We tie ours on the boom
The jiffy reefing line comes out the aft end of the boom. It goes up to the reef point, then down to the boom on the other side of the sail. We tie it around the boom with the tightest bowline we can manage.Actually, we have two lines, one for each of two reef points. But they are both attached in the same way. Of course, the higher, second reef attached farther forward on the boom.DavidLady Lillie
