I myself am glad that we are moving toward electric. Not having to deal with out date combustion engines is an all right deal...It great to hear that re-genitive capabilities are now here also ...
Dolphins aren't attracted to your motor. They're riding your bow wave. They'll do it with any boat.
I HAVE A 1970 MORGAN 22 SAILBOAT IN GREAT CONDITION AND THIS LOOKS AWESOME! I LIVED IN SANTA BARBARA COUNTY BY THE FLORIDA KEYS NOW.
an electric motor on a sailboat without the sails is just as much fun. it's quiet and smooth and no heeling
Ok, I've been lookin at these electric motors in boats. First off , I think they are a good replacement for sailboats but the people who demonstrate these motors are electric motors worst enemies. They don't talk about what came out of the re-powered boat (ie. weight of motor, Hp, fuel, range, speed, consumption etc.) Then they don't give much info on what they put in (ie. weight of motor and batteries, range at different speeds with installed battery bank, how long to charge with different charging options, PRICE) They go on and on about how is better but don't show how. this would tell me that it over-priced and not ready to compete with current gas or diesel motors
Interesting. My sailboat is wind powered.
Very cool. What is the range of the electric motor? Also, did I understand right that you can recharge the batteries while you are underway under sail power?
no
Yes. Called regeneration.
I've built a electric motor system for my Alberg 30 and I love it. The only thing that would make it better is a throttle like yours. Do you retail the throttle control or know where I can purchase one? Thank you
That’s something I Haven’t found either. On the other hand, I’ve already used to the knob.
@ 2:16... no, no, no, you do NOT have full control over the sailboat while leaving the helm with running motor and setting the sails up....
What engine is this? Thoosa? What kind of battery bank are you using?
I suppose you can charge the battery with an on-board diesel, right. Right?
Or portable gas generator, wind and solar.
I like this idea but if you are a blue water a sailor there well come time when you need as much prop power as you can get. To me having a good size gen, to aid in the power of the electric motor would make things feel safer at sea.
Nether the less its a great idea with some work could make sailing as well as motor yachts a much cleaner vessel to the sea life and ours.
Freddy Stone hydrid looks like the way to go but I haven't seen any.

You can find electric motors as big as any deisel that might be mounted in a sailboat, up to 500+ HP. The qauestion is the range if the boat has only batteries for storage.
Electric cars are a thing. Electric semi trucks? Nope. Diesel is just the best application for the heavy, continuous load of pushing a displacement sailboat through the water.
does it recharge the battery
yes but fairly insignificant on a monohull about 100 watts at 6 knots and double it for each additional knot
So many sailboaters just motor off the hook and back on, and only on nice days. This might be good for them. I have yet to see a video where an electric powered boat goes into 25 mph wind and five foot waves. Not enough torque on that motor. Only good for flat water and light air. Want to try using this to keep off a lee shore in a blow?
The motor has plenty of power. More power than a diesel any day. How much range is the issue. If the motor is supported by a diesel generator in a true hybrid configuration then it will outperform a diesel in any conditions.
jameslambden thanks for the reply. Is there an inherent advantage in using a diesel generator to convert the energy into electricity and then into mechanical energy as opposed to turning the prop directly from a diesel motor via a prop shaft?
Below Approximately 75 % of hull speed, the hybrid will be more efficient, Above Approximately 75% the diesel will be more efficient. Percentage of hull speed where equilibrium occurs differs for every boat, propeller, shaft seal, electric motor, diesel motor, bottom condition, number of through hulls, etc. etc. I also refer to this speed in my book as natural boat speed, which can be quickly estimated by taking the square root of the waterline length in feet, the resultant being in knots
At 3 knots, the Catalina 30 only needs about 500 watts, so it is more efficient to deliver 500 watts through a battery than it is through a diesel because a diesel is very inefficient in its bottom end. At the natural boatspeed of a Catalina (square root of 25 foot long waterline ) 5 knots the C-30 needs about 3 KW and at this speed the diesel becomes more efficient because it doesn't have to convert the mechanical energy to electric and then back to mechanical.
jameslambden thanks that was a sensical answer. I understand that diesels need to be kept running at higher speeds in order to maintain the pressure necessary for continuous combustion.
Great idea, who would I contact to learn more about this system?
+Ron Armacost; Would this system be compatible with flight, like Ultralight aircraft? Would a wind generator work with this system?
+Ron Armacost No and Yes
What gear reduction are you using?
Depends on your prop, hull speed and motor used.
do that under normal condicions
with waves and wind...and you are lost
so much resistance from the staus quo
How do the batteries hold up if you only sail a few times per year?
Add a few solar panels to keep the batteries charged. And you can use the excess power to power other devices onboard.
With Lithium, 2000 cycles or more.
Obviously it isn't as good as he portraits. He hasn't any questions that has been asked. It might be good for in the harbor but can you imagine how many batteries you would need if you had to motorsail for a couple days.
If your gas or diesel engine breaks down, almost every marina can help get it running again without too much difficulty. Loose the electric motor or its controller, good luck with that
*****
Until you run out of juice. Battery technology has to improve a lot before you can attempt long trips or if you don't mind sitting around waiting for the sun to charge the batteries again.

Another 50 years it'll get there
Mazda rx7 yeah but on a small boat like that I'll also have a backup 50 horse outboard just in case
recharge with solar panels ''Obviously'' no gas stations out at sea for diesel.... :)
@@RobertDeloyd fat good that will do you if you're trying to stay out of an encroaching storm system
our centaurs Volvo engines 40 years old still perfect that electric motors toast in 2 years the 10 batteries toast in 2 years centaurs had one full tank of diesel in a year been out every week your setup lasts 2 hours MAX our centaurs tank will do 20 hours easy
If it worked they would be every ware.
That's what they said when the first gas engines were used.
Allen Conga dude this is an old video. where are they then????????????
Never said this particular guy,,, but have you been asleep in class? There are lots of electric reposer kits for yachts, including systems sold by West Marine, ever heard of them? Here's a 2 second search I did, www.google.com/#safe=off&q=electric+motor+sailboat
Allen Conga You can still buy muskets too where are the boast in operation?
You're right it's impossible... So don't do it then.
