I got a good look at my friend's boat today. Its got daggerboards instead of centerboards. So he got an 18 instead of a 17.
We're looking for some sails in decent shape. "Serviceable" is an apt description (hell, my G-Cat's dacron sails are 20+ years old with a good number of patches, and still sail well enough for me.)
Preferably in the Tampa Bay area, and with battens.
It's got the roller furler for the jib, but no wings or otherwise specialized gear, so I don't think it's the SX version.
