Hull Types and Uses
There are two types ofdesigns: planing and displacement.
- Planing Hull – is designed to lift and ride on top of the water as it gains speed. Most small power boats have a planing hull design.
- Displacement Hull – is designed to travel through the water. and large cruise ships use displacement hulls because their size and power will not allow them to plane.
There are four basic hull shapes found on recreational watercraft:
Flat Bottom – Found on fishing boats. They are best in calm, shallow waters.
Round Bottom – Found on canoes. These boats glide slowly through the water with little effort. They do roll easily, so use caution when entering, exiting, loading or unloading the boat.
Deep-V Hull – Found on powerboats. These boats move smoothly through rough water at high speeds. They generally have a larger engine.
Multi-hull – Found on catamarans and pontoon boats. These boats are very stable but have a wide turning and steering radius.
