Planing

PLANING: A boat is said to be planing when it is essentially moving over the top of the water rather than through the water.
PLANING HULL: A type of hull shaped to glide easily across the water at high speed.

Planing Hulls--Planing hulls are designed to ride on top of the water, regardless of the weight of the boat. The flatter the bottom, the easier it is to get on plane. Also, less power is needed to attain high speeds with a flatter hull.

planing speed - The speed needed for a boat to begin planing.
planing - A boat rising slightly out of the water so that it is gliding over the water rather than plowing through it.

Planing
Descriptive of a hull that is designed to rise farther out of the water as boat speed increases. Such a hull is typically shaped like a V, as seen in cross-section from the front or rear.

planing hull - A hull specifically designed to reduce friction and increase speed.

Planing:
The Planing Hull form is configured to develop positive dynamic pressure so that its draft decreases with increasing speed.

plane, planing boat
Plane rhymes with "main". For a boat to skim across the water rather than plow through it. Planing boats (hulls) are lightweight and have relatively large engines or sails.

As usual, planing hull power boats suffer wind effects more than others, but I have also seen exactly this docking defeat moderately experienced skippers in displacement hull boats (even full-keeled sailboats).

(12" dia., 15" pitch, left hand rotation, 1" shaft) PLANING HULL A hull that lifts and skims the surface of the water causing the stern wake to break clean from the transom.

Accelerating and Planing
Acceleration tends to make a boat leave the water and hydroplane on the surface; this movement is triggered by the wash of the motor. It lifts the boat by several degrees.

The theoretical speed that a boat can travel without planing, based on the shape of its hull. This speed is 1.34 times the length of a boat at its waterline. Since most monohull sailboats cannot exceed their hull speed, longer boats are faster.

semi-displacement hullA hull shape with soft chines or a rounded bottom that enables the boat to achieve minimal planing characteristics. sheerLine of the deck or gunwale from bow to stern as viewed from outside the boat.

Planing hull boats ride on top of the water, climbing over their own bow wave created by a limited displacement capability.

The forward chine is all about designing a hull shape that will get up on a plane quickly The aft chine is all about stability and flat buttocks, again to help with planing speeds.
Chines will not work on just any boat.

The shape of a motor yacht's hull may be based on displacement, planing, or in between. Although monohulls have long been the standard in motor yachts, multihulls are gaining in popularity.

In addition, carrying the all-round light in the forward part of the boat closer to the sidelights minimizes the decrease in vertical separation (all-round light / sidelights) when the boat assumes a bow-high trim (e.g. in the case of a planing boat ...

Unless the boat is planing you need to try and keep the boat as level as possible fore and aft. As soon as the boat gets up on the plane you can move your body weight right back quickly so there is less wetted surface.

Displacement Speed:
The theoretical speed that a boat can travel without planing, based on the shape of its hull This speed is 1.34 times the length of a boat at its waterline. Also known as hull speed.

Helm: The boat's directional controls, tiller or wheel of a boat.
Hike: Leaning out over the side of the boat to counteract heel.
Hull: The body, or shell of a boat.
Hull Speed: The maximum speed a hull can achieve without planing.

Displacement hull boats have a maximum hull speed based on characteristics such as waterline length, draft, smoothness, etc. To overcome this limitation, planing hulls (speedboats) and hydrofoils rise out of the water at higher speeds.
