Yes very interesting. Saw this story a few years ago. Got me thinking (dangerous thing to do sometimes).
Hmmm, My boats got an un-stayed mast
. I've got electric propulsion
. My boat
can move 3 knots (calm conditions) using just 900 watts of power
. All I would need to do is ditch the boom and sail. Cover the deck
with solar panels
and rig up a wind turbine that could rotate around the cut down unstayed mast
on bearings. Then I say I had better stop thinking about this.
