Not for me.
Not enough sun here boys, and none at night.
"Remove your portion from our oil burden while silently cruising into distant harbors".... what????
Beware you don't get swept along with the great global warming cabal.
In blazing heat, through the doldrums, with solar cells everywhere, an 8 kW electric motor will move your ship ok, but from where would you get the energy needed... 8 kW+ ?
And how fast would solar cells really move a 10 ton ship? It's not the power of the motor that bothers me. they could list 100 hP in there. The vital questions is the energy source, not the power of the motor.
