| Abstract: | A method for evaluating the resistance of high speed round bilge hulls in shallow water is presented, based on model test series and regression analysis. The shallow water resistance calculation formulas given in this paper are expressed for sub-critical and super-critical speed regions, and a formula for discriminating sub-or super-critical speed is given.These formulas may be used for speeds up to Fr =0.8. In order to examine their accuracy,two full scale crafts trials were conducted. A comparison between the test data and calculated results shows that the agreement is satisfactory. Furthermore, estimation charts are made for practical use. |
