This report proposes an approximate calculus for calculating normal part of the thrust deduction. The basic integral equation of the present method is deduced from hydrodynamic assumptions of the pressure field about a hull and a properller. The author calculates normal part of the thrust decuction for various hull-forms by the present method, and compares the calculated results with results calculated by the potential flow method or results of the self-propulsion test. These comparison show that the present method is resonable. Calculating time consumed with the numerical method in the present method is less than that in the case of the potential flow method, and application of the present method to the more practical hull-form is easy. Consequence of some numerical results shows that normal part of the thrust deduction is the largest part of the thrust deduction.
