Hydroplaning and hydroplane have several meanings:

• With boats, planing or hydroplaning is a method by which a hull skims over the surface of the water, rather than plowing through it.
• With rubber wheeled vehicles, aquaplaning, planing or hydroplaning is a cause of loss of steering control when a layer of water prevents direct contact between the tires and the road surface.

• Hydroplane often refers to a specific type of fast motorized boat.
• Hydroplane sometimes refers to any watercraft that is specially designed to plane, for example a hydrofoil.
• Hydroplane sometimes refers to a seaplane, an aircraft that can land on water.
• Hydroplane is also a technical term for a submarine wing used to help control depth, analogous to the elevators on the tail of an aircraft.
