Abstract

A study of hull form improvement for a trawler from resistance point of view has been carried out numerically. Both resistances in calm water and added resistance in waves are considered. Wave making resistance in calm
water is calculated by a Rankine source distribution method. Added resistance in waves is predicted by the radiated energy method where ship motions are calculated by a strip theory. Based on the base hull, the longitudinal position of the centre of gravity of the vessel and a parameter to modify the hull form in the forebody are used to establish a response surface for the total resistance. An improved hull form and loading condition is found from the response surface in the parametric space, and a resistance reduction of 4.7 percent is achieved. Detailed numerical method for the prediction is presented.
