Taking this off on a tangent: The only time I ran into trouble in my 30 year sailing history with the mainsail was using a power winch. The second reef line was caught and I blew a sail (didn't get any of that deposit back). Since, then I check the reef lines. Any other pearls, on rising the main under power winch?
-- ps - if you place the winch handle in the power winch and then push the power button > you'll only do that once. Hopefully, you still have one good arm left after this. It's like reaching off the back of the boat and holding the handle of mop bucket to get some water while you underway > you'll only do it once (if your friends circle the boat back around to pick you back up)
