Sailing last weekend was raising the main..got a little tight at the very top so I put the line on my winch cranked it and the line overlapped on itself around the winch. It was stuck. After a second of "uh oh" i grabbed a screwdriver to use as a marlin spike and battled with the line to free up the trapped end to free it. I was lucky it wasnt very windy. How does this happen with the line wrapping over itself? Yes I wrapped it clockwise by the way.
