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 sideways 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]
