The invention relates to boat building and can be used in the building and modification of sea-going high-speed keeled monohull sailboats or sail and motor boats with a high sail power to weight ratio, where a single, narrow, wave-penetrating displacement hull is used. To provide for the stable controlled movement of a keeled monohull sailboat or sail and motor boat in wave penetration mode, i.e. in a low wave/hydrodynamic resistance displacement mode, both when heeling and when upright (at the same time effectively counteracting heeling and rocking on all courses), and to provide for the damping of the energy of a broken wave and also for the ability of the boat to self-right to an even keel from a “sail-on-water” position, a stabilized hull for a keeled monohull sailboat or sail and motor boat is configured with an overall width of not more than 50% of the length of the hull and has, in the bottom part thereof, a vertically oriented narrow section (4) of low wave/hydrodynamic resistance, which runs longitudinally along the full length of the boat, is symmetrical about the centreline thereof and has a displacement segment (5) comprising a keel (8) with a heavy bulb, wherein the displacement of the segment is equal to the full unladen weight of the boat. The hull further comprises two narrow longitudinally oriented sponsons (6 and 7), arranged symmetrically in relation to the centreline of the boat, which do not bear the weight of the boat and which have a streamlined shape of low wave/hydrodynamic resistance. Said sponsons are situated above the waterline at the maximum width of the hull, forming two tunnel cavities (10) above the waterline to dampen the energy of a wave broken by the bow and the sponsons.

A trimaran which includes a self-righting structure positioned near the stern that substantially raises the center of buoyancy. The trimarans two peripheral hulls are shorter than the main hull and positioned near the one end to create an unstable inverted environment wherein when inverted the vessel rests primarily on the self-righting structure and an end of the main hull, substantially raising the center of gravity and creating an unstable configuration. This causes a pitch or roll about the vessel's longitudinal axis, which continues until the vessel has returned to its more stable upright position resting on three hulls.

A stability controller includes a machine learning engine that outputs stability settings to several on-board stability systems of a vessel based on various inputs. The machine learning engine is first trained based on human selections of stability system settings, and then, once suitably trained, the stability controller can be used to optimize the use and operation of the stability systems as conditions change, based on a quantity or stability quality that the vessel operator desires to optimize.
