Abstract

1300666 Hull form NIPPON KOKAN KK 29 April 1970 [16 May 1969] 20573/70 Heading B7A In a full form ship hull having a block coefficient of 0À75 or more and a length of 120 metres or more between perpendiculars:- (1) the bluntness Yf (as defined in the Specification) of the portion of the fore edge of the stem in the region of the fully loaded water line lies within the limits B/45#Y/f#B/15 where B is the maximum moulded breadth of the hull, (2) said portion of the fore edge of the stem extends perpendicularly below the fully loaded water line at the fore edge of the stem by at least 15% of the fully loaded draft with the same bluntness, (3) below said portion of the fore edge a protruding portion extends forwards for a distance I where 0À02Lpp#l#0À04Lpp, (4) the bluntness (Yb) of the fore edge of that part of the protruding portion more than l/3 ahead of the perpendicular portion is constant and 0<Yb#Yf/3.
