ABSTRACT

YTU Gulet Series with Cruiser Stern was produced from the original main of 21 gulets with cruiser stern as a result of iterative study. Some important relations and graphs are presented for use in the geometric design stage by determining significant design requirements and a geometric design process. Geometric design block coefficient (C_B0) was chosen as main parameter in determining the gulet hull forms. The method of form derivation was then developed related to C_B0. In this method, the change of the ratio of any station breadth at any waterline to breadth overall (B_i, _k / B_OA) according to C_B0 was exactly represented with a quadratic polynomial function. In addition, a computer program named “YKGH” was developed. With this program, a gulet hull form with cruiser stern can be derived for the desired number of cabins or the desired number of guests, L_OA, C_B0 and the keel breadth. At the end of the study, by using YKGH and AutoCAD programs, a gulet hull form was derived and her geometric and hydrostatic values, the offset values and form plans were presented.
