Types Of Hulls

Flat bottom boat – These boats are generally less expensive to build and have a shallow draft (the part of the boat that’s under the water). They can get up on plane easily but unless the water is very calm they tend to give a rough ride because of the flat bottom pounding on each wave. They also tend to be less stable and require careful balancing of cargo and crew. Examples of flat bottom boats might be Jon boats, small utility boats, and some high speed runabouts.


Vee bottom boat – The vee bottom tends to have a sharper entry into the water which provides for a smoother ride in rough water. They do, however, require more power to achieve the same speed. Many runabouts use the vee-bottom design.




Round bottom boat – These move easily through the water, especially at slow speeds. They do, however, tend to roll unless they are outfitted with a deep keel or stabilizers. Many trawlers, canoes and sailboats have round bottoms.




Multi-hull boat – Catamarans, trimarans, pontoon boats and some house boats use a  multi-hull design. The wide stance provides greater stability. Each of the hulls may carry any of the above bottom designs.
