Twisting mainsheet

[Bob Gauvreau]

We took delivery on a 36 mkII on July 8th (#1929). Love everything about the boat...except she has one idiosyncracy that we have been unable to solve. The mainsheet twists around itself at the point just below were it attaches to the aft connection on the boom.At the boom connection, there is a block that that turns. Theorhetically, the block should prevent the twisting of the sheet around itself, but it is the line that is becoming twisted (somehow) and so the block can't do it's duty.This is becoming a real problem, especially on jibes, when the line as 4-6 twists in it, seriously impeding rapid movement of the boom.Has anyone else encountered this situation? It surely cannot be unique to us. Suggestions/help/advice will be greatly appreciated.BobC-36 mkII / 1929 / "Purrrfect"

There should be a small set screw you can tighten to prevent this from twisting.

Soak mainsheet

The mainsheet might have developed a memory for the twist. You might want to remove the mainsheet and soak it in fresh water to remove the kinks.

I have the same thing but with only 1 twist

I have hull # 1800 and I have the same thing but it only twists once (180 degrees from ideal). I have just lived with it as it doesn't seem to impede anything in effectiveness. But if I had 4 or 6 twists I would probably pull the sheet completely out, spray the sheet with fresh water (maybe some fabric softener) and try and rethread the sheet thru the blocks , being very careful to keep the "lay" of the sheet consistent (re: not-twisted).Let me know if that helps.

The Blocks Shouldn't Twist

Andy's right, the blocks shouldn't twist and the set screws can be set to prevent them from twisting. This should solve the problem along with the other suggestions that comment on removing the set-in twist.
