Guideline for Preliminary Design Phase of Trawler Type Yachts

Abstract

Yacht design is a multidisciplinary process that consists of set of iterative sub-processes. The main aim of the whole process is to reach the optimum design that satisfies not only the engineering-related requirements, but also the user’s expectations. In the preliminary design process, determination of the type and the main dimensions of the yacht according to the user’s preferences is followed by the processes such as the general arrangement plan, determination of the hull form and superstructure design, estimation of hydrostatic and hydrodynamic characteristics, etc. In this research, it is aimed to obtain a parametric design framework which enables to reach hull form characteristics, layout parameters and resistance estimation values with respect to various speeds, only by using only LOA of trawler type motor yachts. In this content, 26 trawler type motor yachts were investigated and their hull were modeled for speed-resistance calculations. As a result of the research, graphics and tables were presented that allow to reach the characteristic parameters, which are important in terms of design and engineering, by using only the LOA value in the preliminary design phase of the trawler type motor yachts.
