"Windsurfing (... called boardsailing) is a sport involving travel over water on a small 2-4.7 meter board powered by wind acting on a single sail, that is connected to the board via a flexible joint. The sport is a hybrid between sailing and surfing. The sail board might be considered the most minimalistic version of the modern sailboat, with the major exception that steering is accomplished by tilting the mast and sail rather than with a rudder. Windsurfers can travel over flat water as long as there is enough wind; they can also cut into breaking waves and perform spectacular stunts. Windsurfing is very versatile by its relation to the sailor. It can mean a peaceful relaxed pastime on the water to some people, it can be a high-stress high-adrenalin sport to others, but it can also be a lifestyle of seeking the endless limits of perfection in skills and self-expression."
