Well, I'd been told that relations were tight sometime between kiters and windsurfers, but I didn't noticed it on this beach. Many of the kiters have been windsurfing there in the past so they understand how we sail. Anyway they tend to stay in shallow water so you need only a few tacks to get rid of the fleet.
And to be fair there were always a few crazy bastards who go straight or jump without taking care of others, whether on a windsurf or a kite. Hopefully they will move to scrabble with age.
