Step

 

a break on the bottom of a high-speed boat; when the boat is in motion, the step creates a lifting force that causes the boat to rise and glide over the water’s surface. When a boat is hydroplaning over calm water, that is, when it has risen onto its step, less of its bottom is in contact with the water and, as a result, the water offers less resistance to the vessel’s motion. There may be one or more steps on the bottom of a hydroplane, cutter, scooter, or the float of a seaplane. The shape of the step (flat, flat-keeled) determines the vessel’s seaworthiness and speed.
