[@rolandtb3]

You covered weight distribution, weather, cruising range and lifestyle, prop type and size, hybrid option(s), spcl. speed/power/torque/rpm, regen, augmenting battery size and location. Any projected broad cost comparison options for this boat size? E.g.: 2 full electric engines, 2 diesel engines, 1 new diesel hybrid & 1 new electric engine, 1 used hybrid & 1 used electric engine, 2 diesel/electric hybrid engines. Cost to be separate or include props/fuel tanks/battery bank and auxiliary equipment. Down the road discussions about noise, heat, fuel, comfort, reliability, maintenance, ease of maintenance, parts availability, redundancy, maintenance work area space.

[@LoanwordEggcorn]

A better way to do a serial hybrid is to use a conventional marine diesel like a Yanmar connected directly and exclusively to the same type of electric motor and controller being used for drive motors, but used purely as a generator to charge the battery bank. Marine diesels are much easier to maintain than gensets and vastly more space, cost and weight efficient. That also makes spare parts and maintenance simpler since all of the electric motors and controller are the same throughout the boat, used for both propulsion and Diesel-powered electricity generation. To recap: use a marine diesel directly coupled to an electric motor used purely as a generator to charge the battery bank instead of a conventional genset. So no conventional genset at all. Use a Yanmar plus another electric drive motor and controller purely as a generator. (This electric motor is run in regen mode only, to charge the battery.) Some production hybrids are already doing this and it's a much better solution than a genset for multiple reasons. That all said, a parallel hybrid is probably a better solution than serial since it's more efficient to be able to drive the prop directly from the Diesel, AND it has 4 way redundancy, being able to move the boat using 4 different motors, 2 electric and 2 diesel, independently (if clutched between each Diesel and electric). Due to the redundancy, it should be a more reliable system. As you correctly note, a serial hybrid introduces many single points of failure. That said, since the battery bank can be charged from a great diversity of sources: Diesel, solar, hydrogeneration (regen), shore power, windmill, etc., any electric drive can multiple redundant energy sources, even if it's in a serial hybrid. The solution you came up with: parallel hybrid in one hull plus pure electric drive plus a larger (combined house and propulsion) battery hank in the other hull is a good optimization. There are many different ways to organize hybrids.

[@lbb101]

Hey Matt, you explained the parallel hybrid system perfectly the last time. I think the many modes it brings with regen, gen, purely electric, purely diesel, and diesel+electric working together might have been "complex" for some. I think it's a smart choice.

[@chet3louisiana558]

Good thinking. For every ounce of weight you save in equipment you can swap for added booze. Good video.

[@dc1544]

Also make sure when you do your battery banks you do not daisy chain them but run each battery to a busbar(charger and inverter) connect to same busbars. This will lower the load on each battery in high load usage. Example if you have 4 5k 100ah batteries in daisy chain and pull 200 amps that will pull 2C through each battery and over work them while loosing to heat loss. Busbar with the same 200 amp load pulls, .5C from each battery which translates to less heat and more charge cycles so longer life of each battery. I have spent hundreds and hundreds of hours researching(testing) this as I have 4 15k batteries in my house setup with 2 5k inverters which doing busbars will pull at max .5C and normal use .15C from each battery. The only thing to make sure of is each positive cable must be same length and can be smaller size since you wont go over 50 amps per battery, same with negative cables they do not need to be same length as positive side just all negative cable same length. Hope this helps. if you need you can contact me.

[@claudeelliott3993]

Well explained, Matt. Way above my paygrade but so are a lot of other things!! Looking forward to this hybrid system showing up and getting installed.

[@mikeallensonntag]

When you end up looking at the solar setup make sure you carefully plan the way panels are wired and how many go to each charge controller. I'm not a expert in this subject matter but I do know when some panels are shaded for example by your sail it can really effect the rest of the solar arrays performance. These sets of arrays you have is really going to take some careful planning to gain the most power possible.

[@mikeallensonntag]

Just without really having sailing experience and well I'm not solar expert by any means I would split the solar arrays into four sets fwd port, fwd starboard. Aft port and aft starboard. That way no matter sun direction or sail no sail hopefully you have atheist 2-3 array sets generating good power without shaded panels.

[@freedomrider30]

Wow, Max Cruise becoming a house hold name! Awesome!!! 👍👍😎😎😎

[@marioluque1107]

Smart move going forward. Technology has advanced to the point that fuel dependency alone is not sustainable!

[@bunyipdan]

Fantastic opportunity (well done Max Cruise!) ..... glad to see someone apply the single diesel hybrid dual electric drive, has so much potential for multihull sailing. There are a couple of advantages, applications you missed in your explaination. One of the biggest is the trade off with loosing one diesel, so many people place a huge weight on having two diesels = ultimate redundancy but I believe this is totally dominated by the weight saving, the reduction in cost both initial engine purchase and ongoing maintenance and the overwhelming pros and modularity with parallel hybrid. Then there are the "cheater" sailing benifits .....like being able to easily have the ability to force maneuver, at the flick of a switch use the electric motors to help tack the boat while under sail in light wind. To take advantage of heavy weather sailing by setting electric drive produce regen down waves and power up waves thus reducing the annoying buffeting multihulls can get due to changes in apparent wind angle and speed ..... better managing more difficult sea states (see youtube interview with Waypoint hybrid diesel 410 Lagoon). Hope you end up going 48VDC wiring or at least 24VDC to reduce cost and weight. Almost unnoticed in the background (@23:56) an Osprey diving for fish, then shaking off water with a characteristic in flight shimmy as it flew away By the way (@21:20) not sure you are at a "Net Zero" energy budget if you are running your engine.

[@armslength2618]

That's why you use two-stage generators and eliminate propu-batteries and the weight and cost penalties of those.

[@bunyipdan]

@@armslength2618 not exactly sure what your comment is saying.......i think for this project the idea is to utilise sail, solar and regen and limit the burning of fossil fuel.......if you are suggesting serial hybrid system then running a generator to power vessel house load and propulsion might make sense in a large non sailing vessel application but cannot see any advantage in this situation. The parallel diesel should be more of the fall back redundancy not the primary but the advantage is diversity of options (being able to run in isolation or in concert), maximising effeciency, and providing redundancy in power and propulsion ...... which is hard to beat.

[@thomask5295]

Happy for you guys! Congrats on going Electric / Hybrid.

[@IainMcClatchie]

One thing I have not seen mentioned about these hybrid systems is that they should make it possible to go more miles per day, even without using the diesel. The reason is that the hull drag power rises faster than linearly with speed, and the available wind varies. So if you've got wind that would blow you at 10 knots for an hour, you might turn on regen and slow to 9.5 knots for that hour. Later, when the wind has dropped and you're making 4 knots, you can turn on the electric motor and go 5 knots for an hour. In the same two hours, you've gone an extra half mile. A half mile isn't much but you do this for more of the day and it adds up. The important point is that you speed up from going slow more than you slow down from going fast.

[@gavinferguson]

good job makes sense your probably the best advert for maxcruise and fast cat tech

[@karlfair]

Lady Jessica, you have the wave down pat. Congratulations on the hybrid system. It will be interesting to see the install and how it performs.

[@garycasey5788]

But remember there is no such thing as a free lunch. The regen will slow the boat and/or require the sails to be "powered up" in order to generate the power. Using one engine to drive both props probably increases the propulsion efficiency because of doubling the total prop area, but the hoped-for reduction in BSFC is probably not as much as might be hoped for. Still a good system, but not magic.

[@JCrook1028]

Regen doesn't slow the boat very much at all.

[@rainfinger]

We are an electric Bristol 35, suggesting you put extension hoses on the two grease nipples, lubricating the fore and aft bearings, making routine maintenance much easier.

[@desertdweller4951]

Sounds very appealing in so many ways. Thoughts and Prayer, you two have found a benefactor in Max Cruise and there new approach in sailing.

[@dc1544]

YES YES. Your new hybrid will come with lithium ready alternators. That is huge as if you add them to a diesel engine it costs around $3,000-$4000 each which saves you money since they are sold with them. Solar and using the hybrid to regen - charge when sailing is also huge. You have a cloudy windy day and batteries are low just go sail for a couple hours. Seas are to big outside the anchorage run engines for 30 minutes. If you get a solar rack on the back order Bifacial solar panels so the sun bouncing off the water will reflect up under the panels and give you more watts of solar. I am so excited for you both. Is it done yet lmao.

[@stephenmurray9850]

So , if I understand right , you should be able to get another 25% ( conservative estimate ) extra range from the 1 diesel motor + 2 electric/regen engines if you are unable to sail for some reason on the amount of fuel you have onboard. I guess if you have good sunny days you would get even more range. I think this is a brilliant system you have chosen for your cat. get news guys. Oh and the add for the "Lady" was VERY funny . Well done for that too, must have been fun to do that for your sponsors.

[@Tomm9y]

Interesting solutions, hope you can sell the spare engine for a good price. I guess wind strength and angle will be a big factor in speed and power consumption. I think Terry deserves a credit for his work developing and testing the systems.

[@bkackman]

Loved the opening "lady" segment, especially Jessica standing and waving in the wagon. Such a proper Lady! I also get a kick out of Jessica's neutral face as Matt goes full geek on the technical discussion...which was interesting by the way. I love the team arrangement that Max Cruise has developed with you. Fantastic news to take your existing investment and working toward the system you really wanted. And I'm such a geek relative to regen capabilities (in cars, boats, etc.) so I'm (almost as) excited about this development. Now you have to complete the build faster because now I know what the presents under the Christmas tree are. I can't wait!

[@ED3]

[@wernerlindtner2742]

I think it is the best concept. Diesel consumption and engine hours will be very low. A 2nd Diesel engine would cause double service affort, less efficiency and more weight.

[@melee401]

I find myself liking this system. I take it the batteries will be placed on the totally electric side hull to balance out the weight load. This to me is the only reasonable "electric" alternative I have seen for a cat so far.

[@CapriceV6]

Not to mention, like he said, put the batteries on the owners side. The noise level will drop dramatically. Givin the owners at least a decent night's sleep if under motor.

[@SamuelKTennis]

OK, I get it. But tell me, really, do you like it? ;-) You sound really excited. CongoRats!

[@PauliJuppi]

That watts to speed graf looks very similar to what I've found out on my electric sailboat. Every gained knot in speed doubles the watts needed and then a bit more when you get closer to max hull speed.

[@armslength2618]

The biggest gaffe is planning or expecting to use batteries for propulsion. The second is failing to use the potential to eliminate a through-hull rotating direct driveshaft. Firstly, propu-batts are not needed in an electric drive system - you can much more efficiently keep your energy stored as diesel or jet-A. No need to first combust it, dump converted energy down into a propu-batt with serious loss, then bring it back up with another loss hit, before sending it to your motors. Regardless whether the gen-head and motor are separate or the same unit. Just do it directly. That covers energy storage. Propu-batts are not needed for electricity conversion and control either, as you can use a conversion bus manifested with modern power electronics, like in the Honda EU-series generators that have been around for a while. You have 3-phase generated power sent into a DC conversion bus then instantly reinverted to whatever voltage and frequency your heart desires using power electronics. A small fast battery on the DC bus could be added for fine-tuning power quality. Current feedback control, measured on that DC bus, adjusts the generator engine speed. Remember, the biggest diesel-electric machines like railroad locomotives and cruise ships don't use batteries stuck in the middle of their engine systems - there's no point. Propu-batts together with all their associated conversion sub-systems are also an additional, unnecessary point of failure and a huge expense. A two-level (one small, one large) genset strategy is better by far. One small engine efficiently running to power propellor motors when slow base loads exist such as in harbor maneuvering or optimizing on fuel in the doldrums, with the second large engine kicking in and adding to the first in strong headwinds or channel currents. The total power of each can be split over both props and hulls as needed electronically , and they could be placed fore/aft with cabling as needed to optimal weight distribution. Either genset is a backup to the other too, on top of the sails that are supposed to be your main propulsion anyway. Finally, use of submerged extractable propulsion-pods in each hull can completely eliminate prop drag when sailing, and be raised to easily un-foul propellors. Each pod consists of a streamlined motor casing with prop attached, just like current ABB azipod motors but downsized. No through-hulls or cutlass bearings or stuffing-boxes. Lower the pods down through slots in your sugar-scoops like a powerboat stern-drive would. Electric cables connect to the pods, which are slaved to each other and rudders for directional control. Pull the pods for maintenance or engine-off sailing and the rudders stay aligned with each other.

[@AORD72]

What? They are performance cat, you will hardly motor, they only need motor short distances. In the event of an emergency the best thing is to have a direct drive diesel, way more efficient with long range. The big every day factor is the comfort of the electric motors.

[@bunyipdan]

Your priorities are obviously quite different, and appear to be willing to compromise in very different areas. IMHO A reasonably sized lithium battery bank matched to solar and hydro regen is much more preferable to running a genset. You dont have to go over board especially if you have the advantage of a parallel hybrid system that alows for longer distance travel using direct diesel drive and other power generation option Not sure a Honda EU is going to support propulsion demands let alone a modern cruising cat of this size.....so if you dont want a large battery bank then you want to be running a genset a lot? Why? Because batteries are too expensive, less efficient and complicated? So extractable/retractable propulsion systems are a compromise as well, can work ok for coastal cruising serial hybrid .....if its an option like how the smaller light weight Seawinds or Schionning designs run outboard pods or even some cats that have custom extended surface drives both of these tend to be more exposed than tradtional drives when deployed and are less effecient and have reduced effectivness in heavy sea conditions. Unfortunately none of the compromises the systems you have described appeal to me....so we will just have to agree to disagree....

[@armslength2618]

@@AORD72 The amount of motoring distance depends upon intended usage and the situations they find themselves in, not what kind of 'performance cat' it is. And direct shaft drive still doesn't get rid of the drive shaft through-hulls and all their liabilities.

Thru hull failure can't sink our boat, so are of little concern.

[@AORD72]

@@armslength2618 "doesn't get rid of the drive shaft through-hulls" like almost every other cat out there. All well built cats have water tight compartments so it is not a problem. Sure "motoring distance depends upon intended usage", but lots of people like to sail. Sailing is smoother and quieter, so you hardly motor. I see the engines as a backup to the sails. With a performance cat the key is to be able to sail in light breezes so you don't have to motor.

[@gilcore5245]

WOW, just wow

[@bigalon3wheels]

Do you plan on having a fossil fuel back up power source? A 100 % anything is not always the best way, but can eliminate the bad diesel found at the islands fueling locations by full Solar. Adequate battery storage capacity makes for a more efficient power source and wind is in fact your main power source anyway any other propulsion is simply a back up. When built to be solar does make a world of difference performance wise at sea. I am sure you guys did your homework there. Looking forward to seeing the end result on the water.

While you didn't explicitly say it, the other benefit is on the comfort side, by having the electric motor in the owners hull you do away with the drone of the diesel motor. The electric motor should be virtually silent, which ups the comfort level. It is a really interesting technology, and has real promise.

This is the appropriate solution until we have access to a power source that is free of fossils AND can be stored in as large amounts and as safe and as reliable as the well proven diesel. IMHO. The best is not to go motorsailing/driving/flying of course Aren't we all using energy on an expensive loan to earth? Even the production of batteries and pv panels is at a cost. But for now we do what we can and invest in the next "best" thing and stimulate kapitalism to go further in renewable energy propulsion systems. It may take who knows how long for a true one. We need hybrid now as the next step. Very good choises you made. Thx for the advocacy to all of us. It is stimulating.

[@danelsener9558]

Looking forward to seeing your hybrid setup! Is your one diesel engine still going to have a high output alternator or is the electric motor attached to that diesel the only way to generate electricity from the diesel engine?

[@MJSailing]

The Yanmar engines come standard with a 120a alternator, but it is internal regulated - so derates quickly - and will be used to charge the 12v start and emergency house bank only. I'm concerned with loading the engine much more, so probably won't add a second alternator to this engine.

[@TheOldGuy]

Good information and hope more of the details will come in future videos. Just a few questions. Is your house bank going to be 48VDC, with a DC-DC for your 12VDC equipment? What brand / size is the standalone motor and does it also have regen capabilities? Finally do you have a rough cost for the conversion? Thanks really enjoying this series! Keep at it!

Aren't modern AC to DC high frequency converters very efficient that you would just setup like a normal house and run everything from AC?

[@milt7348]

Congratulations.

how would you get the same HP output if you have 2 different motors in each hull?

[@IM-YOUR-MR-NOBODY]

some are using industrial alternators for extra regen why not put 2x on the side without the diesel engine ? but if you had 2 each side would you even need the yanmar motor ?

Look at that “pageant wave” in the thumbnail 😂. Great news ✌️😊

[@jeffgriglack9624]

So, how much for the other diesel?

[@davidwarnes5158]

With your experience doing the same route around Scotland, further north, how will your system perform, the usual sunny carribean lots of solar , youl have a large battery bank , run all electric , 3 burners , but that has to be put back in, ?

Hi-bread set ups are great for making toast. :-)

😂👍

How much diesel will you carry and how much distance will you be able to go i case of electric system failure? Just curious.

[@MJSailing]

We have two 50 gallon tanks (but I think we'll only use one). This would give us a range of about 700 miles on diesel alone.

Great choice, now back to sweeping sand lads!

[@rickfucci4512]

Great.. I'm excited for you...

[@dereksellars]

Oh YEAH!!! This is really interesting. Thanks :)

[@Lordlindef]

and if not diesel so small as 40hp = then can have 2 x 50kw el engine

[@lyfandeth]

If you can motor under diesel alone, does that mean your diesel engines are directly connected to the prop shafts? Or clutches?

[@exposs8579]

Good luck. About to "learn a lesson" with those lithium batteries.

[@sawahtdeekrahp5305]

That hybrid setup is so cool! I would assume all or most of the batteries will be placed on the electric motor (only) side to balance out the weight of diesel/motor side? I would keep the 2nd Yanmar as a spare since you got such a good price on it.
