Size Range & Diesel Electric Drive With the style rig I show here I do not think a vessel less than 40-45 feet qualifies. I agree there. I am particularly interested in this latest 'rim-drive' technology as associated with electric propulsion (diesel-electric). http://www.yachtforums.com/forums/technical-discussion/3961-rim-driven-propellers.html And I believe there is a case to be made for a less sophisticated kevlar belt driven rim propulsor in a jet-pump configuration....looking at that now for a smaller RIB adaptation (actually the one or two tenders for the 65 gamefisher) http://www.yachtforums.com/forums/technical-discussion/4470-jet-drive-vs-prop.html I had a pretty serious inquiry on a 85-100 foot version of this design (without the fishing gear) for fast cruising with small crew, but it fell through. Now talking with a prominent gamefishing group about the concept.
