I only mention the lectric winch option because a genius at our marina rigged his halyard to his electric anchor windless and hoisted himself up in the bosun''s chair.....which worked really well until he went up further then the remote control unit''s cable. The plug promptly came out of its socket and the winch stopped winding...with him about 15 feet up the mast!
Fortunately this was actually in his pen....with more then a few people watching in amusement. We let him down, eventually (promises of beer were involved, as I recall). He had a good sense of humour about it, he was trying to change the bulb in his steaming light and thought the cable on the remote would be long enough....
