Exactly! That's why I was drawn to this setup-
I have tried my old 17sqm Goodall kite tacked off a line between the bows (that's the one in the avatar) and it sort of works although the clew psoition is all off. I don't think this would work with the sloop but I'm specifically interested in the uni setup- I'm not crazy about the added weight/windage/rigging complexity/etc. of messing with the pole etc. and am trying to find an alternative. Just got my spi back from the sailmaker made expressly for this purpose but haven't had a chance to try it out yet. I have just been launching from a tramp bag but that's tough in any kind of wind by yourself IMO.
