 Advancements in materials and hydrofoil design have created stronger rigs, gentler rides (shock absorbers in the seat), more maneuverability, and boards that combine sit-down and stand-up (air board) for surfing.Unlike water skiing or wakeboarding, a hydrofoiler's body and the board rise above the water, supported by a pair of front and rear hydrofoil wings which are still under the water.This reduces the drag of the water, allowing for both a smoother ride on rough water and a lesser need for strength.
