ABSTRACT:
Surf board has multiple functions to serve as the sail boat, surf board, wind surf board, canoe and the rest seat on water. It comprises a foldable revolving sail, water wings, single sided pedals, water turbine, water jet nozzle, the foldable reclining seat and board with removable canoe cover. The revolving sail drives the horizontal water turbine to generate the water jet. The water jet may swivel to propel the surf board in different direction. The revolving sail also serves as the sunshade umbrella. The foldable revolving sail adopts the flexible parafoil sail. If the wind is weak, the rider steps on the single sided pedals to rotate the water turbine to propel the board. Furthermore, the revolving sail and water wings lift the board to glide in the air and land softly.
