Has anybody ever actually done that -- winching somebody back aboard a cat using mainsheet blocks? I am trying to picture the scenario in big seas and wind, one person on the boat trying to hold onto the person in the water and at the same time trying to keep the boat headed into the wind and at the same time rigging this makeshift hoist and then getting the boat turned so that the boom is on the same side as the overboard person, and figuring out how to attach the hoist line to the person, while trying not to capsize, etc., etc.

And, of course, when one person falls off the boat, often this results in the boat capsizing right away, which creates a whole new set of problems.

Maybe some of the experienced Worrell sailors should start a whole thread devoted to worst-case scenarios and suggestions for dealing with them. Might save a life.
