GLIDING SHIP HULL Russian patent published in 1994 - IPC

FIELD: shipbuilding. SUBSTANCE: hull has bow section 1 in the form of curved triangular element corresponding to the hull outline (such as along the generating line in the form of a hyperbola) defined by split stempost and deck level. The hull has bottom 3 provided with central foil 6 and side sponsons 7, and a transom 2. The center of gravity and center of volume of the hull rest in a lateral plane dividing wettable surface of the hull into two equal parts. Foil 6 has a relative elongation of at least 70 at a length amounting to at least one third of the hull length to project away from the hull in the area of transom 2 and adjoin with a clearance to deadwood of suspension motor. Lower surface of the foil 6 is crimped upwards toward bow to at least 1% of the foil length. Side edges of foil 6 and bilges 5 have rounded surfaces of a radius not exceeding 1 mm. EFFECT: greater convenience in use, expanded functional capabilities. 2 cl, 3 dwg
