ABSTRACT

Yacht design is a process that includes different disciplines such as naval architecture, design and interior architecture. The dynamic and challenging marine environment that surrounds the yachts requires many engineering calculations to ensure the safety of life and property. On the other hand, increased importance of concepts of aesthetics and personalization, the need for design and interior architecture disciplines in the yacht design process increases. Partitioning the hull, during the preliminary design phase guides the progressive design processes in yacht design. For this reason, knowing how much of a limited area of the hull should be reserved for the engine room, which is a critical part of the boat's cruise and safety, will facilitate the design processes. In this research, the engine room areas of different boat types were examined, and 72 yachts were investigated. As a result, the ratio of the length of engine room to the hull length of the yachts, the starting and ending points of the engine room over the length of the hull of a yacht were obtained depending on the boat type. The results reveal that the investigated vessels show a logarithmic distribution inversely proportional to their full length. The results reveal that the percentage of the engine room occupied by the hull has a logarithmic distribution inversely proportional to the full length of the boats studied. Moreover, the area occupied by the engine room on the hull compared to the full length of the boat is calculated in the range of 11-18% in Bodrum Gulet and transom stern type sailing yachts, while this range increases to the range of 14-21% in the motor yacht types examined. These values will contribute to naval architecture, yacht interior partitioning and design processes in the preliminary design process of yacht design.
