Reconstruction of Hull Form of Traditional Croatian Fishing Vessel and Prediction of Effective Power

Recently, an increasing attention is given to preservation and popularization of Croatian traditional boat building, which plays an important role in Croatian cultural and national heritage. Reconstruction and revitalization projects of individual historical vessels are key factors within preservation process, where the lack of technical documentation is one of the main issues. In this paper, a simple and effi cient procedure for taking off sets of a traditional fi shing vessel guc is presented to document and preserve the traditional Croatian vessel form. A 3D model of a guc is generated using the points on the hull surface obtained by the manual measurement and a fairing process. Numerical simulations of the resistance test for a fi shing vessel are carried out for a wide range of speeds, and the curve of eff ective power as a function of vessel speed is provided.
