Power Boats

Basically there are 2 hull types of powerboats Planing and Displacement. In the pictures

The planing hull allows the boat to rise quickly out of the water, allowing the boat to travel
at higher speeds.
The displacement hull does not ride up on top of the water; rather it pushes through the
water.

are two basic hull types of sailboats:
