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 attached to masts. Sailboats can vary in size, from small dinghies to large yachts, and are often used for recreation, racing, or long-distance travel. Sailboats operate by adjusting the angle of the sails to catch the wind effectively. The design of the hull and the arrangement of the sails influence the boat's speed and maneuverability. Popular types of sailboats include catamarans, keelboats, and sloop rigs.
