Motor boats usually have two types of hulls: displacement or planing.
The displacement hull is associated with slower boats which are longer in length and which need great stability for long-distance sails.
The planing hull combines a lighter weight, relatively more power and lift to slide over the surface of the water, which gives the boat more speed and agility but less resistance.
In the recreational boat category, the most common motors are usually inboard or outboard.
Inboard engines are located at the stern, and can work in various ways: through the transom by the means of a Z-shaped tail; through a fixed axis which passes through the bottom of the hull; or directly connected to pod drives which include the transmission, tail and accessories located beneath the hull.
Outboard engines are installed on top part of the transom and have a propeller and a steering system. There are two types of outboard engines: the two-stroke, lighter and easier to install, but also causes more pollution; and thr four-stroke, quieter and more environmentally friendly, but also heavier and expensive.
Today there are also several electric propulsion and hybrid solutions which are more environmentally friendly and which are becoming increasingly efficient.
