Windsurfing is a surface water sport that combines elements of surfing and sailing. It became popular in the 20th century after N. Darby introduced the idea of using a handheld sail, or sailboard, in 1948. The sport uses a board between 2 to 3 meters long made of foam or wood along with a mast, boom, and sail ranging between 2.5 to 12 square meters. Windsurfing involves using wind conditions, wave strength, and maneuvering techniques to control the board while sailing. Some of the top locations for windsurfing include Lake Arenal in Costa Rica, Tarifa in Spain, Maui in Hawaii, and Paros Island in Greece.
