A sailboat is a type of watercraft that uses sails to harness the wind for propulsion. It typically consists of a hull, which is the main body of the boat, and one or more sails that catch the wind. Sailboats can vary in size, from small dinghies to larger yachts, and are often used for recreation, racing, or travel. Sailboats are steered using a rudder and can be equipped with various features, such as a mast to support the sails and keels or centerboards for stability. They are popular among sailing enthusiasts and are often seen on lakes, rivers, and oceans.
