Sailing Boats are vessels being equipped with mast/s and sails. The primary advantage of these boats over motor boats is that they can cross seas and huge distances without refueling. Also, because Sailing Boats are mainly powered by wind through sails, they are more dependent on the weather conditions and brings a slower cruising velocity than motor boats. Their design is also restricted (hydrodynamics and aerodynamics). Sailing Boats usually have smaller dimensions in height and width and smaller volumes. Sailing Boats are often less equipped in their interior space than Motor Boats. But Sailing Boats are less sensitive to maritime conditions such as roll, pitch and yaw. Two major types not depending on the length of the boats are cruising boats and racing boats. navigating, mooring and powering sailing boats are more difficult than doing so with motor boats. Thus, the maritime law gives sailing boats priority over motor vessels. In some nations, ther is even a separation when licensing a skipper.
