About 5.45 last night I saw the aftermath of an alleged deliberate collision between a windsurfer with an orange sail and kiter with a purple kite at Dutch Inn, Cottesloe,. The allegation is the windsurfer - described as "big blond guy" - deliberately aimed for the kiter. I know the kiter, and he's a nice guy who knows the water rules, And I can believe there was an aggro windsurfer out there because I was warned twice about one before I even got my gear to the beach. The kite and board were interwined about 50m form the beach for some time. It was howling. It could have been a lot worse. What concerns me is others on the kitesurfing Facebook page reported having similar aggressive interactions with the blondie in the past, at Dutchies and The Pond. If you know him, please tell him to desist, or head the fark offshore to get his kicks. We are all not kids, kiters and windsurfers, and this is not place for surf nazi carry-on. Others will not have cool heads, and I'll punt eventually someone will be thumped, giving Cottesloe Council yet another reason to review both our sports' use of Dutchies. Please police your water brothers, if that's the case. Thanks, and good winds to you all.
