I have been speculating about a diesel-electric propulsion for a smallish sailboat. Does anyone have links to, or experience with, small electric motors that are suitable for continuous use - most of my googling finds bow thrusters and other extra machinery. There are electric fishing motors, in the one horsepower or less class. Maybe enough power for an under twenty foot boat. Not good on a windy day. I am thinking of a fairly small engine, say 5-10 Hp, to be used mostly in manouvering in and out of marinas, and occasionally coming home from a calm sea. Would it make sense to mount the whole engine on the transom-hung rudder? That way it could turn with the rudder, and give good steering in both directions. When not in use, it could be lifted out of the water, so I could use a decent size of propeller for it. There is the tried and true outboard motor. Hanging stuff on the rudder sounds like a poor approach to me. Not to mention ugly. Would anyone care to shoot the idea down before I get too attached to it. Shouldn't be too hard. Casady |
