Proper estimation and calculation of ship resistance, is an elemental step in the process of ship design. It is mandatory to properly calculate the various forms of resistant forces (which include Frictional Resistance, Wave Resistance, Wave Making Resistance, Eddy Making Resistance etc. ) in order to determine the minimum Power requirements of the vessel in accordance with its Principal Particulars. Resistance calculation is a prerequisite to choose suitable engine and other propulsion equipment for the vessel. There are various methods available for calculations in this field, which include statistical, numerical, empirical methods and also computerized models and simulations. In our findings below, we have attempted to make a comparative study of the results attained by using these different methods on a hull. At first, the nature and advent of the various resistance components are described briefly. Following on, resistance parameters are attained from each of the models over a given range of ship speed. The results can be compared for insight into the effectiveness of each method and for choosing an optimal method for the respective vessel.
