Our boat consists of the body of the boat, the propeller and the sail. It has a broader base for stability and preventing it from capsizing. It travels on the surface of the water and is extremely buoyant so that we are able to reduce the effect of water resistance. The motor and propeller are elevated as we want it to face the sail and make the impression that it is actually blowing the sail. The propeller is actually blowing backwards instead of at the sail, hence propelling the boat forward. Therefore, the sail is more of a decorative item which allows us to form an impression of blowing our own sail.
