On Small-Size Motor Yachts with Round-Bilge Hulls
Victor A. Dubrovsky
Abstract
In this paper multi-hull small-sized motor yachts with rounded bilge hulls were examined as alternative options for enough high speed: catamarans without and with under-water foils, as well as outriggered boats without and with foils. Besides, a twin-hull motor yacht with decreased water-plane area was examined too. Restriction of speed, as a result of avoiding hard chine, was examined; necessary power and seakeeping levels of the examined yachts were estimated too. It
has shown that the examined yachts are compatible (from the energy point of view) with today’s dominant planing monohulls for defi ned ranges of speed; the examined multi-hulls are better from the seakeeping point of view than the comparable monohulls.
