Title:
SHIP HULL STRUCTURE COMPRISING WAVE RESISTANCE INCREASE MINIMIZING STEPS
Document Type and Number:
WIPO Patent Application WO/2011/105079
Kind Code:
A1
Abstract:
Disclosed is a ship hull structure comprising wave resistance increase minimizing steps, which minimize increases in wave resistance without increasing resistance in calm water. The hull structure comprises bolsters (20) for anchors, which are disposed upon the bow (11) of a vessel (10), and wave resistance increase minimizing steps (30) that repel waves. The wave resistance increase minimizing steps (30) are disposed below the bolsters (20) and above a still water level elevation location (A) upon the bow (11), and minimize resistance increases in waves from the bolsters (20).
