Schaefers' have a really good diagram in the back of the catalogue depicting single-line slab reefing. I am putting two such set-ups, one on either side of the boom, for two separate reef points.In brief it is a line dead-ended at the gooseneck, run up through the forward cringle, back to the after cringle, down to a cheek block on the boom and forward to a cleat on the side of the boom. Be sure to locate the cheek blocks so as to allow the reef line to pull at the right angle as an outhaul for the reefed sail (i.e., far enough aft).To reef, slack the halyard, take up on the reef line till the rest of the reefing eyes come down to the boom, and make the bundled sail fast before readjusting the halyard or downhaul. In theory it is the easiest way to go-- ideal for singlehanding.JC 2
