My wife uses our winchrite to haul us up the mast
and then on our in-mast furling
for our main and mizzen. The first generaton units had bugs to work out, but they have upgraded their gear
box and motor
for the unit units and we have been happy with ours. The problem with the drill buddy or simular device is that the RPM
of the drill isn't matched for the low end torque of the winch applcation so it sucks the battery
down quickly and then when you try to use the drill in reverse for a two speed winch I've seen the chuck losen up.
