Comparative Study of Ship Resistance between Model Test and Empirical Calculation of 60 GT Fishing Vessel

The main objective of this paper is to study and research on the ship resistance for 21.98 m single screw fishing vessel. The ship resistance is normally determined by using model test in a towing tank. However it can also be predicted by using, empirical formula or statistical data. Prediction in the preliminary design stage is one of the important practice and research in ship design. Several methods can be used in the ship resistance prediction depends on the type of the ship and the limitation of the methods. Consequently using existing method, the resistance of 21.98 m fishing vessel will be investigated. A prediction for fishing vessel resistance, van Oortmersen method shows the same result with model test result. The rest method compromises with model test can be used for calculating resistance of fishing vessel. Naval architecture task is to ensure that, within the bounds of the other design requirement, the hull form design of propulsion and the procedure will be the most efficient in terms of hydrodynamics. The final test of the ship will perform at the required speed with minimum of shaft power, and the problem is to achieve the best combination of low resistance and high efficiency propulsive. In general, this can only be achieved by matching precisely the hull and propeller
