On the Hull Shape of Full Ships with Low Speed

Abstract

Sharper bow waterline shape can reduce the wave added resistance at sea more than that for conventional blunt bow. Ax-Bow is an example based on such principle. The bow with sharp waterline at all waterline heights can reduce the resistance further, but the effect of the bulbous-bow is expected to become deteriorated. According to the model test results on a low speed full ship, such bow shape with all sharpen waterlines show the same performance in still water, and better performance in waves in comparison with a conventional blunt bow.
