I'm curious why only one of the plastic sheaves at the front of the boom is being used. Is the other one for a reefing line or...???
What is the second metal sheave used for at the aft end of the boom? The PO had the topping lift tied to it. Don't see why a sheave would be tied to...
The starboard side of my boom has an exit hole and cleat for the outhaul. The port side has an unused exit hole and a cheek block on a track at the rear. I was using the cheek block for reefing - is there supposed to be reefing lines inside the boom as well?
In the manuals and Brochures section of this website you should find a lot of the original manufacturer's drawings. This should answer a lot of your questions. Look in the selected architectural drawings for the boom assembly (page 4)
Well LT, This was a one design class, and while I do know they made changes during the production run, some things should have been relatively constant. The boom set up may not have been covered in the one design specifications. My boat is 433 built in 1985. I guess you need to find someone with another 1980 model boat to discuss this with. To try and answer some of your questions. My boat does use one of the aft end boom sheaves for the reef line. The other I've never used. The PO had run the outhaul down the mast and back to a block and tackle on the cabin top. I found this arrangement too cumbersome even though it allowed for a greater mechanical advantage than the in-boom system. I think he sailed more in higher winds and needed to crank the outhaul really hard on. If I had to venture a guess, I'd say that one of those outlets on the side of the boom could have been used for pulling the clew of the main down in a reef, but my boat was never set up for that best I can tell. Hope this helps. Good luck!
LT, that's an interesting set up. My boom is rigged like the drawings from Catalina. I only use one reef so I have an extra sheave because of that. They were the white plastic ones. I replaced with the black ones from Catalina direct. The reef line runs inside the boom. My outhaul sheave aft fell part a few years ago and that was also replaced with a new black plastic one from Catalina direct.
