Adam my son co-erced me into trying out his GPS, so here I am.  I just love windsurfing but don't think I'm very good as it has taken me years and years and I still can't do a decent gybe.  I can't even swim very well, but that doesn't matter as long as you can go fast and waterstart.  So, maybe I'll get in a few windy sessions this autumn and clock up some faster speeds.
