HULL TYPES

There are four common types of boat hulls.


FLAT-BOTTOMED HULLS

Boats with “flat-bottomed” hulls are very stable, great for fishing and other uses on calm, small bodies of water.


ROUND-BOTTOMED HULLS

“Round-bottomed” hulls are typically displacement hulls, and are designed to move smoothly through the water with little effort. An example of a round-bottomed hull is that found on a canoe. One drawback to the round-bottomed design is that it’s less stable in the water and can capsize more easily. So, extra care needs to be taken when entering, exiting and loading these types of boats.


V-SHAPED HULLS

“V-shaped” hulls are planning hulls, and are the most common type of hull for powerboats. Deep v-shaped boats are designed to plane on top of the water at higher speeds and provide a smoother ride through choppy water. These boats are usually equipped with a larger engine than flat or round-bottomed boats.


MULTI-HULLED

Finally, let’s look at “multi-hulled” boats. These boats can have either planing or displacement hulls depending on the shape of hull and size of engine. Multi-hulled boats are some of the most stable on the water. They also require more room to steer and turn. Examples of common multi-hulled boats are catamaranstype of multi-hulled boat or ship consisting of two hulls that are joined by a frame. and pontoon boatstype of motorized multi-hulled boat consisting of two hulls joined by a frame..
