Abstract
A vessel (30) comprising a hull (15) having an apparent centre of pitch (23) located at a position between about 10% and 35% of the length of the vessel (10) measured from the aftermost point (17) of the vessel on the design waterline. The hull (15) may be bare, or alternatively may be fitted with a damping system (31) located forwardly to provide damping forces to reduce the vertical motion at the bow and hence the vertical accelerations. In one arrangement, the vessel (10) may comprise a single hull vessel. In another arrangement, the vessel (10) may comprise a multi-hulled vessel.

A vessel comprising a hull with an apparent centre of pitch located at a position between about 10% and 35% of the length of the vessel measured from the aftermost point of the vessel on the design waterline.
A vessel comprising a hull with an apparent centre of pitch located at a position between about 10% and 30% of the length of the vessel measured from the aftermost point of the vessel on the design waterline when the underwater hull shape is bare and devoid of any hydrodynamic force generators such as foils or fins, and without the assistance of any external force generators such as gyroscopic stabilisers.
A vessel comprising a hull with an apparent centre of pitch located at a position between about 10% and 35% of the length of the vessel measured from the aftermost point of the vessel on the design waterline, the hull being fitted with a damping system located forwardly to provide damping forces to reduce the vertical motion at the bow and hence the vertical accelerations.
