Just purchased an S2 28 footer model 8.6( my first sailboat), Am perplexed by the reefing system. 2 lines for the two reefing points which go through the kenyon boom, exit the aft end and go through the reefing cringle to the other side of the boom. These originate at the mast and go through a block at the mast base and to a cleat higher on the mast. When rigged as per the prior owner, even with the lines totally let out, the lines are too short and prevent the main from being raised fully. Does anyone know the proper rigging for this sort of reefing system? Help would be greatly appreciated! (I've disconnected the whole thing and hope I don't have to reef before I figure it out!!)Thanks!
