Gilbert Caroff Super Disko Steel Expedition sailboat with electric motors! Report 20
VloĆŸit
- Äas pĆidĂĄn 1. 06. 2023
- We have shown bits and pieces of Hakluyt in previous videos - but here is the overview of Hakluyt's main features. Hakluyt is quite different from standard production sailboats in many ways - not only because of her electric motors but her original design incorporated notable features so she was ready for polar regions. She is a mix between a live aboard and expedition style sailboat leaning more towards the expedition style boat. We define "expedition" style sailing as that which allows more storage and off-grid capabilities enabling us to spend longer periods of time in more isolated and remote places without having to stock up on food, gas, or water.
Hakluyt was built in Chantier Brument, France. She is a steel, 47 foot "Super Disko" whose design was drafted by renowned French Naval architect Gilbert Caroff. She has a noticeable steep raked bow designed for riding up and over low icebergs or growlers (larger submerged chunks of ice) and has a shallow draft with a lifting keel to provide safety and maneuverability in arctic regions where ice flows often force boats to shallower waters. Her flat bottom belly allows Hakluyt to be easily beached in emergencies or when the opportunity presents itself. Her accommodations and interior are built for expeditionary work and field research. This isn't really a "pleasure craft" in the conventional nautical sense, but a working expedition vessel!

Awesome. Competing with Alluring Artic for favorite Adventure Sailing. I expect yous to go viral on one of these days. âïžâ€ïžâïžđđđżđŠđŠđș
Wow! Thanks Eugenio! This is the best compliment ever!đ
Totally impressive setup, well done. I enjoy your adventures and impressed that it includes 3 dogs. Thanks
Thanks DreamTime!!!
Hi guys,
I have an electric yacht 30 kw liquid cooled system on a 42' Brewer. Replaced a 30,000 hour 90 HP Lehman. Can't say enough about quiet and reliability of the electric. You mentioned hoping for Regen. Our experience is Regen is about 25% of what you could consume at say 1,200 rpm can be generated at just under hull speed. I've also heard for the electric yacht you need at least a 19 " prop.
So, our 600 watts of solar charges house batteries. Alas our biggest issue is "refilling" the batteries. I have two generators. One a Honda 2200i, which puts out 1,800 watts DC after losses through the inverter/charger. Second generator seems to have solved issue. My solution is a small Chinese "range extender" DC generator. It's quiet and puts out 4 to 5 kw, enough to keep us going at 5 knots for as long as the fuel (gas) lasts. So, not renewable, but reliable and minimal maintenance. I converted old diesel tanks and have 100 gals capacity.
We went to Nova Scotia last summer from Rhode island. Maybe as far as Cape Breton this July/Aug. Essentially extended costal sea trials in advance of bigger dreams.
Hi Bruce! Great to hear about your electric boat and experiences with regeneration!! Oceanvolt attempted to adjust the pitch of the props for regen but still no go (the props are a fixed size unfortunately - tuned to their system)... We now are being told we have to convert the system to "torque" mode from "RPM" mode - but that requires a few other hurdles to convert. Our fingers are crossed that will work!
Interesting to hear about your dual generator solution! We do have a small 2kw generator onboard but we use it only as a crutch in those "we better have more juice" situations and don't rely on it as a hybridized solution per se. Your set up sounds awesome and I hope we get the chance to compare notes! Super cool to know there is another monohull out there with a 30kw electric motor!! Sweet! We will be in Cape Breton for a bit - better yet - hopefully we can meet up!! Cheers!
@@hakluytsadventures Its a rainy day here in VT, so I'm at my computer.
Hope OV's torque from RPM shift works. You are not the only one I've heard about with issues with OV systems.
Here is a bit of a rainy day download, for what it's worth to you.
My point is that even with any regen, its contribution is de minimis compared to what you know you consume by running say at even 50% of hull speed. I'd say if one was not coastal sailing - just tradewinds cruising - then sailing vs motor time is such that regen could bring you back up to full SOC over a few days and keep you there for house needs.
For coastal work, where you anchor at night (i.e., don't want to listen to a generator) or have a high motor to sail ratio (just think how much juice you can use setting an anchor or pushing against a current, trying to get to anchorage to meet folks, bucking a headwind/chop, etc.) motoring is best done from a full battery as you'll want reserve for maneuvering in harbor. After your day's electric motor use, you'll be at a lower SOC. You'll do some combo of wait for wind/solar to recharge, wait to run your generator while next sailing (noise less of an issue), hope your sailing is fast enough for regen or know that the next day you'll be ashore and can leave your generator so your neighbors won't forget you (ha, ha, ha). The whole thing a bit of a juggling act with uncertainty.
So, here is my logic towards my solution, which I'll be testing this summer. In the "olden days", when under way, one ran the noise (the diesel) whilst not sailing (and hopefully not more, but as we recall, many ran/run diesels as generators longer than necessary for motoring to keep the house batteries charged). Typically this diesel to required motoring ratio was one to one, especially for coastal work. But recall CZcamsrs Sophie and Ryan who had to run their engine a fair bit while crossing from Africa to Antilles - a full trade wind run.
Now moving to today's technology - electric drives. The challenge is to generate juice to meet your needs. In your case with the 1k solar, .8k wind and possible regen, you could make the generator to motoring time ratio be less than one. For me, the Honda 2,200i did not cut it (1,800 watts) plus any regen (maybe 1.5kW when at nearly hull speed), 640W solar (maybe 3k watts per day (600 watts x ~5 hrs good sun per day)) as my rpm/watts/knots equation means 1,800 watts (assume solar covers my house needs and regen is not happening on a day when you really have to motor so both get dropped from my equation) pushes my Brewer at at best 3 knots (smooth water) meaning almost 2x generator to motoring time. This sucked (fuel transfers, noise, moving the generator in and out of its locker). As an aside, an interesting solution was to hook up the dinghy to the stern and run our 15 hp Tohatsu at fast idle forward making big boat go consistently 3.5 knots as long as there was fuel - interestingly a very efficient set up . . . I can review the set up that worked in any seas if you want.
Part of my cosey winter was spent researching and buying (took a two tries to find one) a "range extender" DC generator from our friends in China that puts out 5kW DC (losses of 2 kW through the rectifier as it is rated at 7kW AC) and is smaller than the Honda 2,200i. The damn thing runs like a charm, isn't that noisy, produces plenty of waste heat for recapture into the cabin . . . . and puts out enough juice to match my consumption while motoring at a reasonable speed (4.8 knots, smooth water). Luckily for me I had space in my old engine room to build a shelf for this generator and piped the exhaust outside. Delivered it was just under $1k US. Further, in a pinch, I can run the Honda and the range extender simultaneously.
Any philosophy aside, with my practical solutions hat on here, I'm guessing a downside for you is where you'd put something like this as it looks like your old engine room is occupied by OV controls and you removed its enclosure to make room for all important toys. You'd want a dedicated space to keep a generator covered and noise insulated - here's my unsolicited suggestion: you could build a portable "dog house" up front and probably not even know the generator was running while you were sailing given your sweet dodger/aft cockpit configuration. Happy to send details on my install if you are interested.
Best to you both and the dogs (that's your heat source, isn't it?). Loved the winter scenes in the resettled community that "hosted" you along south coast of NF.
Regarding the south coast of NS. We found it to be a joy in the summer, especially later (August) when fog is gone and SW "trades" are less frequent (you'll be heading west?). Know we had some days in July of nearly 100% fog and highs in the upper 50s while only a few miles offshore. Other days sunny with amazing sailing, seeing few if any commercial or recreational vessels. Once into almost any harbor, it clears and warms and the folks on shore are sooo nice. Not sure of your schedule, but a highlight for us was the Pride parade in Halifax - sometime around July 22. Anchor in Northwest arm and get a ride into town.
Indeed, maybe we'll cross paths this summer. I'll keep an eye on your AIS location.
â@@hakluytsadventuresOur home base for our Corbin 39 "Simmerdim" is St. Peter's. Maybe see you out there.
@@brucegenereaux Bruce! Thanks for the reply, feedback and comments! Your range extender sounds like a really good solution! Strong work! We do well recuperating what we use on a daily basis while adding a few extra electrons to the system bank - well... when the sun shines that is! With 2kw of bifacial solar we do well - if we had 3kw of bifacial solar I think all three legs of our charging stool would be super solid. Alas - where to put 1 more kw of panels however...
In any event - LOVING Nova Scotia and the Bras D'or lakes - it's nice to take a bit of a break from the North Atlantic for a spell!! Cheers!
@@jonathanmau4822 That sounds great! We will be in St Peter's in a week or so! Cheers!
Just binge watched all your videos. I hope one day to do some similar sailing. You do a good job at capturing "real sailing". Very interested to see how going a 100% electric drive pans out. One minor criticism is I think your music choices & vol is a bit "heavy handed"( Overpowering). Some great mooring locations though. đ
Hi guys , iâve just watched your video And loving the idea of going 100% electric. I am in contact with Wayne Peters from Ocean Volt . Iâm thinking about the same setup as you have just smaller. Iâm looking to purchase an island trader 38, which I intend to sail singlehanded from Portsmouth UK, around Ireland up the West Coast of Britain, up to the Faroe islands then Iceland, and Greenland before going down for Antarctica. But the issues that you guys seem to be having with regeneration !! Would be a big problem for me on such a small boat. I know have lots of videos to catch up on. Wishing you âFair Winds and Following Seasâ.â€ïžđđđđ
,
Could you tell me the make of your stove (not the gimbled cooker). Enjoyed your video thanks for sharing :)
Is this the boat that used to be âarctic ternâ, and before that the boat that the late dixie dansercoeur took to antarctica in the wake of the belgica? If so thatâs quite some refit you did sirđź always liked this boat!
Why yes it is! Good catch! And thank you!! Cheers!
How much did the electric motor system cost?
Regen is vastly oversold by some manufacturers - bordering to being illegal in my opinion.
50kw engine el is easy to use as engine and power regen same time.
Not as a small altimator like bad balmar ore same class. But real diesel el engine up to 100eds of kw.
But 20 50kw easy in 50hp diesel
You got the videi all wrong, one should be facing the boat and the items which you are describing and not yourselfđ result: bad video start over đâșïž eager to see more boat!
gotta keep that radiation away lol
This is why 18:08 you shud have old diesel engine whit big 20 to 50kw el engine over gearbox.
Hybrid as diesel can be used in emergensy, BUT MOST OF ALL POWER UP FOR AN HOUR ORE 2 AND GO FROM EMTHY BATTERYS TO FULLY LOADED IN 2H TIME.
WHY NOT HAVE THIS ????
HYBRID MAN.
REGEN ON UR 15KW ENGINE HAVE BEAN UPDATED WHIT NEW FETURE !!!
