It’s interesting to see a company represent the value of regen capabilities based on a use case. It’s not like that capability adds complexity or cost to a system, only to the R&D and design load. So tell me they’re not interested in investing the time in regen capability but somehow all are interested in being considered the best at what they do. Ocean Volt is the only company that seems to understand that a successful implementation of this technology might not fit exactly to how people use a boat now, but it might change the way all people use a sailboat - in the same way that the combustion engine changed automobiles and human mobility.

@mymobile5014 8 ай бұрын

Ocean Volt may well be trying to be the best at what they do but come on, £27K for a motor for a 10 metre sailboat? You can actually buy a sailboat for that money. Or 6 diesel engines. Nothing can justify that sort of price.

As was said in the video, doing regen well in a boat is NOT just software like it is in a car. It requires different propellers and waterflow characteristics.

Oceanvolt's servoprop saildrive sounds terrific but in my case the extra $10K, over the Electric Yacht option with much lower regen performance, is far too much. I suspect the same will be true for most who cruise on a modest budget.

Would love to hear more about your set up as we couldn’t find ANYTHING on their website about test boats or sea trial numbers or regen tests.

@svkotona 8 ай бұрын

@SailingUma Happy to share. ePropulsions does kinda bury the Performance Bulletins. At the very bottom of their homepage, under the Service heading is a link Performance Bulletin. We installed the Pod 3.0 Evo in our Beneteau 235. While regeneration was a consideration, for us it was more the quiet, and the lack of maintenance. My wife wanted to be able to single-hand the boat but didn't want to have to deal with a recalcitrant outboard. So we went electric and don't regret it at all. The complete system includes the Pod (3kw direct drive motor), motor controller, 4kw 48v battery, throttle, display and cabling. It was mostly a plug and play install. Drilling holes in the bottom of your hull is slightly unnerving the first time you do it, but after that it was pretty straightforward. As far as performance, we were delighted. 1kw (with a clean hull) would keep us at 5kn for about 4 hours. Since we use this boat primarily as a daysailer, and are rarely more than 10 miles from our home port, that was plenty of power to get us back if the wind completely died. Our max calculated range was about 25 miles with just the one 4kw battery. We never pushed it that far; we prefer to sail when possible. One thing I will say about their regen system is that it does work, but. For our use case, inland lakes with a boat that has a 22' waterline and a hull speed of just over 6kn, it didn't really do much. That may be due to the prop being optimized for thrust rather than regen. Oceanvolt definitely has the tech edge there. The most we saw was about 100w at around 5kn and usually more like 75w. But the ePropulsion regen chart (on their Pod page), made it clear that below 6kn you really weren't going to get much back. On a larger boat that can maintain say 7kn or 7.5 kn, and do that on a 200 mile passage, it would have more impact. Happy to answer any other questions, either here or offline.

For me, three companies stood out. Remigo is perfect for a tender or hobby sail boat (and the other similar company... can't remember the name). Combi is the perfect intermediary solution for those who don't want to go fully electric just yet, for what ever reason. And, despite the price, Ocean Volt is on top of the game for fully electric, regenerative propulsion for long term cruisers.

What a marathon! After watching it I am even more impressed with the pioneer Wylie 44 that I spent two weeks sailing the Bahamas on 16 years ago. It was based around a large, slow turning propeller of optimum shape for efficiency in the 4-10 knot range that the boat regularly delivered. It was always on. When sailing you had the option to have it slowly turning producing no electricity and with essentially no drag, or with a simple move of the throttle you could feed as much electricity into the battery as the system was capable of absorbing or pull power from the battery or from the generator in diesel-electric mode. Out of the entire 40 exhibits in the show only one company followed that philosophy. It is superior to our pioneer system because it had a 360 degree rotating drive and more advanced controllers. My impression was that only that company and Ocean Volt really care about the people like you who want to regen while crossing oceans. The others read their market correctly, because most sailors just want to have an afternoon in the sun and be able to brag about the high tech in their boat at the bar afterwards.

@southernfriedkiwi7726 8 ай бұрын

I appreciate how honest some of the company reps were, in regards to the repeated question of "regen". Regen only starts to make sense over 8 knots, but preferably 10. The point people have made about Uma not being worthy of this current gut job, was that it doesn't suit your needs/requirements, going forward. If regen is so important, then it makes more sense to get a larger boat with more length at the waterline(faster) and more real estate for batteries, as well as solar.

@SailingUma 8 ай бұрын

We can generate more power than we can use currently on Uma when offshore sailing. Sailing at 5kts we break even, anything faster and we’re charging. Of course a boat that can average 10+ kts would be sweet. But we don’t have $1,000,000 just lying around burning a hole in our pocket.

@southernfriedkiwi7726 8 ай бұрын

@@SailingUma You still fire up your generator though, because your energy storage is depleted very quickly, when used for(very slow) propulsion. My point for a larger vessel is also about having significant space for lifepo4. Generating power through regen, is kind of moot, if you don't have the space to store it. Also, regen math doesn't really add up unless you're on long passages with great daily average kts, which one of the reps brought up. At the end of the day, you guys can do what you want, based on eco ideals. Everyone else though, has to live in the real world where none of us get free tech or significantly discounted tech because of a "channel". The cost in the real world is ridiculous, when compared to ICE tech, with way less practicality. I like the idea of hybrids. I like the idea of quiet anchoring and leaving marinas. General propulsion needs though, can't be seriously replaced with batteries that absolutely have to be switched out in X amount of years, at huge expense.

@donnordstrom31 8 ай бұрын

I loved when you said to the guy at Epropulsion that the 1KW engine isn't going to bring the dingy on plane and he answered "no, definitely not!" and then he made a nonsensical statement saying "it's all about moving the boat efficiently" when in fact bringing the boat on plane IS the most efficient way of using propulsion energy! From this alone one can deduce that this whole circus is a lot of marketing BS. P.S. Electric motors ARE more efficient than ICE motors, that's also a fact, but you'll need to add a lot of weight to a small boat from a huge heavy battery to get a motor powerful enough to get you on plane. Someone needs to calculate a golden ratio for his/her application. In other words...it depends on what your application is.

I have built electric outboards before and in the interest in regen, its almost like you need a different unit that is really designed for regen other than the unit that is built for boat drive. Its great to have one unit to do both but I think the regen characteristics would be one that has more prop blades and is designed to spin the motor generator at a high rpm while the unit for moving the boat would be designed with less prop blades and spin at a lower rpm for energy consumption efficiency. Hard to get regen out of a unit designed to drive the boat. Another solution would be to make an outboard that has a high speed and low speed gear drive in the lower end that could be switched back and forth to put it in regen or drive mode. I don't believe anyone has looked at that since regen always seems to be such a low priority to the manufacturer. Every opportunity to make electric power for storage should be considered when doing long distance sailing from prop regen to solar to wind. More power input may allow less battery capacity which is money weight and space. Best of luck to what you end up designing. Hope you find a sponsor there to try out their products and showcase them for both you and their benefit. Love you guys and your channel.

ocean volt isn't the only ones finally learning why planes have props facing forward (puller/tractor config) vs facing backwards (pusher). the 2 biggest reasons having the prop facing back is convenience in engine placement as well as less prop snagging on ropes, seaweeds debris, rocks etc, but facing forwards is maximum efficiency since there's nothing in front of the prop to take wind (or water) away. it's just more susceptible to damage, snags and drag. some twin engine planes also feather their props in the event of a single motor loss to prevent weatherveining causing a flat spin due to drag. ocean volt got it right for a static mount. i like the EPT better since the prop is more efficient. either way, if your facing forward, go feathering. facing back wards, furling.

I was at Mets 5 years ago. Such a different scene than the typical USA 'boat show'. The companies you interviewed were obviously well versed in what they were trying to market. Great information.

Really enjoyed this video. I learned quite a bit myself. Big cudos on the music chosen and the Kika variance waking . That was fun and kept this kind of boring topic interesting. Also, it appears that in some of the interviews you knew more than the unsuspecting sales person that probably took a youtube channel for granite. ❤

Fantastic presentation. All companies interviewed had their own angles to the same question, Combi looked good but would weight and space be an issue? EPTechnologies looked good until the regen comment, Kika spoke volumes with the look @46.24. Omega Grey had a very good presentation too but Ocean Volt seemed to me to have won this debate so far. Again, I must compliment your research and presentation. Looking forward to what comes next! Stay Safe & Fair Winds!! ☘

😮THIS episode was mind-blowing and so enlightening. I am certain the average person has no idea how far this technology has come. I live in Alberta with a premier who is so addicted to oil and gas, it makes me want to cry. After shutting down Alternative Energy companies, and promising future electricity powered by gas, I feel we are reversing into the dark ages. The knowledge I have gained from watching this video, gives me hope. There must be change! I feel it is happening too slow for my liking. I am retired now but I so want to leave this earth with hope for my young relatives and future generations. The few moments I spend with you watching your adventures and the pure happiness you exude, brings a brightness to my days.❤🎵🐻🌎🌠

Stick with that premier, she knows much better than you! P.S. Let me phrase it differently: you don't know what you are talking about!

Great video, one thing you may not know is regeneration acts differently for Permanent Magnet motors and Asynchronis motors (two common ones). The difference is an Asynchonis motor can be allowed to freewheel (just spin without resistance) and a permanent magnet cannot. The Pod motors from WaterWorld are permanent magnet and they have excellent regeneration but its not yet released because fringe scenarios still need to be accounted for by the programming. Specifically, preventing regeneration when batteries are full. A folding prop is a mechanical way to prevent regeneration and is the suggested method for sailboats but other options may be better. Regen is a complicated problem but long story short all electric motors can do it. Next 5 years will see a lot of optimization in this space.

Great video! I am quite fond of Elco, my father used to work very near their old PT boat facility in Nyack NY. Their outboard motors are beautiful, but the right angle drive could be a maintenance/noise/efficiency issue. I do think that direct drive systems are better overall. I'm experimenting with an "on the cheap" Newport Vessels 62 pound thrust trolling motor (on our Compac 23). While weak, it is incredibly light and quiet. Electric could be the future, especially after a long battle with ethanol fuel and other issues with a Tohatsu 6. After finding a source of non-ethanol and myriad modifications it is now perfectly reliable, but it seems there must be a better way.
