Abstract

This paper examines the effect of adding Interceptor to ship resistance and ship lift force. The research was carried out by making a model of the Patrol 40 trim by stern without an Interceptor and with the addition of an interceptor with Maxsurf software, then tested with Fine Marine (Numeca) software. The test results showed a decrease in resistance after the addition of the Interceptor at a speed of 12 knots decreased by 16,196 kN or 42.9%, at a speed of 18 knots decreased by 86.356 kN or 63.9% and at a speed of 24 knots decreased by 122,699 kN or 62,92%. The lift force generated at a speed of 12 knots 1,134,977 kN or the stern rises 0.2 cm, at a speed of 18 knots 1,135,598 kN or the stern rises 20.1 cm and at a speed of 24 knots 1,132,403 kN or the stern rises 32.5 cm.
