## Abstract
Abstract The engine on a fishing vessel is the main equipment that is assembled in a vessel’s machining system. The vessel’s engine, as the main driving force, is coupled with a propeller, which functions to provide thrust to the vessel. The efficiency and effectiveness of the propeller used on fishing vessels depend on the dimensions of the propeller and the type of fishing gear used, as well as the shape and size of the hull. The correlation between vessels, engines, and propellers in vessel planning determines the successful fishing operation. The objective of this study was to examine the geometrical relationship of the purse seine hull to the effectiveness and efficiency of the propeller. The analysis was conducted on nine samples of purse seiner operating in the Flores Sea through numerical simulations. The sample vessel designs were drawn from the vessel offset data using the max surf software to obtain the shape of the hull. Furthermore, the vessel shape specifications were simulated with the propeller technical specifications to obtain propeller efficiency values based on the shape of the hull. The results showed that the pressure value on the propeller used on purse seiners with round bottom was lower than the pressure experienced by the propeller on a U-bottom. Propeller efficiency values were higher on round bottom purse seiners than U-bottom forms. This value illustrates that the propeller thrust was greater in round-bottom vessels. This is probably indicated that the value of resistance on the U-bottom hull form was greater than the round bottom hull shape.
