A foilboard, also known as a hydrofoil board or foil surfboard, is a type of board used in water sports; it is distinct from surfboards in that it has a hydrofoil rather than fins mounted underneath.[1] This hydrofoil design allows the surfboard and its rider to rise above the water’s surface, allowing for fast speeds and increased maneuverability in a wide range of surf conditions.[2] Foilboards are becoming increasingly popular across many water sports, including surfing, kiteboarding, windsurfing,[3] and wakeboarding.[4] Foilboards have also been used in competitions, with riders reaching speeds of up to 30 km/h while performing acrobatic maneuvers such as flips and twists.[5]
