I windsurfed for about 12 years. You are constantly buying new equipment, breaking things, breaking your body, the girls in minimal bikinis are nowhere around a windy beach. You are absolutly exhausted and have to unpack the car and wash down the gear. You have to go out a number of times a week to keep your sailing fitness up. I only liked big wave sailing but had to sail back and forth accross the *** harbour to keep my skills up waiting for big wave days. Kite sailing isn't much different
