Both of them are sports. Although both of them are played outside, rugby it’s played on a pitch, while windsurfing is a watersport. In order to practice it you need an inexpensive equipment (ball, boots), compared to windsurfing whose equipment it’s an expensive one (sail, board, wetsuit). While rugby it’s a dangerous and violent sport, windsurfing is relatively safe and relaxing. You have to be strong enough to practice both of them because as a rugby player you have to be poeerful and fit as well as a windsurfer has to be not only a strong swimmer but also fit.
