Generally speaking there are two types of boat hulls. They are the displacement hull and the planning hull. The hull type will play a significant role in the purpose of the boat and how and for what it is used. When deciding to own a boat, understanding the differences in these two hull types will ensure, at the least, the boats design will be capable of fulfilling the purpose for which you intend to use it.
Displacement Hulls:
The displacement hull derives its name from the fact that when the boat is placed into the water it pushes aside or displaces an equal amount of water. The weight of the water that is displaced is exactly equal to the weight of the boat.
This type of hull has a round bottom which makes it subject to rolling from side to side. This is particularly true when the sea conditions become rough. To offset this condition some form of stabilizers will generally be deployed thus smoothing out the ride.
When moving forward this hull type must push aside the water as it maintains its full displacement whether moving or sitting still. The hull will never rise above or onto the surface of the water.
Every boat has a maximum hull speed. It is calculated using a complex formula which takes into consideration the boats length. The longer the length of the boat the greater its hull speed will be. A displacement hull will never exceed its hull speed regardless of how much power its engine has.
Since increasing the power does not increase the speed displacement hulls are usually powered by small engines and cruise at speeds in the neighborhood of eight to twelve knots. This of course varies depending on the size of the boat and its particular design characteristics.
Planing Hulls:
Planing hulls will also push aside or displace an amount of water equal to their weight when they are at rest in the water. However, they are designed to rise up out of the water and ride on the surface when they reach a certain speed. This planing speed varies from boat to boat depending on the particular hull design.
The three main types of planing hulls are: the Flat Bottom, the Vee Bottom and the Deep Vee Bottom. The flat bottom boat is a planing hull but it produces such a rough, pounding ride it is seldom used for anything much larger than a dingy or boat tender.
The vee bottom and deep vee bottom produce the softest ride on the water. The deeper the vee the softer the ride will be. However, the deep vee hull requires more power to get it up or planing than does a normal vee hull.
Planing hulls like displacement hulls also have a calculated maximum hull speed. Because the design of the planing hull allows it to break free of the water and ride on the surface it is able to exceed its maximum hull speed. Thus, generally speaking the greater the power of the engine the faster the boat will go.
Whether the boaters desire is to travel at a leisurely pace or to get from point A to point B as fast as they can there is a hull style that will accommodate them. When purchasing a boat it is important to know which type of boater you desire to be and what is the main purpose for which the boat will be used. Knowing this the correct type of boat hull will be selected.
