity under sail. As such the gearbox ought to be replaced.
I’m so enjoying every episode. And I can’t wait to see this boat under sail. It’s going to be exceptional.
Best on UA-cam. Thank you for letting us follow this amazing boat!
Have a great video
Hey Leo, First time long time..2017. Just had to say how beautiful Tally Ho is , her lines, water cascading off the bows waterline, etc.. Watching her go through the water on this episode was amazing. The feeling you must have at the tiller must be overwhelming thinking back to that dollar. I built my first too and remember that pride. Well done, perhaps we will pass each other at sea some day.
Watched every video from the beginning as they have been posted. Only commented a few times but liked almost all of them (I forget occasionally). The current issue is a no brainer. The entire design and build has been superb from the beginning so there is no reason to change now. If the mistake on the gearbox was in the order then you must suffer the cost and replace it with the designed one. If the order was correct and the supplier got it wrong then they should replace it at zero cost. Either way the solution lies with the gearbox as originally designed. To change the prop would be deserting the original design in 2 ways, gearbox and prop which is not acceptable. Good luck Leo, I'm sure you will make the right decision. !👌👍👍
Aye aye!
bloody well proper, time to walk the plank laddy my boy who ever grabbed 2:1 inventory and the installer not cross checking gearing ratio needing to be 2:1.5

Stick with your original design-plan for the correct gearbox ratio mate. IM-biased-HO, it's unlikely Leo's 'ordering mistake' because everything about this project has been such smooth sailing; well almost. Anyway I say, "Leo olde boy, go with your original best intention." P.S. Crew & boat together have awakened & uplifted many souls to the timeless great craft of wooden boat building. Thank you & congratulations Leo, crew & extended family. Cheers from Sydney, AU.🤠
I remember helping a friend change the pitch of a Max Prop underwater. It took four tries, but we eventually got it! The boat is looking great!
im amazed how beutifull the boat is, good job lads u made real mark
Tally Ho motors so beautifully along her lines. Great job on the docking Leo. Thanks for sharing another well done video.
Carry on
cheers. Bravo Zulu 🎉
Btw Tally Ho is stunning from the drone shots. Gorgeous
Amateur engineer here: change the gearbox to the original spec. A smaller prop would likely be less efficient for low speed propulsion. Also, the original (larger) prop will do better than a smaller one when using it to drive the generators via boat motion. I love the idea of using the "excess" power available from the sails in favorable winds. Once hull speed has been reached, you want to be able to harvest as much electrical energy as possible-the original prop should be better for that.
“Trust but Verify” is the phrase that comes to mind in this situation that you found yourself in. No matter the choice you make the results will be top quality! Like everything that you and your team do!
Change the gearbox. It will enable better throttle control
Does the electric motor go through the same gearbox? I'd want to test the electric system as well before making a decision.
@@ColinWatters Surely it does. There is only one trans.
@@ColinWatters looked to me to be on the output shaft side of the gearbox and separately controlled, which would mean that the electric drive and sprockets are matched to the current prop.
Glad to see no harm, no foul. Plus, you've knocked the new off her hull so full speed and following sea ahead.
If you had told me that running aground was part of sea trials the same way you had me convinced about the front door I would have believed it.
God, that front door gag had so many of us palpitating unnecessarily. Great fun in hindsight, but way stressful at the time, lol.
Front door felt weird but I trusted Leo. The ultimate betrayal.
When it comes to changing the prop or the gear box, you would have to consider the electric drive and also what is best for charging the battery's under sail. You would want to make the change that will complement these extra systems.
Hi Leo, shit happens...
I whould suggest you to change the gearbox for 2,5:1. As far as I know, always slower running props are desired because of more efficiency. So it should be short term and long term cheaper.
I hope any professionals can confirm that.
Regards!
I agree. Is not the manufacturer responsible for this “mistake.”
As I understand it for a for displacement hull a relatively large diameter propeller turning slowly is more efficient than a small one turning fast so yes its better go for the lower ratio gearbox . (might not apply to a planing hull )
@@henrymorgan3982 "Communication error" sounds an awful lot like someone requested the wrong box. These things happen on big projects, just gotta grit your teeth and rectify them.
@@henrymorgan3982 The manufacturer has probably taken responsibility for the miscommunication, or at least offered to swap the gearbox for a reduced fee, hence Leo saying that it's cheaper to replace the gearbox, but it takes more work. It's not exactly the manufacturer's fault that the gearbox ratio was spotted at the time it was in the water, that could have been spotted much easier (but it's also understandable that nobody checked this particular aspect).
@@isfiyiywafibc6qaiiiiiiiiii570a large bronze feathering prop is an expensive bit of kit, there's not much economy of scale in that sort of thing, while all sorts of machines use a gearbox, without looking it up I could well believe it is simply cheaper to buy a new gearbox than a new prop.
I agree you did the right thing getting the boat in the water. Project management techniques will tell you exactly the same thing, try and move forward to see if any of these sorts of issues are highlighted. Keep up your positive attitude, love it.
That title caused my heart to drop I love this boat so much it is painful to think of some of the work being undone and delaying the voyage.
Yes I was imagining all that beautiful paintwork being scraped off.
You never worked on a boat before.
It's ok if she runs aground, because of how she's built. Not much damage can happen. It's when you're stuck and the water goes down that things get risky. Also, she has a long time before she's out of sea trials. No voyage any time soon.
Just think of it as Tally Ho remembering that time back in the 50s when a grounding ripped her whole side open. She knows that boats always run aground, and she wanted to get it over with easy, so that the coral reef doesn't happen again. Boats might be inanimate objects, but they still have feelings. I believe that anyway. I've had too many motorcycles, planes, and boats with personalities to think otherwise.
I see some true joy on the crews faces - even when challenges arose. Wishing you all the best and looking forward to watching you work on other projects while the gear box and propeller issue gets sorted. Really looking forward to the capstan install!!
Been here since the beginning. Hoisting a cold draft for Tally Ho, Capt Leo, & crew. This channel is why I smile. Jolly good on ya!
These videos are just edited so well. Can't wait to see Tally Ho under sail.
I know there’s still a lot of work going on, but it is so nice to see y’all enjoying such a beautiful boat. Cheers!
I did this off the coast of Kodiak once. Middle of the night we rested on the rocks for a few hours. We also turned off all the lights and hid through the night and floated away as the tide (25 foot tides in Kodiak) lifted us off and let us return to port. Not embarrassing to tell the story but so glad the coast guard didn't see us.
Avoid doing that in Hawaii. They'll drain your whole family's bank account and sink your boat.
Been stuck Admiralty Inlet and Apple Tree Cove. Great video.. was painful watching the hole get cut into the deck..
Don't forget to review the motor/alternator side of your drive system when deciding whether to switch out the gearbox or the propeller. It's likely the unit shipped with that gearbox because it is matched to the motor/alternator side of the system.
Good point!
The gearbox doesn't matter to accessories that drive off the crankshaft, like Tally Ho's. Driving stuff off of the gearbox, like PTO shafts driving hydraulic pumps and such, then the gear ratios would matter a lot. You can check that out on the Fabrats video building a wrecker. They drove the hydraulic winches off of the transfer case's low range gears and they could pull a house... but only at about one foot per hour! 🙂
Go back and watch the second half of episode 115 where they uncrate the engine. Leo pulls the cover on the hybrid drive system and talks about it. It looks a lot like the timing belt on a DOHC V6. The PRM hydraulic gearbox that gets bolted to the diesel output can be supplied with different gear ratios. But that gear ratio combined with the tooth ratio of the drive belt pulley ratio will have to align with the speed range of the twin 10kW motors. So I think that he is stuck with the gearbox ratio that was supplied and will have to match the propeller to the hybrid motor and not the other way around. But for sure it will be fun to see how they resolve it.
I am so happy to see this boat on cruise again. Great work u guys did here, by far the prettiest boat i have Seen.
Big respect & thank u for Sharing ❤
I would opt for changing the gearbox rather than replacing the prop. That way you don't have to haul the boat out of the water, which is also an added cost. Tally Ho Leo & Crew! 👍👍
Really sorry to hear about the wrong gearbox being installed.
Tally Ho just wants to live life to the fullest right out the gate! Can’t wait to see her sail!
That boat looks so good underway!!
I'll bet the gearbox is designed to have many "common parts" both externally and internally, It might be possible to swap the two gears that currently provide the incorrect ratio with two other gear wheels that mesh together perfectly using all the stub axles and bearings etc internally, to produce the required ratio.
It's just a few teeth less on the little driving cog and a few more teeth on the transmitting cog after all,. Externally, the casing and all other parts are quite likely to be identical. A few hours swapping the gears and you're good to go 😁
I was wondering about the same.
might be even less of a hasle if the gearbox is just one single unit they can replace, then it would only be a problem of dicoupling and hauling out the old one and reinstalling the new one, but if the space around it wont tollerate that it might indeed be posible to swap gears, if the gearbox has enough internal room to allow for a bigger gear
You could even swap the gearwheels without taking the cockpit out. I'm sure Patty is our volunteer for this😂
@@jerryf609 Looking at the innards. not a simple swap. this unit has a clutch pack on the input shaft, its not clear if the shaft is splined or pined.
First of all - a beautiful boat! Great job Leo and the whole team! Regarding the problem of gear ratio mismatch, it seems to me that it is worth changing the gearbox and saving the calculated data. An enlarged propeller is violence against the system. And, when sailing, it will give more resistance. It's up to you to decide. Good luck and thanks!
I think he's going to change the gear box. Let's see if I'm wrong.😁
Shirley he only needs to change one gear in the gearbox?
And stop calling me Shirley!😂
@@markrainford1219have you ever seen a grown man naked?
I hope he does make that choice, but you may have noticed, he gave a heart-like to one commenter who made the case for a prop change. That troubled me a bit.
@@llagas6307 I think that he was just be gracious. The "gearbox" vote is overwhelming!
Well, for her first grounding, at least it was in soft mud! Seems like you need a nav screen in the cockpit to be able to monitor her depth....

I've heard it said,
There are two types of sailors: those who have run aground, and those who are lying about it
Well that's me covered then because I ran aground last night. Went to drop the hook and it would not run out. Then I remembered I had just had some work done on the rode and I guess the guy that did it didn't stow the chain neatly enough and it got lodge inside the hawser. So had to put her on the beach in a flat calm falling tide for the night. Consequently, I couldn't set the anchor properly and when the tide rose at 2.00 this morning we went off on a little wander amongst the other boats. Managed to re-set the hook but then found that when the tide returned mid morning, I couldn't get of the sand and while it had been like a mill pond last night, not so this morning with a stiff onshore breeze and a considerable chop driving us father into the shore as the water rose.. Eventually managed to physically heave in enough chain to enable me to get into deep enough water where I could use the engine to rip it out of the sand and motor out into deeper water where I was able to eventually get the anchor onto the deck. Sailing single handed has it disadvantages as well as its benefits lol.
