And whatever you call it, I agree with PH-UKU about it being great fun. I only did half an hour, and I could easily have got completely hooked. If you like flying and you like sailing, this is a great combination of the two. If you like basic flying - no ATC, no windsock or other aids, reading the wind and the weather from the hills and the ripples on the water - this is for you. Maybe I should go back and do more!
