How Our Hybrid Electric Motor Works (+ solar & hydro)

[@gonewiththewynns]

So many Curious viewers! The most common question seems to be "Great system, but can you get it serviced anywhere in the world?" and the answer is definitely yes! The diesel engine is a fairly simple marinized Kubota engine, so parts should be readily available and any diesel mechanic worth their salt should be able to fix anything Jason can't. The electric motor is also super simple, and HH techs will be able to remotely log in to the system from anywhere in the world for troubleshooting and diagnostics. Hope that satisfies your "curiosity"! Curious Minion

[@russellduke4469]

Thanks for your channel. A question, everything being digital, are you worried about lightening strikes or any electrical failures?

[@dansbrown1313]

Hello Jason and Nikki, with so many options available, I'm wondering if the Yanmar engine is available?

[@yewtuber]

The amps are what kills you, not the volts. That was very dangerous comment coming from the factory rep.

[@Metal0sopher]

Also look into a 4 blade prop vs. a 3 blade. 4blade require more torque, but that's what electric motors do thus 4blade props are more efficient and more responsive than three.

[@LoanwordEggcorn]

@@yewtuber Touching a million amps at 1 volt probably won't kill you because it's not enough voltage to break down skin and make it conduct. It takes more than say 50 volts to make skin conduct, which is why low voltage systems are under 50 volts. Also it turns out that water, even seawater are NOT very conductive, so the risk of electrocution from water + electricity is not a great as people think.

[@plfreeman111]

As an engineer with a career in automation, I'm impressed, and also recognize that you two will really need to learn these systems. I'm confident you can learn to troubleshoot and repair, but it sounds like it's going to be a whole new class of debug from what you had before.

[@AndrewBlacker-wr2ve]

But Wynns have a very intimate understanding of the entire system. I've been critical of Jason's lack of mechanical knowledge. That being said, he has self educated about not just mechanics but also system design.

[@gonewiththewynns]

The diesel is very uncomplicated, and the electric motor itself is also very simple. Techs will be able to access the system via WiFi, so the techs at HH will be able to help troubleshoot from anywhere in the world. Curious Minion

[@stevewildman1045]

Jason has had a Supreme learning curve from his day of Rving. I had doubts for this duo as they started there lessons on basic boating and sailing. To the Wynns, " You have done well Pilgram" Much respect... and YES you are building the vessel of my dreams of 25 years ago.

[@alliejr]

The electronics and controllers will be the problem area. You're right, the diesel and electric motors are simple. But the electronic and software "glue" can make it all go wrong-- and unless you have access to the code to debug, it will be a challenge.

[@rileybri]

I think that is the beauty of this system it is very simple mechanically and can be run fully analog if needed.

[@jackwickman2403]

When the drive belt from the prop shaft to the motor/generator fails you will have to disconnect the prop shaft flex coupling and push the shaft aft to replace the drive belt. While this is not that difficult it could be easier. You could put a spare belt or two around the prop shaft during install and zip tie them into a safe position clear of any moving parts. Then when the belt fails just slide a new one forward and onto the pulleys. You will only need to slacken the belt tensioner and then retighten it with no need to disconnect the prop shaft. This could be a plus if the belt fails at sea under difficult conditions. Thanks for showing us your beautiful new boat. Happy sailing.

[@LoanwordEggcorn]

Yes, but belts also tend to be highly reliable. More reliable than shafts, gears, universal joints, etc.

[@fredbugden3511]

That is a very good idea.

[@stephenfraser2521]

Excellent Ideas

@jackwickman2403 Good eye and nice catch. And yes, HH delivers the boat with a spare zip tied exactly as you described. You get the gold star this week! Curious Minion

[@LoanwordEggcorn]

@@armslength2618 Belts are highly reliable in power levels and applications such as this one. We agree they're not suitable for use everywhere. (Lots of engines use timing belts, for info. Some motorcycles use belts as a final drive between the gearbox and rear wheel. Google: "What motorcycles have belts?")

[@colourful64able]

There's no way to get stuck in the middle of the ocean

[@stephensidaras7416]

Hey - Get them to put two extra belts on each motor and zip tie them out of the way now as they are probably very difficult to replace the belts later. That way you just cut off old belt and slip new belt in place. I bet it is very hard to get a new belt around the prop shaft once mounted in engine room.

[@TheSailingFamily]

Yes, that is what HH does. Ready to go!

[@robc1952]

wow, looks like a great system, 1 thing not mentioned is that most trains since 1913 are all diesel-electric, As early as 1913, an experimental 60-horsepower diesel-electric railcar appeared in Sweden. About 30 cars of this type, but with more powerful, 150-horsepower engines, soon went into service in Sweden, Denmark, France, and Tunisia.

[@cliffdavis5244]

What an amazing boat, the HH 44… Can’t wait to see you sailing her in your future videos!

[@echobravo1105]

I really like the fact that alongside the considerable amount of tech on this boat, at the centre of it is a fairly agricultural diesel that I could fix with a bag of spanners. And as a bonus its shaft-drive too. I've never really been a huge fan of common-rail or saildrives. Getting more interested in HH the more I see of them.

[@HopeOfJoe]

This architect just gave the best description of how this system works. B. R. A. V. O. ‼️

[@MrDonJBerg]

Same system as used on WWII submarines as there were called Diesel/Electrical Boats. A German sub was captured (U505), as it's batteries were "Flat", had no power thus have to surface and surrender. Did the same trick, as it was being towed by the Americans after capture, the props were spinning charging the battery's bring it back to life. It is now in a museum in Chicago..

[@LoanwordEggcorn]

That means it's not the same system. This system is a parallel hybrid where either or both the diesel or electric can move the boat independently. In that way it has 2 way failover redundancy. Any one system can fail and the boat can still move. If the sub could not move due to discharged batteries, then the sub was a serial hybrid where the combustion engine acted as a generator to charge the battery and the Diesel could not turn the prop directly. It's also possible the diesel had a problem or ran out of fuel and could not start.

[@MrDonJBerg]

@@LoanwordEggcorn It was kept down due to depth charges, batteries ran out, that was it. U505 was surrounded and had no were to go. The engines were started with compressed air. The WWII subs engines were NOT connected to the prop shaft, but to a generator which charged the batteries, OR powered the shaft motors directly. OR full motors or Full battery charge. The entire sub was controlled by "Maneuvering" a small room maned by 2-3 people that controlled the flow of current...Quite the setup. To me the similarity's were striking.

[@LoanwordEggcorn]

@@MrDonJBerg Thanks. If the Diesel can turn the shaft directly, then it's a parallel hybrid.

[@MrDonJBerg]

@@LoanwordEggcorn The Diesel does NOT turn the shaft directly but turns a generator which powers a motor which turns the shaft...

[@ChrisJones-yh2os]

Wow, I think you really lucked out with the engineering talent at Hh. In a way, I think very talented engineers are attracted to challenging forward thinking projects, and that has happened here. At a legacy boat manufacturer, I suspect your talented engineer would be stifled by older engineers who just want to do it the “way they know works”. I am really excited to see all this tech come together.

[@powerflowmarine]

It's truly an incredible advancement for the marine industry, one that we are STOKED to be a part of! Electric sailboats are the future!

[@thomaswillemin9181]

I’ve been doing Building Automation for over 27 years and my concern is leading edge tech vs “bleeding edge” tech. There are many interconnected systems that concern me with how well they will hold up in a marine environment. But this is amazing stuff when it is working right. I sincerely hope it gives you decades of worry free service!

[@georgeburn961]

At least it's a simple bolt-on generator/motor that presumably can be isolated mechanically if it fails. And a simple gearbox for the engine using existing tech. I've seen variable pitch props driven electrically to optimise regen efficiency, which seems great but again prone to failure, potentially. And this parallel system wins hands down for redundancy IMO.

[@TheSailingFamily]

It's been in production for over 15 years, so it's not leading tech or bleeding tech really...

[@user-od9iz9cv1w]

What impressed me is that they are repurposing a well established system used for years on river boats. Just looking at it, it looks simple. What is more ubiquitous than a Kubota diesel or a belt drive motor generator? They have some new software to perfect, but that can be updated wirelessly.

[@peterdrury5627]

Hello, Nikki and Jason! Your timing in the adoption of this particular hybrid system is perfect. The system is cutting edge, but mature. James and his team have brought an amazing level of sophistication and refinement to the final product, always with attention to its ease of use by Sailors. Stepping away from things technical, the bottom line will be a whole new level in your quality of life on the water.. Well done!

[@justlookin3]

[@51marshmellow]

This was fascinating and relatively easy to understand the basics, all due to the three of you, from explanations through editing ! Thank you.

[@theonlywoody2shoes]

Somebody far wiser than me once said that “simplicity of operation is a result of far greater effort at the design stage” . I think the HH hybrid system is a perfect example of this approach. Great video as always 👍

[@w8stral]

I would say that is 100% true. I just wonder if the B&G interface craps the bed(they do), does everything still work or have a backup? Electronics are great until they do not work and modern electronics there is no "fixing" them, it is just 100% replacement.

[@codegame027]

It is worth pointing out that these hybrid units are not proprietary to HH but could theoretically be retrofitted to existing boats.

[@w4vp9kf]

I had the same engine/transmission. Raises three questions. 1) Never would start without using glowplugs, even with outside temperature at 90F. That takes 50A for about 10s for each engine PLUS the starter motor load when turned over. 2) Could not stop without pulling manual decompression handle. Has this been replaced by using a solenoid? If so, is there still a manual decompress if solenoid fails? 3) Running transmission in 'N' wasn't recommended, had to be in 'R'. Ask questions about this!

[@Brian-os9qj]

Simply fascinating, but complicated! It is just a matter of the experience bringing familiarity. The Wynns will do that. Fair winds are on the way. Enjoy.

[@kathyline11]

That young man is one intelligent person!

[@nathanbannister8502]

We were just at Ft. McCalister GA where the current runs at 4 or 5 knots easy. You could anchor in the river there and generate in both directions with the tide coming in or out using the hydro regeneration mode and wouldn't really need anything else. The battery would keep you going through the slack tide. Very cool! Amazing there isn't hydroelectric on all of these tidal rivers for the towns along them. What a missed opportunity.

[@carsonc1272]

There are a lot of ways to accomplish a hybrid. I'm happy to see that HH has put the thought in to do this 100% right. I'm an electrician and kept looking for something to poke a hole in but this system is awesome. Great job HH! And Nikki and Jason also deserve credit here. You guys always put the required thought into what you're doing instead of just going with the crowd and doing things the same way it's been done for the last 100 years. Make sure to get that dishwasher so you don't make a liar out of me.😘

[@wildwestunlimited]

So!.... I was REALLY concerned about how much solar you have was really NEVER going to get you to a FULL state in your huge battery bank..... NOW I get it, with this system, you'll be sailing almost forever with VERY little to ZERO use of any fossil fuels whatsoever. This means, NO MORE carrying all those big HEAVY diesel cans when you go ashore, which ALSO means, NO need to even HAVE those big cans for your diesel storage. Man, what an IMPRESSIVE system! I'm SOOOOOO HAPPY for you and Nikki!!!!

[@ShaunBowm]

Seeing your journey over the last few years, its also cool seeing the synchronization of your life/dreams/technology melding at the right time

[@FrankDoucette-q9j]

Lots of comments from folks who have not designed, built and sailed an electric boat for years. I have. My Pearson 36 had a similar 10kw brushless electric motor and in my opinion, the HH44 setup is sized right, practical and functional. Far superior compared with my DIY system. In short, I have no doubt that it will work & Jason, you are going to love this propulsion system!!! You have 2 generators on board. You have 2 engines and 2 motors - each capable of moving the boat on their own. I know of no other boat with such redundancy. Just one question: how to change the belt? I know it lasts a long time (mine went over a year with heavy usage). Must be a coupler you can disconnect to pull the belt off the shaft.

[@gonewiththewynns]

Good eye. HH delivers the boat with a spare belt already inside the loop & zip-tied out of harms' way. That lets you wait for controlled conditions to install another spare for the next time. Curious Minion

[@ecleveland1]

I really like all of the redundancy in this setup. To be able to move the boat in no wind without using diesel fuel is a huge game changer in my opinion. Less wear on the diesel engines because you don’t have to run them for short trips is also huge .

[@bmitch3020]

When thinking about maintenance, my biggest concern is the control systems. There's still the prop, belts, transmission connections, but those will be relatively easy to diagnose and fix. While the electronics on the control system, the wiring, screens, etc are the things that will be hard to just diagnose, let alone repair, while at sea.

[@user-od9iz9cv1w]

Great video. To me, this is the perfect setup for a live aboard cruiser. You could literally just use the diesel very sparingly and use very little fuel. Quiet. Clean. But always there to get you away when required or to charge batteries for AC and other living comforts. And it is still a performance sailing machine. I love it.

[@GolaniBalagan]

One should always consider the worst case scenario which in the case of this system would be thermal runaway from the Lithium batteries. A fire like that would be impossible to extinguish at sea (on land too). Boeing solved the problem on the B787 by encasing their lithium batteries in a fire and heatproof steel casing after several serious incidents that grounded the aircraft. Are your batteries in a steel (or other material) protective casing?

[@honesty_-no9he]

Not if the batteries are LFP.

[@mattcherry276]

I live a couple of miles from Braidbar Boats who feature in the magazine article you showed and regularly walk the dog along the canal past their yard. It's an ambition of mine to live on a canal boat, they are one of the top canal boat builders in the UK and I'd love to have them build a boat for us so I've looked into their hybrid system, and what was described here sounded very familiar, because Braidbar also use HybridMarine! One big advantage on a canal boat is engine efficiency - you size your engine, gearbox and prop for going against the tide on a fast flowing river with a gale force headwind but then spend 99% of the time pootling along a current less canal on a calm day. Putting the engine to so little effort means it runs really inefficiently, so adding the generator and working the engine hard means it's massively more efficient and you're using far more of the energy in the diesel fuel, stuffing it into the batteries and then, once fully charged, switching off the engine and using that energy for propulsion for far longer than you had the engine on for. On canal boats in the UK you can get enough power from solar for domestic supplies (though not necessarily in the winter) but the sun isn't ever really bright enough and there isn't enough space for panels to generate enough for propulsion unfortunately. Braidbar also provide a remote controller so you don't even to be on board to move the boat, e.g. if you're single handed and going through a lock - David (Cruising the Cut) did a video about it a while back. Wow! Suddenly this video went from China to so close to home!!! Top stuff!

[@gradyluyt6998]

I love the emphasis on two separate systems and a normal run of the mill diesel that anyone anywhere can fix. I love complex done simple

[@brendanh8978]

There's something really cool about the idea of sailing into some pristine remote anchorage, using only electric to maneuver while dropping the hook, and then recharging the batteries with solar. No loud diesels running, no stinky exhaust or fuel smells to detract from the quiet and fresh air. Will be hard to run totally off solar without turning off a lot of the luxury systems and sweating a little, but would be doable. You can really be quite self sustaining for a long time. Food becomes your limiting factor,.

This is fantastic what HH has done here on your 44. I thought I watched an Antares Cat Hybrid that used a similar system a few years ago. They even pointed out the straight drive vs sail drive idea plus added it was safer if it hit a log. I went back to look at the Antares 44 Hybrid after looking at the HH 44. The takeaway is that Antares is clunky vs the clean lines of this new HH. I actually could not believe how my memory did not see all the improvements that HH has made to the cruising cat. In the review of the Yanmar/Electric drive on the Antares, the HH shown here is more versatile than the other one. This 44 cruising HH just may be the best of both worlds. Sorry if I am too wordy.

[@markspann]

First a disclaimer : I am NOT a sailor, nor have any general interest in the lifestyle, but have been watching your videos because, quite frankly, it is simply a foreign subject that you and the wife have made brilliantly fascinating. With that said, I am keenly interested in the concept (which must be proven and I'm sure you will as you have to) that you can power your lifestyle with a maximum of free and/or renewable energy sources, depending as little as possible on diesel engine electrical power propulsion. Now you will have my full attention with every upcoming video to see how this new tech, whether leading or bleeding, will shake out.

[@workdogwern4716]

For anybody keeping track, 1 horsepony is 750 watts. The electric motors are about 13.5hp (10kW) combined. You're not going to put it up on a plane with that kind of power, but it's plenty to move the boat around. When he's talking about recharge, he mentioned 250w (1/3hp). That's just energy conversion losses. It's a very cool system, and I think the Wynns will learn to make great use of it. I think the practical reality is that the electric motors will be great for mucking about at low speed. It's great when he mentioned about running diesel on one side, and electric on the other. I don't think much long range cruising will be done on the electrics however.

[@jamesmarinelli2177]

[@craybro]

Very interesting! Most of the recent boat hybrid systems I’ve learned about use a generator to power an electric motor with no direct diesel propulsion. I can see how this system works better for extended motoring but would go with the other system for shorter range motoring for near silent power underway and at anchor charging.

[@glasslinger]

One question I would ask is what happens if something breaks way away from a hhh service center. Can normal shops you find all over the world work on this thing? If something terrible breaks is it just ordering some parts and a local shop can do the work, or do you have to also take the boat 1000 miles to a qualified shop?

[@markryan7109]

I love seeing a belt drive versus a gearbox. So easy to carry spare belts. Hybrid makes so much sense and I really like that you do not have diesel engines and generators. Fewer parts that need maintenance is so much better. Going through the maintenance difference would be interesting.

[@christopherledesma8435]

I do see a few problems with the electric motor connected to the shaft after the gearbox, using a belt. 1. If the electric motor gets stuck (internally) that will hold the driveshaft and will not let the engine run, unless it breaks the belt. 2. Based on the information provided, The electric motor belt will be running every time the boat is sailing, that will drastically reduce the life of the belt and the belt pulley. Why not using gear system (with a manual disengage) to connect the electric motor to the driveshaft, it is more efficient and reliable?

Thanks for another great video. Love the hybrid. It would be nice to cover the evaluation of different prop types and how this is optimized for the various modes, including regen. Cheers

I agree that parallel hybrid is more efficient if you are a power boat and always motor. For a sailboat, where you rarely motor, serial would be more efficient. This is because in serial you can more closely match the engine size to the generator size.

One of your best vids of the kind. Well done!

[@GR8TDUCK]

VERY cool. Can't wait for you to get out there!

[@terrymeikle195]

wow! so envious!😄

[@edwardcassel3789]

Congrats to you both. It has been a long journey but you guys are finally here. Question, What is the MTBF for the electric motors? Ans have ya'll factored that into the cost. I'm sure you have tried to cover all of these questions, bc I've been watching you guys for a very long time. Good luck and may you're travels be rewarding.

I don't know the answer but is should be available online without too much fuss. This Beta Marine hybrid has been used in ferries and narrow boats for decades and is considered very reliable if that helps! Curious Minion

As they say keep it simple, another great review with a multi type system

[@Outdoor_MED]

I am stoked about your boat!!! 😁

Great introduction to the system. 48vDC is starting to get traction in the trucking and automotive industry also in time more system components will be ‘common’ place, but nice to still have ye olde 12v for RV style appliances that are readily available.

Tesla is going to 48 volts in their new cars

[@stephenhawkx]

Yes Tesla cybertruck in production now is 100% 48V architecture. Soon the whole industry will start transition away from legacy 12v.

[@stephenhawkx]

We will see! Switching much faster than expected imo
