I don't think fuel
saving is the main issue.
A simple plug-in electric propulsion
system for a light day sailer or racing boat
is surely cheaper than an inboard diesel
. And lighter. I think that actually does sound like a good use case.
Another good use case might be an ultra minimalist long distance cruiser on a really small boat
, who really doesn't motor
except to get in and out of harbor. Now that's a case where solar
can actually do something useful for propulsion
. Like Pardeys plus a harbor engine
But for normal cruising, I certainly agree with you. As for myself, I just motored three days and nights (three days and nights straight! I certainly owe my Yanmar
a beer) from Greenland
during a dead calm -- a really dead dead calm, or very light contrary breezes, which is often the only weather
window between shrieking gales you get up in these latitudes. A big tank of diesel fuel
is really the only feasible way to do that at this stage of development of the technology.
