RESISTANCE OF CONVENTIONAL SHIP FORMS WITH LARGE BULBOUS BOWS. 1. SERIES 60, C SUB B EQUALS 0.60. 2. SERIES 60, C SUB B EQUALS 0.70

The resistance of conventional ship forms with large bulbous bows is reported, based on studies using two separate models and bulb designs. Test procedures and results are given for each series. It is concluded that the optimum configuration of bulbous bow should be specified from the first step of the hull design, instead of fitting a bulb to a convention hull form. Test results indicate that with a larger fillet behind the bulb, the residuary resistance is increased both in the full load and ballast condition.
