The Boat

Hull Types and Design

Hull types: displacement vs planing, with deep-V, flat-bottom, and modified-V cross-sections

Hull design determines how a boat performs in different water conditions.

Displacement hulls move through the water, pushing it aside. They're efficient at slow speeds but can't plane. Sailboats and large cruisers typically have displacement hulls.
