Hydrofoil
surfboard is like a hydrofoil boat where there is a wing-like structure
underwater that, at speed, lifts the hull above water.The aluminium design is
affordable, robust and stable.
This
technology has entered the world of Stand Up Paddle boarding with the
hydrofoil. The foil insert into the fin box of the bottom of the board, and
once you hit a certain speed, either on a wave, from paddling, or once enough
wind gets trapped under your board, the foil will lift the board and the rider
above the water, providing the rider with a flying sensation.
