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.

[@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

[@gonewiththewynns]

@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?")

[@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.

[@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!

[@colourful64able]

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

[@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.

[@stevejones9788]

That's a really impressive system Really efficient and at the same time built with kit that is easily worked on by a normal mechanic. Love the fact that the engine doesn't have electronics on it that can only be worked by a dealer.

[@fredbugden3511]

The down side is what are you leaving on the table in terms of power and fuel efficiency but not going common rail. The software to diagnose those system , while proprietary is usually available somewhere for those willing to search.

[@gonewiththewynns]

True, but the pressure needed for the common rail system is high enough to amputate a finger if you don't know what you're doing when you service it. For owner service and repair & parts availability in remote areas, I'll take the simpler system & give up a little power. Especially when Nikki and Jason plan to rely on the electric motor as much as possible. Curious Minion

[@chrismulvey49]

What is common rail?

[@TheRealSasquatch]

@@chrismulvey49 Common rail diesels use a high pressure pump (30k psi?) feeding a common rail (pipe) with solenoid operated injectors controlled by an ecu to spray the fuel into the cylinders. Direct injection diesels use a relatively low pressure mechanical pump/injector each fed by separate fuel lines, usually driven by the camshaft.

[@johnmayer3433]

@@fredbugden3511 One problem with common rail diesels on blue water boat is their need for very clean diesel. So you need some installation (filters) to make sure that what you are feeding into the high pressure pump is best quality. One more system that needs maintenance, spare parts a.s.o. On a boat moved 95 % by the wind I don't see the advantage of having a common rail engine.

[@cliffdavis5244]

[@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.

[@thomasw5430]

[@CmoreTruth]

I've said it before you two do a fantastic job with your channel and editing. Super duper ❤🙏😎

[@MrJohnBos]

The drive system looks cool. I love the idea of running quietly on the electric motor for 2 or 3 miles before hoisting sails or, vice versa, dropping sails and quietly entering the anchorage or marina. Also great for fast charging the big LiFePo4 battery bank from empty to full in 2 hours if necessary.

[@LoanwordEggcorn]

And the key thing is that all of the electrical energy used to motor can be recharged simply by sailing. So motoring becomes WIND POWERED. This is working in harmony with nature MUCH better than burning fossil fuels. In reality, most people with electric drive sailboats use the motor to get away from the dock/anchorage, raise the sails, then use the sails to recharge the battery for a while by hydrogenerating. After charging enough, the motor acting as a generator is disengaged while under sail. Coming back to dock or anchor, the electric drive is used to motor again. And battery can be recharged by solar, shore power, etc.

[@peace_oceans]

I love the design ethos of this HH. The engineering fundamentals kept simple & accessible with an elegant hybrid interface. Excited to see the testing etc. Great job HH, my fantasy yacht league ties you guys & Outremere as top choice!

[@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.

[@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...

[@raybonecrusher4516]

Looks like a great system. I'm wondering how trouble shooting will go once you get away from the dock. During electrical storms can you isolate your electrical components to keep them from damage, and if the controls damage can you limp in manually ? Great video today. Ray

[@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!!!!

[@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.

[@justlookin3]

Can you imagine that RVing turned into this sophisticated catamaran? Wow!

[@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

[@FrankDoucette-q9j]

Those HH engineers are sharp! Again, I doubt you’ll need the spare belt in an emergency, but good to know it’s there.

[@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.

[@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.

[@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,.

[@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.

[@doogl2331]

That was really interesting and the engineer dumbed it down so we could all understand. Now I understand why you chose a hybrid.

[@Boris_Chang]

To me, this is the perfect setup: harnessing the power of the sun and water flow for energy, storing it in batteries, and having diesel backup for when there isn’t enough sun. Quiet, eco-friendly sailing, with a little range extension of electric motors, powered by diesel engines when the battery array is running dry.

[@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!

[@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!

[@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.

[@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!

[@codegame027]

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

[@jeffmorton9220]

I missed seeing Nikki on this episode. I could hear her voice in the background, leaving me to believe she understands the workings of the hybrid drive system quite well. If two heads are better than one, then once the Wynns are out on their own, they'll be better able to diagnose problems that inevitably arise and be dealt with. Still, I feel that in many ways, Nikki Wynn is the reincarnation of Audrey Hepburn. Her smile or even the sound of her voice, adds an undefinable energy and appeal to the episode . Despite no Nikki, Jason and their factory rep gave an easy to grasp understanding of the basic capabilities and limitations of their boat's hybrid battery/diesel power system. Thanks, guys!

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?

Super introduction to hybrid propulsion on a sailboat. Thank you.

[@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.

So cool to have backups to the backup!✌️💜

Can't wait to see you guys get ON THE WATER and try out this magnificent machine full of technology. I"m sure this type of boat is at the forefront of many future boats to come.

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.

[@matjon1234]

Even if you don't need your motors you still need to run it for maintenance for like 30 minutes a month. Or it might not work when you need it. It should also be run with load not on idle. Love you two. Happy sailing.

1:30 I love your comment and your passion behind it. I feel the same way. Was hoping to meet you at Annapolis but I’m guessing you’re going to be on the other side of the world celebrating your anniversary. Congrats! I found and fell in love with HH 2 years ago and I am excited for you getting this fabulous new boat.

[@bobcombs9942]

Can’t wait to get started working problems off the new boat.can’t wait.

👍Looks good Jason. Thanks for the rundown on the system. Plenty of options to play with there 💯. New batteries currently in development will deliver extended range in the next few years - ie: Aluminium Ion battery by GMG (and zero fire risk!)🇦🇺

[@angelmorales7468]

I love the regeneration with the boat under sail only, it produces electricity with the props turning. It wasn't mentioned in the video but I'm only guessing that it actually helps with speed since the props are not fixed causing drag with them spinning freely.

Incredible! Now if the autopilot was connected to the fish finder you'd have it all!

[@fredbrooks8347]

😅You guys are true Trail Blazers . I am really impressed at the jump/change the two of you are making and are taking us along on this journey.

[@pfalzgraf7527]

Fab episode for such a "dry" topic! But if you're interested, dry doesn't bother you (well... me).

[@kenpierce9466]

Love the videos Jason, I am not a sailor, but I love the tech side, both the electrical EV, diesel and rigging. I can see that you'll be getting a whole new set of skills to do remote Tshooting. None of it would be possible without the awesomeness of satellite and the internet. I think you guys are uniquely equipped socially and adventure mindedly (is that a word?) to be pioneers for a whole new genre of sailing. Best wishes you guys!

Funny watching Jason interview his younger doppelganger. Also Leo from the Sampson Boat Company is using the same motor setup in Tally Ho.

[@smartbiz888]

So exciting to see this build come together... Thanks for keeping us abreast of the latest and the tech behind it all... You guys are the greatest on land or on water...Keep on keeping on...

[@PeterDavila-mx9ni]

Great video, thank you. I'll be watching it a few more times. Lots of good stuff discussed.

[@TimmyMoza]

Thanks for that walkthru and detail. Thats pretty awesome and the redundancy especially valuable when you are in the middle of the big pond with no land in sight… really cool! Oh also forgot to mention that this is 100% serviceable pretty much globally… well done!

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.

Love that color!❤❤❤
