- Aug 5, 2010Unless very shallow draft is important, Rescue Minor isn't a good choice
for electric power. The "fuel" for an electric motor is very heavy and
bulky. If you put a powerful enough electric motor in Rescue Minor to give
her the performance Wm. Atkin designed he for you could only put enough
batteries in her to have a very, very short range; any more and she'd get
too heavy to perform well. The most sensible thing to do would be to put a
small electric motor in Rescue Minor and run her as a displacement speed
boat. Weight isn't so important in that speed range, and the small motor
won't need as many batteries for good range anyway. But Rescue Minor's
hull isn't particularly efficient at displacement speeds, and electric
motors work most efficiently with large propellers, and Rescue Minor
doesn't have room for a big wheel. You could do an electric Rescue Minor,
but I don't think you'd be very happy with it.
Better choices for electric power would be some of the Atkin boats
designed to get along with little power. The ones intended to use
relatively slow turning engines like the Universal Fisherman should be
able to accommodate a big enough propeller for efficiency. If you pay
attention to weight you might end up with an electric boat that'll outrun
the typical heavy displacement electric boats, yet still have good range.
The Fisherman with reverse gear weighs almost 300 lb., so replacing that
lump of iron with a much lighter electric motor gives you weight allowance
for a good start on a battery bank before you start adding extra weight to
the boat. Here are a few boats I think have promise:
