A sail propels the boat that derives power from the wind and helps the sailboat to move. It is supported by a mast made of metal or composite material attached to the sailing craft and is controlled by ropes attached to the boat. Sails were traditionally made of flax and cotton canvas but now are usually made of nylon, Kevlar or other liquid crystal polymer fibers. *We crave for more modifications and accuracy.
