👉 The sail fluid refers to the material used to construct the sails of ships, boats, and other watercraft, typically made from natural fibers like cotton, hemp, or synthetic materials such as polyester. These fibers are woven into a fabric that captures the wind's energy, allowing vessels to harness it for propulsion. The sail fluid's design and tension are critical factors in optimizing the sail's performance, enabling efficient movement through water by converting wind power into forward motion.
