Determination of Transverse Stability Properties of Yachts between 20 and 60 m in Length during Concept Design Stage by Employing Residual Stability Method

Consistent determination of unknown values ​​based on statistical data at the concept design stage is a widely used approach. It is clear that the determination of the main dimensions and capacities of the ships in the conceptual design phase at an acceptable accuracy is decisive for the success of the next stages of the design as well as the bid preparation. For yachts, the main dimensions, areas and volumes of the decks forming the top building besides the main values ​​such as ship size, width and depth directly affect the external design features and cost levels of such special boats.In the concept design phase, for example in the modeling of a characteristic such as stability, the minimization of the design variables to be used as much as possible gives the naval architect the ease of operation and the ability to control these variables more freely.In summary, it is aimed to present a simple and useful approach to the naval architect, which can be used during the conceptual design stage of mega yachts and yield an error level as low as possible. The resulting formula obtained from the method developed in this paper is given as follows:For Φ ≤ 30o: CRS . 103=       For Φ > 30o: CRS . 103=
