Oh yeah those things are cool! Their is a fleet of them that sails around here.
I don't know much about them, I have never sailed one. But they seem to have a pretty simple rig, almost like sailing an RC sloop. Supposidly they are good for training, one of the best sailors I know sails one on the off season.
I kind of stopped this summer, but this is what I usualy race:
If you are looking for a sailboat thats a bit more challanging and you want to learn how to
really race sail Star's.
