They are designed with a special shape called an airfoil, which encourages passing air to turn and deflect downward. This is why the typical airfoil shape has a curved top and a flat bottom, especially in slower-speed general aviation aircraft. Newtons Third Law tells us that we need to push air downward to produce an upward force.

Combining the Gweduck’s advanced hull with its counter-rotating propellers means differential power allows crosswind water taxiing impossible in floatplanes along with higher hull-in-water taxiing speeds. “We Another advantage of the counter-rotating props is the elimination of torque roll. A not so obvious advantage is taxiing.
