A Consideration on Design of Wave-less Transom Stern Form

Abstract

Some methods to reduce resistance due to transom sterns have been put into practice. However, the method to eliminate the resistance completely has not been clarified. In this paper, how to design wave-less transom stern form has been investigated based on the results of the authors' studies until now. To verify the clarified design method, model tests have been conducted. Results of the model tests have confirmed: 1) Almost no stern waves are seen behind the designed transom stern at Fr = 0.18 – 0.30. 2) Its resistance is clearly lower than those of conventional transom sterns at the Fr range.
