Meaning and Definition
A type of boat hull designed to ride on top of the water at speed, rather than through it.
A hull form that utilises hydrodynamic lift, generated by its shape and speed, to rise and skim across the water's surface, significantly reducing drag compared to a displacement hull.

FAQ
Frequently Asked Questions
A displacement hull pushes through the water, limited by its 'hull speed'. A planing hull uses power and shape to lift itself onto the water's surface, skimming over it, allowing for much higher speeds.
Some high-performance sailing dinghies and catamarans are designed with planing hulls to achieve very high speeds. Most traditional cruising sailboats have displacement hulls.
It requires significantly more power (and thus often more fuel) to get 'on the plane' and maintain that high-speed, lifted position compared to a displacement hull moving at its lower natural speed.
Yes, conceptually. Both involve using a shaped surface moving at speed to generate lift—one in air, the other in water.

Learning
Memory Aids
Mnemonic
Think of a 'planing' hull like a 'plane' (aeroplane): at speed, it lifts up to 'fly' over the water, not plow through it.
Conceptual Metaphor
SPEED IS FLIGHT; WATER IS A SURFACE TO SKIM.
