Reliability of attribute prediction in small craft concept design

A multi-attribute concept design procedure, as developed at the University of Zagreb, is applied to the small craft. Specialized concept design models of several generic types, e.g. mono-hull ferry, catamaran ferry, fishing vessel, fast SAR, patrol and paramilitary craft, were developed and included into a multi-attribute design procedure. In the present paper we address concept design model of the fast mono-hull type service vessels. Calibration of the model is an important task if reliable results are expected. Here we will deal with the reliability of attribute prediction. Practical parametric equations for attribute prediction, based on the previous work, were developed from published empirical methods, from analytical first principle methods, and from the study of selected database vessels. The results of attribute prediction were systematically com-pared to database values. Best fitting equations are presented in order to make them widely available to small craft designers.
