i have a 4m radsails pro by eolo from spain & a viokite vr8-6 from japan. it's an 8m water relaunchable closed cell foil that can be "zipped down" to a 6m by cinching in fabric in the middle for really high winds.

this is my first full year, really - & i hope to get a bigger better rig in a year or so. (something w/ a higher aspect ratio & of course bigger sail)
