In this paper, a comparative study of the performance of stern interceptors of an OPV type vessel is presented. The study was developed using numerical CFD simulations to estimate the resistance, which allowed calculation of the fuel consumption for the operating profile. Six interceptors, with chords between 65 and 340 mm, were analyzed for 7 speeds between 8 and 22 knots. The results indicate there is resistance reduction for speeds above 18 knots. For 20 knots, corresponding to the maximum speed of the operational profile, the 200 mm chord interceptor was the one that produced the greatest reduction in resistance, however this speed corresponds only to 10% of the operating time. The sum of the results for the operational profile, showed that the 65 mm interceptor was more efficient for economic benefits over the speed range, however fuel saving is modest, considering the high budgets required to operate these vessels. Other aspects are to be considered for decision making of the inclusion of the interceptor.
