    Typing this on my phone so I have to be brief. 

    The sheeting is a 6:1 on the main and 5:1 on the fore with a +2 on the topmost batten, even +/-1 on the other battens, and a 1/2 on the boom.  So it has anti-twist tendencies. No euphroes, just the sheetlets blocks.  It is similar to the original sheeting drawing by Benford for Badger, I am told. 

    I'll submit a drawing when I am back in my normal computer. Hopefully this gives you some info to work with.

    Daniel,

    Can you post your sail plan and sheeting digram please. It looks like you need an anti-twist sheeting system but from the photo's it appears you are using a non anti-twist system. Read PJR chapter 4 "The Sheets" and in particular look at figs 4.24 & 4.28.

    It would be interesting to see what sheeting setup you use. I suspect that it doesn’t have sufficient anti-twist in it. Could you draw it, scan it and put it among your photos?

    Another thing: I have found it easier to make a reefed sail set well if I depower the sail while reefing (I also do that when hoisting another panel). This lets me set up yard and luff parrel and thus ‘lock’ the setting of the sail before hauling in the sheet again.

    Ok my junkie friends, here's one that's got me fairly stumped at the moment.

    When my sails are full or nearly so, they take on a lovely twist off the wind that seems to make them nicely stable and ridiculously fast in light air.

    As soon as I pop a couple reefs in, though, the set goes all to hell and they get a nasty hook in the lower panels, with the top ones blowing off.  Here are some photos to give you the idea:

    The topping lifts are set up to hold the boom at the right angle when the sail is furled and they relatively closely match the angle of each batten within 5-10 degrees or so.  However, the sail is cut a bit too long for the mast (actually I think the mast is set a bit further in the boat than planned) so the boom is a bit too low when the whole sail is hoisted.  I can't recut the sail now (will do over the winter) so figured I would just try raising the lowest panel and lashing it to the boom for now, effectively tucking a permanent reef in upwards instead of downwards and allowing me to set the boom exactly in line with the batten angle.

    But that still doesn't explain the horrible "hook".  

    Can anyone help me figure this out?

    Thank you!
