Fishing vessels experience significant hydrodynamic changes when towing a trawl net, which can impact their stability, maneuverability, and fuel efficiency. Understanding these effects is crucial for enhancing vessel performance and ensuring safe and efficient fishing operations. This study explored effects of a trawl net on hydrodynamic forces exerted on a fishing vessel. The interaction between the vessel and the trawl net introduces additional resistance, affects maneuverability, and alters the overall dynamic behavior of the system. To analyze these effects, a model test was conducted to predict hydrodynamic forces acting on the fishing vessel when a trawl net was towed behind the model ship. An Arctic krill trawler was selected as the target for this study. A series of captive model tests, including static drift tests, circular motion tests with drift, and dynamic tests were carried out with or without the towed trawl net to determine hydrodynamic forces. Consideration was also given to effects of drift angle, yaw rate, and acceleration. The trawl net significantly impacted the ship's hydrodynamic forces, especially at large drift angles and high yaw rates, creating additional drag in the water and increasing the ship's hydrodynamic forces. Hydrodynamic coefficients were estimated in relation to the effect of the trawl net. These results provide insights into the optimization of fishing operations by improving vessel performance and efficiency under towing conditions through modifications in hydrodynamic forces induced by a trawl net.
