Having installed these kits on other boats, I am a bit experienced with them. On my own
boat ( a 40 foot
trimaran with 300 sq. ft. main and 600 sq. ft. jib) I use
Harken ST40.2 winches for the halyards and main sheet, and two ST 50.2 for the
jib sheet winches. My suggestion is to
purchase a Milwaukee right angle 28 volt drill
motor with winch bit, or to
purchase a "Winch Buddy", which is the same thing, but with a neoprene cover that masks the fact that it's a Milwaukee right angle drill. Try it out first before committing to an electric drive winch. I think yu will get the picture immediately. Then, should you really get it, buy an additional
battery pack. If you don't like it, you will be pleasantly surprised at how easy it is to sell on Craigslist to another sailor. I only use the drill motor if I want someone to send me up to the masthead without cranking me. Otherwise I use it for
work. The first two pics are of a
Harken I installed a year or two ago.
