Re: [Electric Boats] Electric Propulsion Torque & Thrust

 

GeoG,

Two Years ago I equipped my 5,000 lb displacement boat and have sea trial data if you are interested.

Greetings to ALL,

I had a very interesting conversation with a Westerbeke Distributor, 40 yr man, knows quite a bit about marine engines.

I asked him if he could describe the differences regarding Torque, Thrust, Propellor Design, when comparing ICE & Electric Propulsion Systems for marine applications, and he could not.

I want to decide between a 30hp ICE & an Electric Propulsion System for thrusting a 15,000 lb displacement hull at 6 knots for 4 hrs/day.

Does anyone have a good understanding on this subject ?

Best Regards
