On the starboard side, aft end of the boom on our C-22, a previous owner added about a 30" track that has two adjustable blocks on it. There is also a cleat at the very aft end of the boom just above this track and no cleat forward. I assume this is for some kind of reefing system but I haven't figured it out yet. The port side of the boom has a cheek block aft, eyestrap mid boom, and cleat forward, that would seem to be the "standard" setup for reefing. There is only one reef point in the main and no flattening reef. There is also a reefing tack hook installed. I would appreciate any help, links, diagrams, etc. to point me in the right direction with this track and block thing. The attached "related link" shows a diagram of something similar and would make sense for our boat if there were two reef points and a forward cleat. Also, without a topping lift or boomkicker, what's the best way to support the boom when reefing? This boat has a split backstay and no pigtail, but does have a snap shackle in the crotch of the "Y" in the backstay. It is convenient for holding the boom while at rest and with the backstay loose, but it seems like it would be tricky to clip-in under reefing conditions. Any thoughts? Thanks John
