Application of Rankine source method for improving hull form of fishing vessels

Abstract

The Rankine source method is applied for improving the hull form of a fisheries research vessel. The vessel should be enlarged lengthwise. Furthermore, a bulge and a bulbous bow will be added. Effects due to these modifications on the wave making resistance are highlighted. The bulge decreases hull resistance and the physical reason is discussed. The method of optimizing bulge form is proposed and finally an improved hull form with optimized bulge is offered.
