These boats are generally less expensive to build and have a shallow draft.

A monohull boat is the typical design that most people imagine when thinking of a boat. The single-hull boat is called a monohull while boats with two hulls are known as catamarans and three-hulled or tri-hulled boats are known as a trimaran.

The monohull fast sealift MFS hull or semi-planing monohull SPMH design is the hull form which is widely used today in smaller semi-planing ships because it offers the possibility of using waterline lengths approaching that of displacement hulls and maximum speeds approaching that of planing hulls. They can get up on plane easily but unless the water surface is perfectly calm they tend to give a rough ride because of the flat bottom pounding on each wave. Monohulls may have full keels bolted on fin keels or a swing keel.

Monohulls as the name implies have one hull. The monohull or the multi-hull. 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.

There are four common types of boat hulls. Board-up keels allow the boat to travel on shallow water. The monohull or single-hull boat is perhaps the most common boat design in use today.

Because the boat is not as susceptible to the effects of wave action and does not heal the way a monohull does it is much easier to walk around on deck and within the interior of the yacht while underway. This makes production a lot more expensive. Monohulls are more budget-friendly especially as there are lots of very good solid small sailboats from the 70s 80s and 90s that can be bought for dirt cheap.
