This is one of the best boat rev iews I've seen. i must admit that after watching this video I have no questions as they'Ve all been answered in the 27 minutes. Great job!
Hi , Dan , writing my comment about your excellent presentation , one evening anchored in an Adriatic cove , after few drinks , it was easy to make mistake . Your kind answer proves that you understood what I wanted to say. Best regards.
Without doubt the most informative and engaging review I have ever watched. Thanks so much for the wonderful clarification on a few points about the hybrid system that I always wanted. Subscribed and looking forward to more reviews although I think this is the boat.
Beautiful vessel, very good review and cruise! Music could be better but it is about the ship not the music. Wish I was there with him taking in the ride. Once again very well done ( the review and the boat). Thank you.
Nice family boat. No stereo system, although wouldn't be hard to install one. Grandma hates it when she can't get back into the boat and we have to leave her floating in the bay.
hey Dan - best YT yacht reveiw I have watched - so refreshing to have the controls fully explained - would have liked to see the anchor working and mooring leave / exit thanks again I have subscribed for more !
Living in Croatia, on beautiful Adriatic coast (Dubrovnik) and hoping that we can diminish the CO2 impact , I can not imagine better boating then with hybrid boats ( before we turn to full electric) . Excellent job in presenting the Greenline 40 !
Wir erinnern uns noch an die ersten Greenline, die wir auch probegefahren sind uns dann dagegen entschieden haben. Faszinierend zu sehen, was für interessante Yachten inzwischen daraus geworden sind! Zudem: Kompliment für die perfekte Vorführung.
My German is very bad but i think you're saying that the presenter great, actually the greatest presenter on UA-cam and that he should do more videos like this for the great people of Germany. :)
Great walkthrough video. Just one suggestion: add a link to your website in the description and maybe a link directly to the boat details (specs, price, etc), for the boat you are featuring. Thanks.
Crikey! Thank's Ken, i'm l'm just learning by doing when it comes to UA-cam so really appreciate the feedback. Trying to make each video a little bit better and your comments really help. Cheers
No worries. That Greenline 40 and its bigger sisters are beautiful boats! I live in western Japan and the 40 or 45 would be perfect for cruising the Seto Inland Sea, also longer stretches to Okinawa and the Ryukyu Island chain down south. Keep up the good work! Looking forward to more of your videos.
@@AlfDog1955 Hi Ken, i don't know much about cruising in Japan but it looks amazing on Google Maps. I have been aboard a couple of 45 Greenline's and they are next level in terms of space and facilities (also price lol). We will list more Greenline's on here in future but i have started another channel ua-cam.com/users/BoatLife_DansBoatLife where i am just reviewing and testing boats so feel free to keep an eye on that too.
Quite honestly, I expected better from a hybrid craft. It's very simple to fesign and install a very powerful drive system fed from a generator which, in turn, can be fed by a small, efficient petrol or petrol/lpg engine. About 1 litre capacity which charges the batteries simultaneously. Using IPS drives this can be a fast, efficient and silent power-plant which takes up very little physical space, (about the same as a pair of diesels + 10%). The boat itself appears to be very well designed, making excellent use of available space...and the presentation was extremely good and one of the most informative I've seen. Thank you very much.
Yes i think that could be the future of electric boating. Hydrogen cells and electric motors for example. Will be exciting to see what happens in the future
@@theboatbrokerage : thank you for your reply. Hydrogen at sea? Probably not a good idea; even in tanks, hydrogen doesn't like to be shaken about too much, and it has to be kept at a very low temperature to be cost-effective. I am currently working on a solution which is capable of running pure electric for long enough to take a 50 foot boat across the Atlantic at an average speed of about 25knots, without using petrol/diesel for more than 10% of the journey. I was very pleasantly surprised to discover that such a feat is not only feasible and cost viable, but the technology already exists. It's just a matter of using it efficiently and thinking "outside the box" to put the whole thing together, up and running.
Dan , just one small observation : showing how simple is to open the stern fence inverting it to simple access to shore. Small thing , which could have a big marketing impact.... Otherwise THUMP UP for your presentation !
How many more years will it take before most shipyards develop an all electric model yacht? Noise and diesel fuel reduction seems like next level goals, customers can appreciate.
In your case moving at 5knots hybrid is diff prop need than traveling at 15knots diesel prop. So ideally the hybrid mode would hve similar 10 knots speed or hve diff shaft & prop or adjustable prop pitch still needed like gas & hybrid. Or U need a studded inline prop rather than a hole inline prop design. Meaning u r hving 3 & 3 blades inline but stud blades mean more setup for lower speed less loss efficiency in hybrid mode than diesel dialed in. U want max low speed bite & push no reving /turning speed(under 10knots setup).
I don't like standard nose down blocking flaps but they clearly save fuel, but being able to shift water load forward or getting ship weight bal better hull size & tank placement in boat esp small to med size beats blocking flaps unless at sped.
Would the power and efficiency be different if the shaft propeller was driven by a an electric motor powered by diesel generator or the shaft propeller powered by a straight diesel engine?
excellent review, thoroughly enjoyed it. trying to decide between this boat vs the 39... i guess single diesel vs twin diesel is main difference. little more beam on the 40, and those stabilizer fins i’d probably break off on the ocean bottom in the first week, haha
39 is a faster hull design - think more Down East style. The 40 has more redundancy with the twins. Stabilizer fins have been fine on the many ocean triips i've done and help the boat track nicely in a following sea.
So in the middle special end of the scale a good prop best metal working sea & best pitch sized diameter for load either holed or studded fine tuned 85% efficient if working not racing motor can hve
If over 80 knots power racing the shaft is like a screw long & blades r long.. thin curved almost feather light metal that bends a little in water to match wash & speeds. Not 2 inline props 1ft' ish apart but 1 long screw like prop & shaft. Lose is high but bc u hve long.. shaft like twisty thin prop that flexes in pitch in water u get most spin & most push for least load on motor just screwing in.
You briefly talked about the electric propulsion consumption at a few RPM's & speed. However, did not advise us the battery bank capacity, so we or you could advise how long one could run on full electric at those RPM's/speed. Good video other than that.
I have forgotten the exact capacity now but it did have the upgraded hybrid pack which gave you the more powerful motors and biggest lithium available at the time. It may have been 600AH of lithium but don't hold me to that. 4-5 kts seems to be the best speed under electric as WOT on electric really sucks the juice. I mention the amps i'm consuming in the video from memory
@@theboatbrokerage, I think you mentioned how much at four or five knots, but not at seven. I’ll go watch again to be sure. And yes, Amps would tell me the answer I’m after with a bit of math and a check to see how many Volts the motor runs at (48, I think).
There is a advance prop design for max speed at med speeds 35+ thru 50 knots. It is 3 blade holes but the pitch of the blades is < 2 n 1 > deal. Meaning starts out cleanest pitch at widest prt of blade then has more cut & another blade at thinnest prt of each blade. A 6 blades on a 3 blade prop. U put 2 diff blades w/diff pitches & widths together. Stats out 3 & turns into 6 & two diff props, but still hving holes at wide prt of blade & still in line 2 prop design. 2 or 3 blade in most every case beats 4, or 5 blade prop not twin inline every time. Nuke massive carrier or oil tanker size vessels the working speed determines the best blade count. At the carrier size & speed both max working range 4 & 4 or 5 & 5 might give slightly better top end then 3 & 3 but at greater fuel burn. U just can't beat 2 & 2 or 3 & 3 as best blade count inline, other than hving adjustable pitch add or advanced 3 turns into 6 two in 1 pitch blade design. The hole is key to getting least drag to least spin lowest rev fuel save for inline design.
Probably not recommended, but how long would it take to sail from California to Japan in the fully electric 40? What would be the dangers of making that trip in this vessel?
Yes i'm afraid both not recommended and not possible. This boat is just not designed for that kind of a journey. Something like the Nordhavn 40 would be more suited to that trip in a similar sized motor boat.
Are there hybrid boats like these that can be modified to travel long distances in rougher waters for long periods of time, not just for leisure boating? Thanks for this video by the way!
Hi Kamin, from what we have seen so far the honest answer is no. There are many experimental boats doing long distance journeys but the technology is not at the stage of mass market production for long distance at this time. I think we will see sailing yachts achieve this first using solar and re-generation while under sail and then we should see some very large motor yachts experimenting with this technology before it filters down to the mass market. Because of the high drag in water it is a big challenge to overcome. We may even see new fuels like hydrogen one day take over petrol and diesel..?
@@danielbrown7231 Thanks! I've seen some videos on them. Unfortunately they are still very expensive. If only some of them were within reach for the average joe that would be great. :)
The more pitch the more screw like faster prop will spin but less weight it will move bc just no load. The flatter the pitch the less sped but more weight push. W/out right pitch sped or load it will b slow> off the line. Max speed design 1 of the 2 props will be larger than the other giving u a . But still must get the diameter of the prop to match size of boat/weight to the normal best rev range of motor. Then 3 blades 2 props inline either studded or holed to fine tune whether fuel saving or best med speed performance. Adjustable pitch is huge or advanced prop 2 blades & pitches in 1 blade is best of all, so long as 2 props inline.
The other thing u can do if if using 2 or 3 shafts U can off center the prop on the right & left shaft & perfect center the prop on the center shaft. So right engine gives u less right push & left engine gives u less left push, so it naturally wants to track straight even though wash of prop & load on left & right shaft engines r less than center engine & shaft. Only in V shaped hulls but in cats hulls no diff of load left or right & they naturally r more bal.
I guess I'm not clear on the idiomatic use of "just here" in this video. Anyone from down under care to explain that phrasing to me? Does it imply convenience of the location? Is it sort of like the US English, "It's right here", connotating something obvious you may have missed? It does not appear to mean, "just here but/and nowhere else". Correct?
@@theboatbrokerage Idiomatic usage / connotation of a word or phrase is divorced from its literal definition and can vary greatly by culture, even among those who speak the same language. The difference in idiomatic words and phrases between cultures, even speaking the same language (especially those who speak it as a second language), can be vast, sometimes confusing, often embarrassing. Idiom is *almost* synonymous colloquially with "slang", but not precisely the same thing. Slang is not always idiomatic. For instance, a non-native speaker might not understand why a couple of guys in the crowd snicker if he asked, "Is Raquetball always played with blue balls?" (For all I know, you might not, maybe this is a US idiom.) Or might not understand that saying, "Man that guy is on fire tonight", is no a cause for alarm. The above is the case even though all speakers could write down the correct definition of all of the words used. "That woman is really fit." = In the UK this is an idiomatic phrase that could mean, in fact most likely means, "That woman is really attractive." "That woman is really fit." = In the USA this phrase ONLY EVER refers to her state of health and physical fitness, NEVER her attractiveness. Not only that, if two men were having a conversation discussing a woman in sight they might not even realize that while they agree with the utterance they are not even discussing the same characteristic. Confusion could arrive if the bloke likes women a little round and curvy. Then the dude, who also likes rounder women, might answer the bloke, "Well, I mean she's smoking (an idiom in its own right), but, bro, I don't think she's worked out a day in her life, she probably gets winded walking up a flight of stairs." The above is the case even though the actual *definition* of "fit" is exactly the same in both cultures. That guy just left. = That guy recently left. This is just what I need. = This is exactly what I need. This boat amenity / feature is *just* here (said almost every single time something is introduced). = ??? Yes, I'm a linguistics nerd. Love the walkthrough though! Thanks.
In most boats normal V hull not speed class non outboard, a cleanest pitch best lights metal twin 3 blade prop about 1ft apart is best poss seat-up w/holes each blade bigger to smaller in diameter depending on spec/power of the motor. Ie the bigger the prop the cleaner the pitch w/perfect diameter hole per prop will give the best fuel in largest chop sea range. More speed a 2 blade prop largest poss right sized hole to engine power. For outboard a 2 adjustable prop pitch. Or 2 props inline studded diff pitch if not adjustable w/lightest poss plastic material. Ideally if not adjustable the studded diff pitch then main props The front pitch of leading prop will b diff then trailing pitch. BC small fast spinning props waste/lose a lot in wash so the trailing prop needs More cutting pitch then leading to catch more wash.
She's sold now Bhatt but feel free to send me an email enquiries@theboatbrokerage.com and i'll flick you the price. I don't discussing pricing on social media that's why. Cheers
I'm really liking this boat over the 39 Hybrid more each time I see it. I would like to see more solar in lieu of the sunroof on the top, and something done with that opening hatch in the 2nd cabin. I really hate that thing. You kinda skipped completely over it in your video, but it is completely useless in my opinion. The dingy davit system looked really cool on this boat as well.
G'day Charlie, i see your points however i would say that the sunroof is pretty essential to let some air through the cabin.. I actually delivered this boat to the new owners yesterday in Melbourne and his kids went straight to that cabin and opened the sliding hatch and started playing and having a real laugh.. i'm no expert but it seemed to work for the little tackas. Dinghy davit system is choice. I love it and can't think of a better solution considering you have solar roof. Thanks for your feedback, i enjoy getting everyone's opinion
@@theboatbrokerage so one customer liked it and all of a sudden it must be on every boat? Not a very good argument. Kids also go for anything they can use their imagination to play on or with. The truth is that skylight will be covered up by pretty much everyone buying the boat, because a cabin is supposed to be private, and opening it up to the cockpit removes that privacy. I think I'm referring to the correct sliding hatch.
This is a really great, informative walk through, so much better than most - great job. I hear they have a new 6th generation hybrid system coming in this now, any idea what has changed?
flat seas & pushing force is far less than light to med chop seas. In heavy seas u need all the pushing prop u can get sped is not happening any way. So if lake boat the push load normal seas is very diff from day tripper vs off shore. Med boat diff than north Atlantic off shore push load. A sub at 300 ft or so very diff push load than 300 meters.
Diesel hve lower rev range but critcal to get best out of lower range but diff between newer motor & older motor is less an issue, but gas or out board performance fuel lower ideal sweet rev range is nothing compared to longer life motor loading, HUGE cost!
Ie if u get fuel rev dialed in perfect load sea normal range u r most likely over taxing motor. Better to shot for 85% fuel push load max spin working normal seas range & long term durability, or your a racer buying new outboard every race or 2 & don't care.
Hi Paul, SHe's actually sold and i've been busy training the new owners how to operate the boat. keep an eye on our website www.theboatbrokerage.com.au for any future listings like this
Electric can match the speed of rev shaft spin sure & hve good torque but unless tiny gas motor & large electric motor no way they r going to match up close enough to use same shaft & prop.
Hi Paul, this boat was listed for $1M Australian Dollars. I'm happy to exchange an email if it's something you're interested in second hand when the owner is ready to upgrade. my email is dan@theboatbrokerage.com and the Greenline Yachts website is best to use when searching for local dealers www.greenlinehybrid.com/en Good luck these are top boats.
My twin prop per shaft only 3 blade less drag more strength then 4,or 5 blade is where the non pod market will b going. 3 blade props r cheaper meaning u can use better metal instead of more blades. The pitch bs becomes less a factor & u stay more in the most efficient pitch range, again making prop more standardized meaning cheaper. { U want lowest rev load on engine thru the useful speed range under full sea chop conditions not out board max spin rate.} By hving to props inline 1ft apart & either drilling holes or studing hole to give smaller mini blade diff pitch deal to basic cleanest flat pitch. Or u drill holes center of each blade so to lessen rev load, to hve quick hole shot, & fine tune the prop cleanest flat pitch biggest size prop yet like hving 6 blades at 3 strong cheap prop cost. What 1 prop spins off wash vortex the other trailing prop cleans up(more power less load & less speedy vortex loss. The 3rd trick is a studed hole per blade on smaller fast spinning props rather than hole that is a net Cutting blade for each prop blade. Could a 5 & 5 big boat set up hve 3 holes each blade & 2 Cutting blade studs, sure*^
I have to say this guy Dan does great reviews ... If you want to lock the kids away.... easy to dock without asking your numb nuts mates ....lol cracked me up what a down to earth but funny n knowledgable guy
Very very interesting, thanks Dan! I noted a consumption of 70 A at 4.5 knots and 110 A at 5 knots... I am also interested in knowing the consumption at 3 knots, 4 knots, 6 knotsand 7 knots, to have a complete picture. Thank you so much. I would also be interested to know at which speed the boat is energy self-sufficient with its solar panels. For information, in 2013 a video from Greenline France (*) indicated 3.8 knots, according to tests on a lake for 5 hours (where the battery charge remained constant). Over the past 10 years, electric motors have probably improved and so have solar panels... Hence my question for 2023 model. * : "Nauticales 2013 - GreenLine 40, the hybrid of success" on ua-cam.com/video/SWuuPEC1qgE/v-deo.html
I suspect she would drag her bum a bit with extra HP. The underwater profile of the 39 would likely benefit from a HP increase but i don't see the 40 benefiting from it. You'd probably just burn more fuel for the same result.
Get yourself a new cameraman that will focus on the items you are describing and not you !!! Or even better grab the camera and show us what you are highlighting !!!
Excellent very detailed review, thank you!! This is a fine and very interesting boat ! this is one of the few boats of this length still powered with shaft-drive! (I am really tired of my stern drives so fragile, not reliable and expensive to maintain). I have a very important question if possible: rough
The question is if you have any idea of the sea keeping capabilities! I ask because this seems more like a fresh water boat and the hull is completely flat. Have you have tested the boat in rough sea or do you have or know any footing in rough sea? Thank you again!
Hi Andrea, Great i'm happy to hear you found this usefull! Yes i've driven multiple GL40's offshore in both up and downwind conditions varying from 1 - 2m swells with both short and long wave periods. The round bilge would be very rolly if it wasn't for the stabilizer fins. These give what is a pretty light hull some directional stability which makes it comfortable and managable in a following sea and less rolly if the swell is on your beam. Upwind if you have her trimmed down and drive at the appropriate speeds she's fine but it is wet so you definately want the 3 sets of windscreen wipers and not the standard one set the boat came with. As a coastal cruiser this hull is fine if you do all the normal things and plan around weather etc. It's not an ocean crossing hull and it doesn't perform as well upwind compared to say a Grand Banks 42 which is heavier and has a keel however it's quicker and faster to manouver at the dock so there is pro's and cons. Hope this was usefull?
@@theboatbrokerage Thank you very much for the reply! Very helpful and it makes sense. On the other end a flat hull, large beam and the 2 stabilizer fins should make this boat more stable at anchor ? (less rolling).
@@adedomini no worries. Yeah I find she rolls normally as a wave passes underneath but the fins kick in and stabilise it very quickly so no tendency to bob around like some round bilges
"... without having to involve some of your numbnut mates." Possibly the best line in a boat review I've ever heard!
yeah that one just kinda slipped out, but glad you liked it!
That how we Aussies talk mate lol 🤣

@@theboatbrokerage about being taken seriously, they are kinda curious how a 74 year old can ride one. Practice makes better.

love greenlines. gorgeous.

As you go through the speed and rpm, I would love to know the estimated range
How many more years will it take before most shipyards develop an all electric model yacht? Noise and diesel fuel reduction seems like next level goals, customers can appreciate.
They are already available. Range and cost is the current problem which has not been solved.

Would the power and efficiency be different if the shaft propeller was driven by a an electric motor powered by diesel generator or the shaft propeller powered by a straight diesel engine?
No i don't think you would see much difference as you still come up against hull speed with a design like this.

Agreed!
A good prop to a boat is like snow tires to a car, or racing slicks.
So in the middle special end of the scale a good prop best metal working sea & best pitch sized diameter for load either holed or studded fine tuned 85% efficient if working not racing motor can hve
Great review, Is there a fully electric version of this Greenline 40 for review?
Not in Australia. Maybe some of the Euro lakes have fully electric boats? We still love our fossil fuels down here
You’d be better off sailing, it’s only capable of cruise speed 4-5kn over time.
Very nice boat ❤️👍🤩
Thank you! Cheers!
Nice boat!! How many meters are? And what is the price? Please! Thanks. Really nice!! ❤️👍😊
I had to laugh at some of Dans comments especially in regards to the cockpits opening door NUMB NUFF mates .. ha ha ha
I forget the camera is rolling sometimes lol
@@theboatbrokerage it shows personality and thats what everybody likes... doing a great job Dan!
Using same shaft same prop makes sense if diesel & hybrid bc both torque heavy but if gas & hybrid a completely diff pitch & prop would b needed.
W/out any width of prop & no load high pitch u can't get off the line problem, all 5th gear set-up needing long runway.
If over 80 knots power racing the shaft is like a screw long & blades r long.. thin curved almost feather light metal that bends a little in water to match wash & speeds. Not 2 inline props 1ft' ish apart but 1 long screw like prop & shaft. Lose is high but bc u hve long.. shaft like twisty thin prop that flexes in pitch in water u get most spin & most push for least load on motor just screwing in.
You briefly talked about the electric propulsion consumption at a few RPM's & speed. However, did not advise us the battery bank capacity, so we or you could advise how long one could run on full electric at those RPM's/speed. Good video other than that.
I have forgotten the exact capacity now but it did have the upgraded hybrid pack which gave you the more powerful motors and biggest lithium available at the time. It may have been 600AH of lithium but don't hold me to that. 4-5 kts seems to be the best speed under electric as WOT on electric really sucks the juice. I mention the amps i'm consuming in the video from memory
Great tour. Thank you very much. How many kW was the electric motor drawing at that seven knot cruise?
It uses heaps at 7kts but i think i mentioned the number of Amps we were consuming at 7kts in the video, hopefully that helps?
@@theboatbrokerage, I think you mentioned how much at four or five knots, but not at seven. I’ll go watch again to be sure. And yes, Amps would tell me the answer I’m after with a bit of math and a check to see how many Volts the motor runs at (48, I think).
There is a advance prop design for max speed at med speeds 35+ thru 50 knots. It is 3 blade holes but the pitch of the blades is < 2 n 1 > deal. Meaning starts out cleanest pitch at widest prt of blade then has more cut & another blade at thinnest prt of each blade. A 6 blades on a 3 blade prop. U put 2 diff blades w/diff pitches & widths together. Stats out 3 & turns into 6 & two diff props, but still hving holes at wide prt of blade & still in line 2 prop design. 2 or 3 blade in most every case beats 4, or 5 blade prop not twin inline every time. Nuke massive carrier or oil tanker size vessels the working speed determines the best blade count. At the carrier size & speed both max working range 4 & 4 or 5 & 5 might give slightly better top end then 3 & 3 but at greater fuel burn. U just can't beat 2 & 2 or 3 & 3 as best blade count inline, other than hving adjustable pitch add or advanced 3 turns into 6 two in 1 pitch blade design. The hole is key to getting least drag to least spin lowest rev fuel save for inline design.
Hmmm🤔, where do we put our legs when the dinner table converts to a coffee table???
First it was a 36, then it became a 39 and now it's the Greenline 40.
Probably not recommended, but how long would it take to sail from California to Japan in the fully electric 40? What would be the dangers of making that trip in this vessel?
Yes i'm afraid both not recommended and not possible. This boat is just not designed for that kind of a journey. Something like the Nordhavn 40 would be more suited to that trip in a similar sized motor boat.
@@theboatbrokerage thanks. Guess I'll keep looking.
Are there hybrid boats like these that can be modified to travel long distances in rougher waters for long periods of time, not just for leisure boating? Thanks for this video by the way!
Hi Kamin, from what we have seen so far the honest answer is no. There are many experimental boats doing long distance journeys but the technology is not at the stage of mass market production for long distance at this time. I think we will see sailing yachts achieve this first using solar and re-generation while under sail and then we should see some very large motor yachts experimenting with this technology before it filters down to the mass market.
Because of the high drag in water it is a big challenge to overcome. We may even see new fuels like hydrogen one day take over petrol and diesel..?
@@theboatbrokerage Thanks for the info! I’ll keep watching as the tech evolves on these boats
check out Silent Yachts its the closest thing that i know of. They already crossed the atlantic with one.
@@danielbrown7231 Thanks! I've seen some videos on them. Unfortunately they are still very expensive. If only some of them were within reach for the average joe that would be great. :)
@@cavemanabc NONE of these boats are within reach of the “average joe”
Could you cross the Atlantic with it?
The more pitch the more screw like faster prop will spin but less weight it will move bc just no load. The flatter the pitch the less sped but more weight push. W/out right pitch sped or load it will b slow> off the line. Max speed design 1 of the 2 props will be larger than the other giving u a . But still must get the diameter of the prop to match size of boat/weight to the normal best rev range of motor. Then 3 blades 2 props inline either studded or holed to fine tune whether fuel saving or best med speed performance. Adjustable pitch is huge or advanced prop 2 blades & pitches in 1 blade is best of all, so long as 2 props inline.
The other thing u can do if if using 2 or 3 shafts U can off center the prop on the right & left shaft & perfect center the prop on the center shaft. So right engine gives u less right push & left engine gives u less left push, so it naturally wants to track straight even though wash of prop & load on left & right shaft engines r less than center engine & shaft. Only in V shaped hulls but in cats hulls no diff of load left or right & they naturally r more bal.
I guess I'm not clear on the idiomatic use of "just here" in this video. Anyone from down under care to explain that phrasing to me? Does it imply convenience of the location? Is it sort of like the US English, "It's right here", connotating something obvious you may have missed? It does not appear to mean, "just here but/and nowhere else". Correct?
I don't know what idiomatic means so we are both confused now :)
@@theboatbrokerage Idiomatic usage / connotation of a word or phrase is divorced from its literal definition and can vary greatly by culture, even among those who speak the same language. The difference in idiomatic words and phrases between cultures, even speaking the same language (especially those who speak it as a second language), can be vast, sometimes confusing, often embarrassing.
Idiom is *almost* synonymous colloquially with "slang", but not precisely the same thing. Slang is not always idiomatic.
For instance, a non-native speaker might not understand why a couple of guys in the crowd snicker if he asked, "Is Raquetball always played with blue balls?" (For all I know, you might not, maybe this is a US idiom.) Or might not understand that saying, "Man that guy is on fire tonight", is no a cause for alarm. The above is the case even though all speakers could write down the correct definition of all of the words used.
"That woman is really fit." = In the UK this is an idiomatic phrase that could mean, in fact most likely means, "That woman is really attractive."
"That woman is really fit." = In the USA this phrase ONLY EVER refers to her state of health and physical fitness, NEVER her attractiveness. Not only that, if two men were having a conversation discussing a woman in sight they might not even realize that while they agree with the utterance they are not even discussing the same characteristic. Confusion could arrive if the bloke likes women a little round and curvy. Then the dude, who also likes rounder women, might answer the bloke, "Well, I mean she's smoking (an idiom in its own right), but, bro, I don't think she's worked out a day in her life, she probably gets winded walking up a flight of stairs."
The above is the case even though the actual *definition* of "fit" is exactly the same in both cultures.
That guy just left. = That guy recently left.
This is just what I need. = This is exactly what I need.
This boat amenity / feature is *just* here (said almost every single time something is introduced). = ???
Yes, I'm a linguistics nerd. Love the walkthrough though! Thanks.
In most boats normal V hull not speed class non outboard, a cleanest pitch best lights metal twin 3 blade prop about 1ft apart is best poss seat-up w/holes each blade bigger to smaller in diameter depending on spec/power of the motor. Ie the bigger the prop the cleaner the pitch w/perfect diameter hole per prop will give the best fuel in largest chop sea range. More speed a 2 blade prop largest poss right sized hole to engine power. For outboard a 2 adjustable prop pitch. Or 2 props inline studded diff pitch if not adjustable w/lightest poss plastic material. Ideally if not adjustable the studded diff pitch then main props The front pitch of leading prop will b diff then trailing pitch. BC small fast spinning props waste/lose a lot in wash so the trailing prop needs More cutting pitch then leading to catch more wash.
Less or least load for range normal sea range is not just fuel deal but on older motors may b a must longer life.
What was the price for this beautiful family boat.
She's sold now Bhatt but feel free to send me an email enquiries@theboatbrokerage.com and i'll flick you the price. I don't discussing pricing on social media that's why. Cheers
Very nice.
Excellent boatTEST
Thankyou!
Do these have features like skyhook or joy stick driving?
Hi Don, no joystick on the GL40 but you can have this on the GL45 which comes with either shaft drive or IPS as an option.
Thanks
No problem
I'm really liking this boat over the 39 Hybrid more each time I see it. I would like to see more solar in lieu of the sunroof on the top, and something done with that opening hatch in the 2nd cabin. I really hate that thing. You kinda skipped completely over it in your video, but it is completely useless in my opinion.
The dingy davit system looked really cool on this boat as well.
G'day Charlie, i see your points however i would say that the sunroof is pretty essential to let some air through the cabin..
I actually delivered this boat to the new owners yesterday in Melbourne and his kids went straight to that cabin and opened the sliding hatch and started playing and having a real laugh.. i'm no expert but it seemed to work for the little tackas.
Dinghy davit system is choice. I love it and can't think of a better solution considering you have solar roof.
Thanks for your feedback, i enjoy getting everyone's opinion
@@theboatbrokerage so one customer liked it and all of a sudden it must be on every boat? Not a very good argument. Kids also go for anything they can use their imagination to play on or with. The truth is that skylight will be covered up by pretty much everyone buying the boat, because a cabin is supposed to be private, and opening it up to the cockpit removes that privacy.
I think I'm referring to the correct sliding hatch.
This is a really great, informative walk through, so much better than most - great job.
I hear they have a new 6th generation hybrid system coming in this now, any idea what has changed?
flat seas & pushing force is far less than light to med chop seas. In heavy seas u need all the pushing prop u can get sped is not happening any way. So if lake boat the push load normal seas is very diff from day tripper vs off shore. Med boat diff than north Atlantic off shore push load. A sub at 300 ft or so very diff push load than 300 meters.
Diesel hve lower rev range but critcal to get best out of lower range but diff between newer motor & older motor is less an issue, but gas or out board performance fuel lower ideal sweet rev range is nothing compared to longer life motor loading, HUGE cost!
Ie if u get fuel rev dialed in perfect load sea normal range u r most likely over taxing motor. Better to shot for 85% fuel push load max spin working normal seas range & long term durability, or your a racer buying new outboard every race or 2 & don't care.
So why do I have to watch a commercial and skip the ad to watch a half hour commercial about a boat?
You don't... ;)
Price?
Hi mate, how much for that boat?
Hi Paul, SHe's actually sold and i've been busy training the new owners how to operate the boat. keep an eye on our website www.theboatbrokerage.com.au for any future listings like this
Electric can match the speed of rev shaft spin sure & hve good torque but unless tiny gas motor & large electric motor no way they r going to match up close enough to use same shaft & prop.
How much is this? Is there a dealer in Philadelphia?
Hi Paul, this boat was listed for $1M Australian Dollars. I'm happy to exchange an email if it's something you're interested in second hand when the owner is ready to upgrade. my email is dan@theboatbrokerage.com and the Greenline Yachts website is best to use when searching for local dealers www.greenlinehybrid.com/en
Good luck these are top boats.
FYI it's Dan Jones responding from my other UA-cam channel. I'm the guy in the video from The Boat Brokerage.
My twin prop per shaft only 3 blade less drag more strength then 4,or 5 blade is where the non pod market will b going. 3 blade props r cheaper meaning u can use better metal instead of more blades. The pitch bs becomes less a factor & u stay more in the most efficient pitch range, again making prop more standardized meaning cheaper. { U want lowest rev load on engine thru the useful speed range under full sea chop conditions not out board max spin rate.} By hving to props inline 1ft apart & either drilling holes or studing hole to give smaller mini blade diff pitch deal to basic cleanest flat pitch. Or u drill holes center of each blade so to lessen rev load, to hve quick hole shot, & fine tune the prop cleanest flat pitch biggest size prop yet like hving 6 blades at 3 strong cheap prop cost. What 1 prop spins off wash vortex the other trailing prop cleans up(more power less load & less speedy vortex loss. The 3rd trick is a studed hole per blade on smaller fast spinning props rather than hole that is a net Cutting blade for each prop blade. Could a 5 & 5 big boat set up hve 3 holes each blade & 2 Cutting blade studs, sure*^
I have to say this guy Dan does great reviews ... If you want to lock the kids away.... easy to dock without asking your numb nuts mates ....lol cracked me up what a down to earth but funny n knowledgable guy
Haha thanks for the feedback!
Very very interesting, thanks Dan!
I noted a consumption of 70 A at 4.5 knots and 110 A at 5 knots... I am also interested in knowing the consumption at 3 knots, 4 knots, 6 knotsand 7 knots, to have a complete picture. Thank you so much.
I would also be interested to know at which speed the boat is energy self-sufficient with its solar panels. For information, in 2013 a video from Greenline France (*) indicated 3.8 knots, according to tests on a lake for 5 hours (where the battery charge remained constant).
Over the past 10 years, electric motors have probably improved and so have solar panels... Hence my question for 2023 model.

Dan you should start your own YT channel…wait….😊
haha... done. No more boat sales for me
Awesome boat…filthy windshield
It is a great boat - thanks for the feedback
Beauty ! Never really looked at Greenlines till this video opened my eyes.
Good to hear. They are a great looking boat and the finish is up there with the major brands
This boat in water at speedy cruse & front bow proud of water screams out for front hydrofoils just right & left & feet ft' back from bow.
'Coffee table' if you have no legs - bed infill to everyone else.
Haha yes.. but the table unbolts and moves so can be a coffee table too
That refrigerator looks like crap lmao
Personal choice i guess, i can say it chills beers as one would expect. Thanks for the feedback
It's just missing more range
Show more boat, less moderator next time pls!
Copy that. We were trying to show more boat but perhaps not enough.
aaa jebate takvi test, nisi nista reka o bateriji, 120A a koliko kW potrosnje?? Vjerojatno 20 minuta voznje za 200 000 dolara
This boat need 2x Volvo 300
I suspect she would drag her bum a bit with extra HP. The underwater profile of the 39 would likely benefit from a HP increase but i don't see the 40 benefiting from it. You'd probably just burn more fuel for the same result.
@@theboatbrokerage maybe you right about drag.. but i will like to see more HP and some zipwake, i think she perform better :)

WTF? 45L/h for 23kph? What a waste, sorry. And 90l/h for 36kph? WOW.
They are losing the “green” idea
Not a coffee table
It actually is both a coffee table when down and support for the day bed. Thanks for watching
@@theboatbrokerage
Does the table move away from the couch? In the lowered position it appeared to be tight against the couch..
@@GENECARP yes I probably should have mentioned that. It unbolts from the floor so you can move it around

Excellent very detailed review, thank you!!
This is a fine and very interesting boat ! this is one of the few boats of this length still powered with shaft-drive! (I am really tired of my stern drives so fragile, not reliable and expensive to maintain).
I have a very important question if possible:
rough
The question is if you have any idea of the sea keeping capabilities! I ask because this seems more like a fresh water boat and the hull is completely flat. Have you have tested the boat in rough sea or do you have or know any footing in rough sea? Thank you again!
Hi Andrea,
Great i'm happy to hear you found this usefull! Yes i've driven multiple GL40's offshore in both up and downwind conditions varying from 1 - 2m swells with both short and long wave periods.
The round bilge would be very rolly if it wasn't for the stabilizer fins. These give what is a pretty light hull some directional stability which makes it comfortable and managable in a following sea and less rolly if the swell is on your beam. Upwind if you have her trimmed down and drive at the appropriate speeds she's fine but it is wet so you definately want the 3 sets of windscreen wipers and not the standard one set the boat came with.
As a coastal cruiser this hull is fine if you do all the normal things and plan around weather etc. It's not an ocean crossing hull and it doesn't perform as well upwind compared to say a Grand Banks 42 which is heavier and has a keel however it's quicker and faster to manouver at the dock so there is pro's and cons.
Hope this was usefull?
@@theboatbrokerage Thank you very much for the reply! Very helpful and it makes sense.
On the other end a flat hull, large beam and the 2 stabilizer fins should make this boat more stable at anchor ? (less rolling).
@@adedomini no worries. Yeah I find she rolls normally as a wave passes underneath but the fins kick in and stabilise it very quickly so no tendency to bob around like some round bilges
@@BoatLife_DansBoatLife ok thank you! So at anchor she would roll or be as stable as "normal" boat of the same size....
