Sorry I don't know the length of mine but too long is better than too short.When you are fully sheeted out for downwind,is there any line left in your hand?I would prefer there to be at least 5 or more feet to spare...Barry
Thanks for your answer Oliversdad. I wonder, when I m fully sheeted out if the boom should be close or touch to the shroud ? If yes, is there any chance to tear the sail on shroud speader ?
the boom should not touch the spreader, but the sail will... in time it will chafe thru the sail, but once you see the wear point (by the dark staining where it touches), you can reinforce it with a patch of sail tape BEFORE it wears very much and prevent any problems.
My mainsheet has a stopper knot tied in it to where the boom goes just short of the spreader for downwind work, and then I've got maybe 3-5 more feet after that. I figure just to make it easy to grab the sheet if I need to when the boom is all the way out, as opposed to digging the stopper knot out of the block. This is for my end boom sheeting, of course. Also, the boom is set a few inches shy of the shroud, just in case there's a crash gybe, I don't want the boom taking abuse from the shroud. Of course, with end boom sheeting affixed to the backstay, there might be a fair amount of stress all around for crash gybes.
Then again, for some racing dinghies in big wind, I've seen videos around the gybing mark, and every gybe is a crash gybe. And every time I shudder as the boom whips around and stops short, that the whole rig is gonna come down....
If your mainsheet is too short, such that the boom stops actually feet from the shroud, I think that's bad, because on a broad reach or run, I think there's a higher chance of inadvertent gybing.
