Battery Power Rating - What does âAh' mean? Finding the correct battery size for your requirement can prove difficult, with terminology appearing somewhat confusing.

On the other hand a planing hull is like the wing of an airplane and as speed increases, it creates lift and rides on top of the water, just like your flat hand lifts in the wind. A good example is a regular surfboard.
On many vessels, these projections from the main body of the vessel can be attached and removed quickly and fairly easily. On airplanes designed to take off or land in water, a sponson can help extend the hull higher in the water to aid in lift when the plane is taking off. This prevents the plane from sinking too deeply into the water, creating more drag.
