Mark,

I did wonder if that picture would appear....


I agree that the GP sails kite is quicker. When Grant and I were talking about building it we decided that flat would be faster overall (but harder to trim consistantly, but we decided that the trade-off was worth it). I'm still learning how it works properly and I think it will be very halyard tension critical. Too little in big winds and it does not set, too much in light stuff and the leach twists away and the luff will not set at all.

I'm still fiddling with Battens in my GP mainsail. More info when I have worked it out but so far I am sailing with a lot ofd tension in the top 4 battens to support the leach as the downhaul comes on.
