One design sailboats are boats that are designed to be raced against other boats of the same design. They are usually used in fleet racing, where a group of boats of the same design compete against each other. One design boats are designed to be as equal as possible, so that the races are won by the sailors who are the most skilled, rather than by those who have the fastest boat. They are typically smaller boats, and are often used for training or recreational racing. Some examples of one design sailboats include the Laser, the Optimist, and the J/22.
