Indonesia is an archipelagic country with great fisheries potential, facing various problems Fishing boats as the main element in the fisheries sector must have a good propulsion system design. This research aims to improve the efficiency of the ship's propulsion system by analysing the variation of rudder distance with Propeller using CFD (Computational Fluid Dynamics) approach. Before simulating, the validation process has been carried out with a Propeller without a rudder resulting in an error value below 5%. In this study, the distance variation analysed is 10%D to 100%D. The results of this study show that the most optimal steering distance is 40%D with a thrust value of 285.432 N and the torque is 3928Nm. With a relatively low torque value but able to produce a high thrust force, this shows the efficiency of the steering system performance, which in turn can improve the operational efficiency of the fishing boat. The results of the analysis can be used in the design of ship propulsion systems so that they can have an impact on the welfare of fishermen Indonesia.
