Abstract
In the context of the Polbeng II ship, the addition of a tunnel propeller component has the potential to provide significant benefits in enhancing the ship^s performance in terms of speed and efficiency. By understanding the theoretical foundations and operational principles of tunnel propellers, it is hoped that subsequent research and development can optimize the application of this technology to achieve the best possible results in improving the overall performance of the vessel. The tunnel design examined in this study compares two design models: 50%D and 20%D, relative to the distance from the rudder. The results obtained from these two design models are as follows: the 50%D model tunnel has a flow pressure value of 99.119 pascals and a flow velocity value of 2.035 m/s, while the 20%D model tunnel has a flow pressure value of 96.819 pascals and a flow velocity value of 2.024 m/s.
