I saw an adaptor at Annapolis. It had a 5/8" hex shank on one end and a
winch star on the other. I am sure it would require a lot of torque.
The
demo was being driven with a 24V low speed right angle drill. Similar to
a
Hole Hawg but battery operated. It was red so I assume it was a
Milwaukee.

The thing is, electric winches up to the mid 50s use a 3/4 HP motor geared
down to about 50 RPM. I don't know of a hand drill that can deliver that
much torque so you will have to do the last few turns the old fashioned
way..

I suspect those winch motors were turning the drum directly. The drill
motor would be using the winches gears.

A person can exert only about 50 lbs with a one handled winch handle. Maybe
a bit more if he grunts and is big. 50 lbs x 10" = 500 in.lbs

A Milwaulkee 18V cordless drill spec gives 600 in. lbs of torque. Maybe it
is enough.

You would probably want a short tether on the end of the drill to clip to
the deck and provide a reaction force (otherwise you would still have to
provide 50 lbs of force on the end of the drill to stop it spinning!) I do
recall the "Wincher" used such a strap but it was $2500 or so!

I suspect that this drill is just enough grunt for the job, but I wonder how
long the batteries would last tacking up a narrow channel? Perhaps the
corded one would be better suited?
