👉 Sails are a type of sail that can be used to propel an object. They are typically made from lightweight materials like nylon, polyester, or cotton and have a flexible structure that allows them to move in all directions.
Sails can also be used as anchors, which help to stabilize objects while they are being lifted or lowered. They are often used for fishing, sailing, and other水上活动,如划船、帆船和滑板。
