I am not up with this from a boat point of view, but I would have
thought that either angling the tail if the mill so that it
self-slowed as the breeze became stronger, or using the tail to brake
the blades, would have been simple enough. It's been done on pump
mills for a long time.
Another opion would be _literally_ feathering the the blades, so that
they are not spinning, if the heat cutout cuts in?
I can see why the heat cutout needs to let the genset open and allow
freewheel, rather than close and stop it. Short circuit generates
large currents and little roatation for cooling, and could make things
worse.
I'll have to look into this further. The few times my thermal
switches have activated, they have served to stall the blades
rather than to let them freewheel as I recall. But if
I recall correctly, pulling the mill out of the wind with a string
has been a standard technique for many products for a
long time.
