Sailboats are small boats using wind on their sails to give the desired direction to the boat. Keelboats, yachts, trimarans, skiffs and catamarans are all the types of such boats only. They are generally used for day sailing, cruising and racing. Sailboat-racing is a very enjoyable sport and can be had in any such boat. Most of these boats are built of fiberglass but aluminium or steel are a better choice if strength is a consideration.
