Thanks for a good summary. Electric drive is definitely the way to go, and it seems you've chosen a very sensible hybrid system, battery and solar size, etc. 43 KiloWatt-hour battery bank. KiloWatt-hours are a measure of energy. KiloWatts are a measure of power. Energy is power integrated over time. They are not the same. BTW, that is about half the capacity of an electric car battery. Two hours of electric motoring is way more than enough to motor out of a marina, off a mooring/anchorage, etc. And all of the energy used to motor can be replaced by hydrogeneration if there is enough wind to sail.

You're going to need massive advancements in batteries for that. The best batteries hold about 300Wh per kg, diesel is about 10000 Wh per kg. So if you had 200kg of diesel onboard (~200 litres) the energy equivalent in today's batteries would be 6666 kg of batteries, however diesel only about 30% efficient, about 2222kg of batteries . Future batteries people talk about 500 Wh, theoretical maximum limits (calculated max energy the molecules can store) with most battery technologies is limited to about 500-2500Wh per kg. So stored range will likely never match a diesel for a boat of the same weight.

Sirs, it's wonderful that you're posting these videos and underlining the topic of electrification for boats. I'm an owner/skipper of a Lagoon 52, wishing for an electrified future. I love that your approach to this is starting from scratch and designing the whole thing around propulsion and energy storage. A couple of issues though. To me, having both motors coupled to a single mechanical clutch kind of takes away from the redundancy argument. One could see that clutch as a single possible failure point and would want to see how long those could last with regular operation. Another point is that the 10 KW e-motors for this size boat are very small for marina use or for putting up sails in windy conditions. Yes, there's the instant torque, but I don't see it being able to take the major role for those operations, so why should I invest in extra complexity?
@HHCatamarans Жыл бұрын
Thanks for watching and writing. We think these motors are properly sized for the weight and efficiency of this new boat, but agree that it would not be sufficient on a Lagoon (especially a 52). Regarding redundancy, without a mechanical clutch how would we attach two different motors to the same shaft? Appreciate the comment!

FYI - This is a diesel boat with a little bit of assistance from solar. The 4000 watts of solar panels pointing straight up will not generate anywhere near 22kwh per day. ALL land based panels are angled at the sun for a reason. That along with dirt, dried salt spray, water droplets etc. and even less with the shade from the sails, it will rarely exceed 50% and average about 30% of the supplier's "rating". Also, I suspect the owners of a $1m boat will want to use a/c, especially in the brightest of sunlight in tropical areas where solar will thrive but the cool won't. The a/c alone will use more power than these panels will supply. The a/c, along with refrigeration, desalination, bilging, electric cooking, cloths washing etc. will require shore power or diesel power just sitting there never mind moving. Most non-high end cruisers will forgo a/c due to the amount of power consumed. Even large battery banks will not be sufficient. Wealthy cruisers will not likely be quite so frugal. I was kind of shocked when the Wynn's had family guests on board in one episode and still refused to turn on the a/c because of the diesel it would use, even after complaints of the close quarters and high humidity. As a non-boater that hates being overheated and as a tall lanky person that also doesn't like confined spaces too much, I don't think I would be returning to that boat, even with Nikki there.... ok, maybe I would!

Shaft drives have several advantages. For starters, they are more robust than sail drives, but the main reason is that by adding drag from the propeller to Hydro Regenerate power would be too much for a sail drive to handle. The other advantage is this allows us to move the engines forward and keep the weight off the transoms, which is better for performance and weight distribution.

I was a little hesitant getting behind their decision, since it didn't seem to answer all of my questions, but this certainly does. If I was in a position to be buying one of these, I would want some changes made (I don't like the cockpit layout) but I wonder if it would be possible to double the size of the battery bank. A Tesla Y sport model has an 80kWh battery, and they exhaust it in 325 miles or so. With the price of fuel, at least here in the U.S., hitting record highs, I'm sure that diesel fuel elsewhere must also be climbing, so the less I need to run the engines to recharge the batteries will an anchor, the better. But, I don't know if it's worth the extra cost of 40 additional kilowatts of battery capability. Still, thank you for this great presentation of the EcoDrive.

Or, alternatively, one hybrid engine and one electric only? Also, wouldn't a dedicated generator be more efficient at generating power than a regular Yammer diesel coupled with an electric engine in generator mode - even when running at diesel's most optimal RPM? EDIT: OK, you did explain later into the video the serial hybrid reliability concerns, which is understandable - at least until the electric propulsion gets deemed as reliable as a diesel and thus concerns no longer valid. Which I suppose is the case in EV cars realm already. Other questions still stand, though.

Everything you two have said is spot on... But let's face it... sailing is a pain. Instead of putting money into lines, sails, a mast and rigging, then take exactly what you have and extend the area for solar and put some more batteries on board. Embrace the parallel hybrid drive for propulsion. All of that extra solar helping out will increase the milage on the diesels to something tolerable. Not only will this new boat be less of a pain to use to get from point A to point B, but maintenance will be less. A person could be having fun and taking it easy instead of constantly trimming sails, switching sails, replacing chafed lines, greasing winches, fixing blocks and pulleys and all of the other pains that come with sailing. Build it and they will come. This is the boat that most sailors don't know that they need yet.

You're already putting the diesels in, already putting the batteries in, already installing the solar, and have already put in the work to make a great hybrid drive system.... but how much time and money would be saved by skipping the mast, winches, lines, rigging and sails??? The best part, is no part. I think that HH could make an awesome purpose built solar hybrid. There's no need for wrestling sails so you could shrink the trampoline and expand the cabin so that there's more living space and more roof area for solar. You can probably fit 10kw on a 44ft. Maybe another 3kw or 4kw could be flexible solar panel "wings" that stow under the main solar panels and pull out to clip onto the life line stanchions. 14kw on a 44ft boat would be enough to maintain a decent speed all day on a sunny day.

If you're referring to a serial hybrid the best way to do that would be with a standard marine diesel connected to a standard electric drive motor used only as a generator to charge a battery bank and another standard electric drive motor to turn each prop. No conventional gensets.

In the end, the primary source of propulsion is not a true primary electric motor and the diesel engine will serve as a genset, but it is not a true dedicated efficient genset.The result is an in-betwen solution including diesel engines still, which by the way can not be bluewater friendly. Hopefully some people like the Starlink guy believe in reliability of electric motors...

The beauty of this design is that you are not really adding all that much equipment. Instead of high output alternators on the diesels, we are installing the electric drive motors (these are practically one in the same). And by doing so, you remove the need for a Generator, so this reduces equipment. All boats are using LiPo batteries these days, so no additional equipment there. And by removing the sail drive to use a shaft drive, we are again reducing maintenance and the potential for corrosion. It's a great concept when you really compare it to the traditional systems being used today.

It's is about 888 watts per hp. Length of water line with 11 hp it isn't doing much over 5 knots. Perhaps add super capacitor bank because lithium batteries do heat up and loose power. Super capacitors can run electric motor direct from solar. And skip the power loss by slow charging lithium batteries. Those lithium batteries only cycle so many times. Super capacitor bank cycles millions of times. The super capacitors will cycle so batteries don't and batteries will have less hard cycles.

A boat designed from the ground up to be a hybrid will NEVER work to be fully electric so PLEASE don’t stop there like Toyota did with hybrids. A fully electric boat designed from the ground up would get rid of the huge heavy fuel tanks and replace them with at least 160 kWh of batteries and would have solar on every surface, including the top and sides of the amas and the coach roof would be redesigned to extended ALL the way aft over the davits to maximize every surface for solar. No one really wants a hybrid boat because that means you still have the hassle of diesel fuel and you still have to maintain gas engines. Fully electric has no hoses, no clamps, no filters, no oil, no belts, no gears, no fumes, no noise, no water pump, no fuel stops, no Jerry cans, no fires, and lower insurance. LESS MAINTENANCE means MORE SAILING! Please stop designing your boats to be hybrids like Toyota and start designing them to be electric like Tesla. Before Tesla, everyone said fully electric cars wouldn’t work or wouldn’t be fast enough or go far enough. All of that is not true with cars and it isn’t true with boats either. Sorry to be harsh. I know you guys are trying, but you’re focused on the wrong thing. Stop believing fully electric boats won’t work. You just have to build them as fully electric from the ground up.

Firstly, thanks for sharing.... Couple of points here.... firstly Hybrid configuration is old before it ever arrived (like with cars). The point about no one doing this before is INCORRECT. There are compromises everywhere and ultimately you have 4 engines.. 2x 10KW/15HP electric engines are pretty much useless... you want to use these when coming out or into mooring or a marina... there is just not enough power in those to be useful esp if there is tide/wind. The point about driving the boat at 7.5 knots for hours on electric misses the point of the performance cat... can we see what she will do in light conditions (you didn't even mention this) ? Good luck to anyone trying to trouble shoot that motor in the middle of the Pacific. Lastly you've just added extra weight on the battery and the back of the boat... really need to question the decision making here... to me the best solution is a) great sailing boat (btw: those daggerboards will create a lot of windage) and b) the way people seem to be going is 2 x 20kw+ electric engines and one diesel generator (hopefully removing that generator as technology evolves and a lighter one than the monstrosity you just mentioned).. Lastly, your point about redundancy made me realise that people advising you have not really sailed offshore... there are so many parts that things constantly go wrong with diesel engines... its constant maintenance...Almost zero on electric motors and you can wire in redundancy. Overall to me this boat is ok looking (except that back which is a mess - love to see the hydro analysis on a seaway on that) but fanciful and feels like its been designed by a few naval architects straight out of uni with more focus on looks and marketing than sailing.
