ABSTRACT:
The invention is a monohull water-borne craft comprising a hull having a main portion and an opposed pair of stabilizers, the stabilizers being positioned on opposite sides of the main hull portion and being disposed closely adjacent to the main hull portion. The stabilizers may be elongate and arranged with their long axes extending along the main hull portion to form pods. The stabilizers may be integral with the main hull portion or may be movable, e.g. to enable variable geometry to give active buoyancy and/or ballast and/or assistance in steering or stability. The stabilizers may carry propulsion means, fuel tanks, active ballast tanks or the like. The stabilizers may thus be single function e.g. to provide buoyancy, ballast or to house equipment such as propulsion means or may be multifunctional to combine one or more of such functions. The craft may be a power boat or a sail craft and may be convertible between power and sail. The stabilizers may be housed, at least partly, within cavities in the main hull portion.
