I sail an F36 alone often. Hauling that up takes a lot of work and I can se where making or having something powered would be the way to go. As far as bringing it down I made adjustments to the lazy Jack system adding a point further aft on the boom. This year I setup a block and tackle to lift the boom and tighten them so all I do is center the boom, haul up on the tackle and it sets the boom tight. I run the main halyard around the winch lower it in 2 stages at first, get that all tied in place and then lower the rest without an issue. If you need photos let me know.
