Air energy captor for sailing vessel - comprises stiffened curved triangular sail which holds wind to provide energy supplement

摘要

A square section mast has a curved triangular sail stiffened by the rear face of the mast. The sail is hollowed by stiffening and two running clips to give a light convexity. One clip is at one quarter, and the other at three quarters of the sail height. This positioning enables the sail to hold the wind. When there is no wind to propel the boat, the wind held in the sail provides a wind energy supplement. ADVANTAGE - Enables boat propulsion when wind drops.
