Wing foiling or wing surfing or winging is a wind propelled water sport that developed from kitesurfing, windsurfing and surfing.[1][2] The sailor, standing on a board, holds directly onto a wing. It generates both upward force and horizontal force which can be used for propulsion and thus moves the board across the water. The recent development of foilboards, which plane very early on a hydrofoil fin and thereby lift off the water producing low friction, represent the ideal complementary hydrodynamic platform for wings.[3]
