Topic-icon Fabric for snuffable jib...

I've been flying a jib on my Triak for a few years now. Unfortunately, dacron polyester is too stiff to snuff because 4 ounce dacron would probably be perfect. I've been experimenting with different fabrics but haven't found anything satisfactory. I've used tarp and it was too stretchy, I've tried various polyester fabrics but all seem to be too stretchy. I've tried nylons but they were WAY too stretchy. My next attempt will be ripstop polyester for high performance kites. But it is so lightweight I think it'll deform in a decent breeze (but I'm making it for a windseeker to use in winter so that'll be OK then). I haven't tried code zero fabric even though I have some because 1) it isn't blue and I like my sails to match and 2) I don't think it will survive being snuffed (Mylar and taffeta and kevlar strings).

I may be the only person who wants a snuffing jib, but I sure could use an idea about what might work. Thanks.

SO far, so good. The polyester kite fabric is extremely dimensionally stable, no stretch at all. I've flown it in light breeze so far and works well. Will report back when I've tried it in bigger breeze. It snuffs like a champ.

The polyester kite fabric isn't suitable in big breeze. AND, if you do fly it in big breeze it will permanently deform...as I found out. SO, it is good for winter wind seeker material (but so is nylon for that use). I've made a jib from surlast polyester (sort of a light weight sunbrella). It isn't as firm as I'd like but it does snuff well. I've used it now in big wind (15-20 kt) and it performs OK...a bit stretchier than I would like; but sometimes you just have to use what comes to hand. The Triak isn't faster with a jib, nor does it point better--BUT, it does balance the boat so it tracks without using so much rudder. I'll keep looking for that elusive perfect snuffable cloth. Next thing I try will probably be another dacron but I'll make it smaller since all I'm using it for is to balance the boat and tacking.
