Modeling and Comparison of Bodrum Gulets’ Hull Forms with Round and Transom Sterns

Gulets built-in Bodrum region, known as Bodrum gulets, are special and unique yachts with a rich historical background and aesthetic designs. Besides aesthetics, the engineered design is important for such leisure crafts; thus, hull characteristics should be analyzed using a binary approach. In this paper, the hull form characteristics of Bodrum gulets with round and transom sterns are investigated, and parametric models based on geometrical dimensions are developed. In order to obtain reliable results, 20 round stern and 24 transom stern Bodrum gulets are used for the parametric evaluation. Hydrostatic parameters of these models are calculated, and general characteristics such as beaminess and fullness are obtained. Additionally, the Holtrop-Mennen method is also used to estimate the resistance performances of these displacement type hulls. The distinctive or similar characteristics of these types of yachts are presented and compared. Finally, a parametric framework is developed for use in the preliminary design stage of such yachts.
