A piece of hull (1) of a boat, vessel or other construction designed to travel over water, which piece is attached with devices (6 and 7) to the rest of the hull (2) in a manner that allows the pieces of hull move relative to each other. The piece of hull (1) is located partly or in its entirety in the bow half of the hull combination (1 and 2) and comprises at least an engine (3), a power transmission mechanism (4) and a propeller (5) or an impeller. The piece of hull (1) according to the invention aims at mimimizing as many of the negative features of boats provided with an engine as possible, such as the noise and vibrations caused by the engine, power transmission mechanism and propeller, the shocks and violent movements caused by the action of the waves, the overturning effect of the headwind and the waves, frictional resistance, uncomfortable travelling position at low speeds, high threshold of planing, and poor steerability at low speeds. The invention has a minimizing effect on the negative features through its construction, location, and operation. The boat is steered either by means of a rudder (8) or by means of a steering device located in the piece of hull (1). The piece of hull (1) can be provided with trim planes. |
