The other day on my P38 I got caught in some 20+ knot winds and, since we had a long way to go and my wife was getting uneasy, I decided to put a reef in the main. On a P38, as well as on a P36 and P37, the boom is an Isomat and the reefing lines are internal within the boom. Unfortunately the aft line (which runs through a pully system in the boom)became untied from the boom and slipped through the cringle. When I pulled the line to reef the sail the line disappeared into the back of the boom. My guess is that I have to remove the sail, remove the boom, remove the end fitting from the boom and finally try to recapture the line. Anybody got any better ideas,
