Abstract: The distribution of singularities (i.e. source, sink and dipole) representing a ship’s hull has played an important role on studying the wave resistance in naval hydrodynamics. Based on the theoretical wave resistance formula from linearized free surface theory, six different wave resistance expressions in terms of three wave components along a longitudinal cut parallel to the ship’s course are presented. To demonstrate the numerical accuracy of these wave resistance expressions, the analysis has been applied to the theoretical wave profiles generated by a submerged point dipole and the results are compared to the known theoretical value.
