Let's see now.....
I've been hit by the mast once (don't ask), the boom on a J22 3 times on the same day (slow learner) but never been caught by the jib shackle. I raise, lower and change the jibs (gotta have some fun right!) You do have to exercise discipline, sheets under control when any one is forward. An out-of control sail says a whole bunch about the crew don’t you think? I use one set of jib sheets for all jibs including the spanker. Makes for Faster changes.GregH23 Faster-
