Sailing boats are watercraft that use sails to harness the wind for movement. They come in various sizes and designs, from small dinghies to large yachts. The main components of a sailing boat include the hull, sails, mast, and rudder. Sailboats can be used for recreation, racing, or long-distance travel. These boats operate by adjusting the sails to catch the wind, allowing them to move forward. The direction and speed can be controlled by the sailor through techniques like tacking and jibing. Popular types of sailing boats include catamarans, sloops, and ketches.
