A Study on the Effect of Different Types of Bulbous Bow on Resistance of a Fishing Boat Using Maxsurf

Abstract

Bulbous bows are used to reduce the resistance of fishing boats. The aim of this study is to determine the type of bulb which will be more effective in reducing total resistance on fishing boats. In this study, a conventional fishing boat hull without bulbous bow is taken and its resistance is found using MAXSURF software at different Froude numbers. Delta (?), Nabla (?) and Elliptical (O) bulbs were added to the hull form and the corresponding resistance characteristics of each bulb was predicted. The results were compared to show the effect of bulbous bows on resistance of fishing boats.
