Resistance Characteristics of Fishing Boats Series of ITU
Abstract:This paper presents the results of the resistance and propulsion tests carried out during the development of the Fishing Boat Hull Form Series of ITU, providing the means of designing modern fishing boats capable of operating in the Black Sea, Marmara Sea, Aegean Sea, and the Mediterranean Sea. Initially, nine modern hull forms were generated using the hull forms of the traditional Turkish fishing boats. The model resistance tests of these fishing boats were carried out in the lightship, loaded, and highly loaded conditions. In the present paper, these hull forms are introduced, followed by a systematic presentation of comparative results illustrating the scale effects and the extrapolation diagrams, the influence of the block coefficient, the length to beam ratio, the type of stern, the shape of chine and the fore and aft trim on viscous resistance (form factor k), and wave-making resistance (wave-making resistance coefficient C W). The findings on the effects of some appendages such as the rudder, the heel of the rudder and the stern tube on the viscous resistance (form factor k), and the total resistance (total resistance coefficient C Ts) are also illustrated. Finally, a general discussion of the results obtained from the resistance tests, wake measurement tests, and flow visualization tests are presented.
