Re: [electricboats] long-tail boats

If I understand correctly, you want to use the design of long tail boats like this, but you want to switch from a gas engine to an electric motor:

If you want the same performance, you want to go with around 1/3 the rated hp of the gas motor. So for example, if you had a 20 hp gas motor you would want to have around a 6 hp electric motor, which is about 5KW electric motor.
The problem you will have, is that you will need a very large battery bank, unless you are only going on short rides. It is possible though.

Hi, 
Sounds like you have a sail boat and you need to have an extra long shaft to reach below the water. All motors  are standard long shaft or short shaft. Or you can buy a pod type that mounts under your boat. You may need to design a mount that can extend down when you wish to motor. If you have a picture you could send  I would have a better idea. Or post it on the Facebook page and ask for ideas.

Regards
Phil

Hi,

I was wondering what would be the best electric motor for "long-tail boats" (in replacement for gasoline, diesel etc. motors; these are outboard motors altered to extend their propellers far from the rest of the motor)!

Thank you in advance for your comments, suggestions and tips.

Best,
M
