Improvement of the Fishing Vessel Concept Design Model

Latest improvements of the fishing vessels concept design model are presented. New research and a wider data base, made it possible to introduce new parameter relations in the design model. Only newly included material is presented. The model is aimed primarily at the Adriatic type of fishing vessels with the length of up to 30 m. Steel, aluminum, timber or glass composites are possible choices for the hull structural material. Weight estimating is based on plating areas and selected building material. A ship cost estimating procedure is developed. Complete new regression analysis of the UBC model series was performed in order to enable resistance prediction of the low length to beam ratio hulls, since large beam is a trend in modern fishing vessels. Freeboard at the bow is analyzed and appropriate relations found. Statistical relations of design parameters were developed in order to define constraints to the model more realistically.
