We are talking about the 356? On mine both reef lines come out a pair of blocks that was part of the end plate of the boom. My boat was a roller reefing main, which in retrospect should have switched to slab reefing. Anyway, if you just tie the reef line from the boom end plate block to the leech reefing cringle it will pull the leech back but not down enough. You need the reeve the reef line through the cringle and then either tie it to the boom, or run it to an eye, directly below the cringle. That way when you tighten the reef line the sail will be pulled down and back. Getting the sail flat may be more important than getting the cringle to the boom. A well tied main reed is a beautiful thing. It reduces sail area, flattens the sail and lowers the center of effort for the sail plan. It may not be correct to say it reduces power since in higher wind the power is as much as a full sail in lighter air.
