A 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,B-k/B-OA) according to C-B0 was exactly represented with a quadratic polynomial function. In addition, a computer program named CGCS 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 CGCS and AutoCAD programs, a gulet hull form was derived and some geometric and hydrostatic values, the offset values and form plans were presented.
