Everything I see about electric
motors is "maximum" data.
These are, after all sailboats
The have their own propulsion
For a twist on electric
and renewable power I'm thinking more in line of using an electric motor
for "assistance" to the sail.
Just a little more power . . . a little more movement . . . a little better pointing when needed.
When the sailboat is only moving 2+ knots, maybe the electric motor(running about 1/4 speed), would make about 3-4 knots achievable, which will get you to your destination
"a little sooner".
When the sailboat can't quite make the high-up heading you're striving for, the electric motor(running at 1/4 power or so), will help make the heading more possible.
I'm not necessarily talking about the "electric" motor
being the main source of auxillary power(although that's what I'd like).
BUT . . . rather using the electric motor
at a greatly reduced power-level and coincidently using a solar
panel to maintain(or better) that particular level of electrical
Is it realistic to use self-sustaining electrical
power to make the sailboat work just a little better?
