Hull

This section describes the different types of hull.

Displacement Hull

A ship with a displacement type hull moves by cutting through the water and pushing it aside. Boats with displacement hulls are limited to slower speeds. Most large boats, sailboats, cruises, canoes, catamarans etc., are made of displacement hulls. Round bottomed hull and multi-hull are some examples of displacement hull.

Planing hull

Boats or ships with planing hulls rise up and glide on top of the water rather than pushing it aside, when enough power is available. They are designed to work at higher speeds. The working is similar to a displacement hull at low speeds, while they rise up the and glide on the water surface as the speed increases. Power boats, small sailboats, personal war crafts (PWCs) are examples of vessels with planing hulls. Flat bottomed hull and V-bottomed hull are some examples of planing hull.
