We need to get Brupeg up to top speed and hold her there so that we can calibrate and test some of the onboard systems. Duncan was onboard for the week and managed to sort out the wiring chaos under the dash and tidy up some last minute BruNet projects so we have a full suite of digital gauges working up in the bridge and reading accurately. While Duncan was busy in the wheelhouse, Birk was in the engine room finishing the small genset exhaust.
It was a good test, we found some issues on the boat which we will need to address in the coming weeks, and we now know Brupeg's top speed!

Thanks for watching and for your support!
"Boost the boost and save the juice, and you will get home to roost" - RAF motto for pilots in WW2. When I ran roadtrains in the 1990's with a 350 Cummins, we flogged them 100% load factor all day. Usually got 1 million kms before the main bearings would wear out. Now there is really good synthetic oil........its hard to know how much further they would go.
It’s difficult to convey in a UA-cam comment how much I appreciate seeing your videos.
Thick or thin, you carry on.
Tickety-boo!
Thanks so much
same
Thanks to ❤
Brupeg looked awesome underway❤
She cuts through the water beautifully, sounds great also!
Brupeg looked amazing. Can't wait to see her wings lowered into the water.
A true mate, and amazing crew
Have a great video ❤ Good work for you 🎉🎉
The violin and magazine antics are hilarious!
Very very nice ❤ Best contact 🌹
You should get an RJ45 crimper so you can make your own Ethernet cables that are the exact length that you need.
We have them, we just don’t have the time to do that level of tidy up
@@ProjectBrupeg We have done a few that way.
Full steam ahead. 🚤👍
'Steam' thought they had a deep fat frier down the back lol
TOP SPEED?
10.2. This test. Should see a touch more with some fixes to the throttle cable
Your next project is to refit Britain's Nuclear Submarines
"watch your balls". Listening to Jess laughing hysterically in the background had me laughing as well. As for your radar, you may want to change out that mounting plate. It is way to thin for the places you will be going. (along with the legs) Great work Duncan. The boat is looking fantastic.
Listen love what you have done with her i live in rhoad Island but have worked on boats for over 25 years so if you need help with anything let me know brother
LMAO. Taking a leaf out of the Casey LaDelle book of trolling (re the parking...)
My old man started watching your channel about 5 years ago, he loved seeing your progress and it helped keep him entertained during the covid lockdowns in Melbourne. He normally used my UA-cam login so even though he died last year I still see your updates pop up.
Dad never got to see Brupeg up and running but I’m sure he would’ve been thrilled for you both. Never thought I’d be crying over a boat but here we are lol.
Thanks for sharing your journey, congrats and safe travels!
Thanks Sophie for letting me know us know what it meant to you and your dad. We are sad to hear of your loss. When we are underway for the first big trip, we will be raising a glass to those that can’t be with us.
We’re thinking of you,
Jess and Dame
Hell yeh big respect to Duncan! And loved your violin parking 👍
lol maybe some folk should use this method when driving there car 😂😂
@@kiwicol7383 Driving "where" car? *There* is a directional adverb. *They're* is contraction of _they_ and _are_ *Their* is a possessive adjective, and is the correct word to use here. You're welcome.
Good work ❣️
Wheelhouse electronics are best cooled with fan exits on top, pulling cold air from below. This takes advantage of natural heated-air buoyancy, & easier on fan(s) especially if they are controlled by thermostat. Radar & sounder boxes might have cooling fins --- if so they should be oriented with fins aligned in the vertical direction for easier cooling.
You can see Duncan is an experienced technician. Nice instrumentation set up.
I would of gone to a MPU out of the flywheel housing for RPM rather than the alternator for a more accurate reading through the rpm.
Cummins PT fuel systems primary source of power validation is fuel pressure with boost being secondary, however still important and still an indicator.
You are correct with the engine not reaching rated speed. Very important to get this right.
I am not sure whether you have a bitza engine or not.
Do you know your Fuel pump code and CPL.
This should be on your fuel pump tag. First 4 numbers reflects the CPL and the second 4 numbers reflects the pump code.
A common NTA855-M CPL is 0700 and Code 9619
Specifications are
Fuel pressure - 154 - 170psi
Intake Manifold Pressure - 33”hg - 43”hg
Max Exhaust Back Pressure: 40”H20
Max Fuel Restriction: -4”hg
Max Fuel Return restriction: 4”hg
The correct way to get the best data to make a call on your prop is accuratley measuring fuel and Intake manifold pressure with a calibrated gauge.
confirm you are getting full throttle
Use a hand held tacho on the crankshaft damper and do a full throttle run into the tide or wind and collect the pressures and the rpm
The data has to be accurate.
Unsure if you have validated your fuel and exhaust restrictions.
You want to get your glycol to 50%. Best protection for your liners
Great to see Brupeg underway with her sea trials...very handsome she is, great helming Dame ;) ...Thank you.
Hello farind 🌹 Good Life 😊
Hope you can sort out Linux problem with OpenCPN. Windows is very heavy on background data over expensive data links. There are options for limiting this but they are only partial.
LOL Love the docking. : )
It was all real time too…
Amazing very nice ❤
Amazing progress! About those exhaust drain valves - are those ordinary plumbing ball valves? If yes, then they have plastic, like PTFE around a ball, which starts to decompose at around 250-300 degrees C. It also starts to release toxic gas at around 250C. Just FYI. Cheers!
Dame, you may want to consider a bridge/engine room intercom.
Buddy, that steering wheel is embarrassing, someone please donate a proper spindle wheel.
I noticed that when you were running, the crane controller on the bow was bouncing around. You might need a cradle to locate it.
If the trolley is in the water, you could try magnet fishing ;)
Pick up the fenders please when you are running.
Suggestion: When you have all engine parameters sorted, you might consider a full power workup. Any temps not on the bridge panel place thermometers tape them down at these points. This trial should take 3 hours. Take readings every 10 mins. While you increase speed slowly to full power. Over an hour. at fullpower still taking readings every 10 mins for an hour. Reduce your power down to idle slowly for an hour let the engine cool down. Compile all this info including air temp date, sea state, tide outside air temp, time of year/day and fuel consumption. You have performance data for Brupeg as new.If you lift out say every 3 years complete another power trial before lift out you can see either high or low temps that will give you a bench mark to work from. Love the channel.
Very interesting info.... Seems that the same might be good for a gasoline powered engine, correct?
Nice strategy, thanks. There are certainly some longer and structured runs planned for more comprehensive testing and data collection. The main objective of this short test was to calibrate the numbers of the Brunet sensors/systems against reality and redarc, mostly the EGT, MAP and gearbox oil pressure since they are the new kids on the block. All of these are active sensors, so they turned out just fine as they had been set up against their datasheets. We had planned to do up a table of measurements for both the engine rooms instruments and the wheelhouse measurements, however the exhaust leak made the engine room a hostile environment, so with great care, we made a couple of measurements and I got out. Thats why there wasn't much video around the actual testing/measuring. We also do have data logging for all measured parameters, but really haven't used that in anger yet, but will do so soon.
Good work ❣️
@@duncancampbell62 So, part of the upgrade to Brupeg should be the fit of breathing masks fitted in the engine room and a remote air supply (maybe, also a camera in the engine room aimed at the gauges and surrounds monitored at the bridge)?
Yes indeed. Plus a CO2 purging system and interlocks to prevent anyone getting caught in the engine room.
that was so cool, I had to laugh at your pioloting skills, excellant lol.
EGT probes belong in the exhaust manifold at the turbo inlet. The important temperature to know is what’s coming directly out of the exhaust ports and into the turbine. The turbo soaks up so much heat energy that the post-turbo temperature is low, delayed and essentially meaningless.
Love the project! Great to see her run up to top speed.
With the Cummins water called manifold it’s not possible to put EGT probes into that side of a turbo. We have run the engine on the dyno with the probe on the exit so we know the temp range we need to work within
Is there a diagram for Brunet? Interested in how signals go from sensor to screen. Something like Sensor>signal conditioning>A/D conversion>NMEA 2000/other multiplexing/RS232 conversion?>Pi>gauge software. Or something like that. Maybe I missed an earlier video?
We’ve not put that level of detail out on an episode. It’s possible we will do a spin off tech episode on BruNet once it’s more complete. We are about to swap out the current piece meal circuit boards for a custom printed version so likely will wait to show the tech when that’s onboard and running
Have you given any thought to making your little bow mounted crane stowable ie.(below deck) I think corrosion won’t be its friend. 😮
So our thoughts around the bow crane is this, its not quite long enough so we need to extend it. That all said we have never needed to move the top arm in and out to adjust the lifting capacity (its always fully extended). and its made from mild steel and painted poorly so wont last and is showing rust in most areas. We have never thought about stowing is below decks as its quite heavy and we do what we can to limit lifting heavy stuff where possible. What we have thought about is building a copy in stainless and making it slightly longer and giving it a bit more bracing to allow for the extra length. As for the winch motor, thats always the weakest point from a corrosion point of view so we have thought about making that live below the deck level inside the anchor room. with the cable going up the inside of the crane box section and exiting out the end of the crane jib. its not a perfect solution but we think it will greatly increase the winch life and also means we wont need to try and protect the crane from corrosion or knocks and dings in the paint in the future.
Duncan is a treasure!!!!😊
Good work ❣️⛵
15:51 Exhaust U bolt clamp is loose when engine is started.
Bloody good attention to detail. Thats actually a clamp that I (Damien) loosely put on there to remind me that i need to build a mount to support the exhaust up there. Its hand tight, but clearly thats not tight enough!
Duncan would make a good politician , after he finished speaking i have no bloody clue as to what he has said😂 his iq issuper hi,cheers.
Damien playing the fiddle whilst bringing Brupeg alongside was the funniest thing I’ve ever seen ….. and I’ve been a charter skipper on Sydney harbour for years ! 😀
The big advantage of complex expensive digital controls versus old fashioned analog dashboard instruments is that when the digital dashboards go, everything goes dark and it's too complicated to figure out. Whereas analog dash instruments last generations and are rugged, cheap, and simple.
Good thing we have both and redundancy on all systems.
@@ProjectBrupeg Good.
😊😊😊
Are you going to get rid of that wheel and put a toggle on. So much easier to steer
Actually changing it to a stainless destroyer type wheel but the taper on the wheel is wrong so we are machining a new hub to suit
Seemed to be very well behaved even against a little bit of chop. Nice!
That dry exhaust sounds so sweet, around the 18' mark. Well done. Looking forward to seeing a real test of the batwing stabilisers; we're living on a cat presently, but most likely will go back to a monohull and we'll need these too.
Just a quick reminder that cats love the taste of engine coolant! Once ingested, antifreeze can be absorbed within about 40 to 60 minutes. Antifreeze and cats are a very toxic combination - even a very small ingestion can result in severe signs of antifreeze poisoning and potentially death. Only a teaspoon or two will poison a cat, while three tablespoons will poison a 15-pound dog. A dog only needs to ingest 2 to 3 milliliters of ethylene glycol per pound of body weight to get a lethal dose of the toxin; cats only need to ingest 0.64 milliliters for the same effect.
Ok so if we find her licking the coolant tank we know it’s going to be a rough night. Luckily she has zero desire to go onto the lower level on the boat (never even been down once) let alone head into the engine room.
She looks so poised steaming through those swells. You can tell she really wants to get out there and play in the big seas.
Yeah won’t be long now. Genset here maybe tomorrow or Wednesday. Lifted onboard as soon as humanly possible after that. Maybe two weeks of work in that job then onto the energy system install. With that done (hopefully 4-5weeks tops) we will be set to leave
The Ship is looking good. Almost finished. Time for a 5 day run on the ocean to check everything out. Possible 7 days shake down with everyone abord and yes that Fresh morning Coffee on the Bridge. Get Kitty a Life Jacket and Homing Device with a Flashing light. I had one for my Kitty.
Cat life jackets start from around US$20. Seems like a no-brainer to you and me, but would the cat bother or even remember to wear it?
@@ObviousSchism Depends on the Cat Scan Results.
I would like to hear the sound of your violin playing... or maybe not. :)
When are you going to test the stabilisers? I don’t quite see how they will actually help stabilise the boat. Large cruise ships and the QM2 have stabilisers, but the stabilisers, when deployed, will rotate along their length like the ailerons of an aircraft. Thus if the ship rolls to the left, the lefthand stabs will rotate leading edge up, the right hand stabs will be leading edge down and will pull the ship toward upright. I may be wrong but yours appear to be fixed and will roll with the hull. But you’ve all done an amazing job with this entire endeavour.
Hi Geoff, the wings will be one of the first things we test once the electrical upgrade is finished. They are passive stabilisers. They work in the same way as wings on a plane. they won’t counteract roll like active stabilisers but they are not designed to do that, there designed to dramatically slow the roll down. It’s very hard for the hull to lurch left and right when you have 6sq meters of surface area and water weight to lift compress each time it wants to roll.
@@ProjectBrupeg thank you for the explanation. That certainly makes sense to me now! I’m an aircraft engineer and looked at it from an aeronautical point of view. Love your work and can’t wait to see more videos. Thanks again.
Well done, she looks great under power.
Good work on crowd funding, I'm impressed that BruNet has Only Fans!
Do you have or plan to have an auto pilot for the boat? I imagine with the long trips you guys will be doing that would make life much better on the bridge and also improve fuel economy since you will always be gong in the straightest path possible.
Yes we do have one but it’s yet to be installed. It won’t be long now and we will be hanging out for it!
Talking about corrosion, I gave you a box of "Cortec Pads". I used them with great success in the Electrical industry, protecting small signal wiring etc. But knowing you, you have probably put them in a safe place eh. LOL.
Actually I did put them in a safe place and blimmin forgot all about them but they are absolutely spot on for this. Thank you again, I’ll grab them out and fit them today. Cheers Dame
Looking good, couldn’t help noticing the wake around the sides where the side stabilisers are mounted? Would deflectors help reduce that wake & drag? Just a thought…
The new docking procedure had me totally busting a gut!
At speed she looks like a coast guard cutter 🤗
Nice footwork at the helm, whilst reading a magazine and playing the violin, Damian!!
They're just a few of the outstanding skills you won't see anywhere else on UA-cam🤣👍
Couldn't agree more!
Hope you add a muffler
We have one on the to do list
Which of course you did do. My bad.
When the apocalypse comes how will you escape the zombies when there is no supply of diesel?
Yes, these are the issues that keep us up over thinking things at night.
@@ProjectBrupeg You know how they pitched the movie Alien as "Jaws in Space", well I think there is an ozzy movie in "Mad Max with Trawlers". Starring the Bigger Boat.
"Clear prop" 😂
Love seeing her under way, great work, you should be proud (I'm sure you are)
It worked, nobody has been injured by the propeller on any start up we have been in charge of. Statistically speaking, its a perfect solution
Another great video. Thank you. All my best to the Crew. I hope the Admiral keeps getting better. Hotglue Tip: Hotglue will release with denatured alcohol.
The sound of the Cummins is the best part!
startup in the engine room was music
Not only does Brupeg look good, she sounds good too. The engine purrs like a kitten.
Whats with all the untrimmed cable ties everywhere?
Anything in progress wont have them trimmed, anything finished does, thats how we know something requires more work.
I think this has made me realize I might be OCD lol
It was great to see Brupeg cutting through the swells at 10kts!!
I see Duncan is using Certified & Goverment Approved ESD Safe Cardboard xD
Just curious - after all the effort you put into the engine alignment are you happy with the outcome?
Yes. Very. The mark of getting it right and being so anal about the alignment, is we forget about it now because there is zero vibration or noise from the shaft.
@@ProjectBrupeg Wonderful - she looked so fine out in the channel. You must be proud.
Are those flopper stoppers on the side of the boat? They seem to be making a bit of drag. Have you thought of giving them a sharper leading edge?
Check out this video as it will make more sense when you see the whole wing
Brupeg gets her wings back - Ep.309
ua-cam.com/video/Y3ZD7SgNFJg/v-deo.html
@@ProjectBrupeg An interesting design. I hope they work well for you.
Thanks, they are quite common in this part of the world on trawlers around our size.
If you have starilink you could ask if Duncan can do diagnostics remotely for minor systems bugs? It is an integrated system and Victron is well known for it?
Yes we currently do that via our Starlink connection
@@ProjectBrupeg Yeah, I do quite a bit of work remotely via vpn. It amuses the crew as when I make sw changes and restart Brunet, the startup Butcher Bird call sounds. I can continue to do instrumentation tune ups and calibrations remotely as more tests are done and more is learnt about the performance of Brupeg.
IT guy here: if you're using off the shelf networking in an ocean environment, especially with CAT5/6/etc, those tiny pins can corrode. Not sure if available in Oz area, but get some CorrosionX Aviation ($30 in USA). Spray/pour into a small cup and use a brush to coat the connectors, then plug in. Also make sure your networking equip is properly grounded. Make sure long runs are tied off - thin copper will work harden, so avoid any stretch that can oscillate.
Very relaxed damein at the wheel. Let's hope final installs go well.
Smorgasbord lunches while at sea would be a treat. Crane at front needs a cover. Well done amazed at what you have achieved so far.
Steering seems quite stiff, a touch of power steering would make the turning maneuvers a little easier… that or mounting an outboard on a shaft from the bow.. kinda like the electric ones used by ppl on their little runabouts. ( yeah, I’m joking ) - Awesome project to follow, well done. 👍
Your wings must add some drag ....
She rides pretty well for a fishing boat. The engine sounds nice too.
Good tip for landing the drone espesially if space Is limited or the grounds moving,
Hover the drone at chest height, grab it from underneath and quickly flip it upside down, it thinks its crashed and shuts down, doesn't hurt it or hurt you (if you do it right ha)
Loved the "CLEAR PROP" prior to start!
Yeah, a habit both Dame and I picked up from my pilot training. Although partly tongue in cheek, it does serve as part of our start up procedure for safety reasons
The full-power instrument calibration test sounded really interesting, a little exciting even, with the prospect of finding out Brupeg's top speed, economy cruise and fast cruise speeds, and how the engine room instrument readings compared to those in the wheel-house.
I was a little disappointed that you didn't share any of the calibration procedure with us. Beyond a wide angle wheelhouse view of Damien operating the throttle, the instrument display wasn't legible, so we had little idea what was happening. At 29:06 Jess commented that Brupeg was doing 10.2 knots, but without telling us what the throttle setting was or what the revs were.
It was interesting to learn, at least, that the max revs achieved were a little low, likely due to prop mismatch or a throttle cable issue.
There was probably too much happening for you to keep us in the loop as much as I'd hoped, and I'm sure we'll learn more details in future episodes. Everything is looking really good so far, and the next sea trials will be epic.
Nice work on your more relaxed docking procedure!
Spot on with too much going on. For this test it was Duncan and Dame only on the bottom so few hands to do a lot of data collection.
Much better parking Brupeg this time. Just a little more practice on the violen as you slip the stern close to the doc and you may get 5 of 5 stars on parking! 🎉🎉😂
It would appear that one of the jobs is to clean and put away things maybe paint the floor and bulk head outside ? Whats the top speed on her ? my guess is 15 knots .
Good to see you two so happy as Brupeg finally get's ready to hit the open sea. Congratulations on such a hard slog for you both. It has been great following you two along over the last few years. All the best out there.
For diesel engine exhaust leaks look for soot on the pipe that is where you'll find the leak.
Yes. So far we haven’t found much at all. We are fairly sure it’s the slip joint which is an easy fix
@@ProjectBrupeg good luck on getting out to sea
Dame, a suggestion if I may for Bru-net. I know you have an RPM readout there on the bridge, but what may help future diagnosis, and fouling or engine performance monitoring would be a throttle position feedback sensor. That will enable you to build a chart showing normal rpm and speed for a set % throttle, will give you an easy way to check if the throttle cable has broken (move throttle lever, no engine response, if position sensor indicating no change...) decreased rpm's in flat water for throttle position will also indicate lowered performance or wear within components etc.
Will go much faster when the engine cooling pipes along the bottom of the under hull are removed.
It’s crazy isn’t it?!?! Normal I guess for a fishing boat that spends a lot of time with the engine working hard dragging nets through the water.
Hey was the tide going in out guys?
Was pretty much slack low tide. About 40mins from the change so very little water either way
@@ProjectBrupeg You guys do excellent at answering all the questions. Thank you. 👌
WATCH YOUR BALLS!
Indeed
Bloody beautiful work gang you guys earned this beautiful vessel, fair winds and following seas
No carbon monoxide alarms or sensors in the boat? Especially in engine room?
24:16 dunno man... you just don't have enough flair with a shoe on. Have you tried it like the MCM boys did, barefoot? You have to be able to grasp that wheel. Let them fingies fly free!
If she doesn't plane, it's a waste of fuel to plow through the water at 14 knots. 8 to 10 knots is all you need.
A proper little ship you've got there! It looks great underway at speed.
Formal attire...I love yo both so much
I can’t wait to see the first shots from the wing mounted underwater cameras!
Great episode. Loved the drone footage.!!!!
Burpeg looks great underway!
More sea trials and new to do lists. Tidying up. 3 weeks before Duncan returns.
Fantastic episode as usual, love that you are offering Patreon for free, hope that is not costing you at all.
Great to see you at full power
I would like to see the boat at sea in some rough stuff be a good test for it.
World cruiser you build there ! Engine strong and gear also capable of the strain …..Good luck to the first quest !
Damian,you big docking show-off😂😂😂😂😂 love your channel!!!!
I appreciate that
Why EGT after the turbo? Easier to weld a bung I know, but will be a false (lower) reading than actual. Not a problem if you have a good idea of temp drop across the turbo.
We have a water cooled manifold so no possible place to fit a pre turbo probe. We know what temps we should be seeing from when we did the dyno run and they match to what we were seeing
Bueatifully said about Duncan. However both of you have achieved so much and created this project from the bottom of the waters!! Amazing project.
Wow, thank you!
After all these years how good is it to see Brupeg out on the water cruisin and lookin so so fine! Good jo team
Duncan MVP for sure. Also Berk
With the exhaust leak, did you remember to close the drain ball valve?
I think the engine room would have been too smoky to see anything if they had been left open.
