on many big spots kite and windsurfers are separated. In Leucate France there is a special kite area, on the entire Dutch shore there are specified kite and windsurf areas (not that there aren't any mixed ones). But the smaller spots can idd be dangerous and kitelines can be very annoying; i once had to drop everything in full plance because a kiter crashed his kite and i couldn't jibe away anymore. out of respect for the blokes gear i basicly endangered mine.
