Abstract

The fisheries sector is a vital element of the maritime economy; however, fishing vessel operations are often hindered by stability issues caused by high wave oscillations. This study aims to analyze the effectiveness of a retractable bow foil modification in reducing the Response Amplitude Operator (RAO) values of a fishing vessel integrated with a dihedral bulbous bow. The analysis focuses on a performance comparison between the baseline vessel and variations using NACA 0010 and NACA 0015 profiles to evaluate damping capabilities in rotational modes (Roll, Pitch, Yaw) and translational modes (Surge, Sway, Heave) under following seas (0°) and beam seas (90°) conditions. The research methodology involves numerical simulations across a wave frequency range of 2.24 to 5.24 rad/s to identify the vessel's dynamic Response characteristics. The results indicate that the NACA 0015 profile is the most optimal configuration for reducing rotational motions, achieving an average RAO reduction of 71.9% in Roll mode and 97.4% in Yaw mode under beam seas conditions. Conversely, for translational stability, the NACA 0010 profile proves superior due to its more stable and consistent damping characteristics across various frequencies, reducing Heave and Surge motions by up to 35.1% and 40.6%, respectively. This study concludes that the selection of a bow foil profile should be based on the vessel's operational priorities; NACA 0015 is recommended for directional stability and extreme rolling, while NACA 0010 is suggested for maintaining vertical and longitudinal comfort. These findings provide a significant contribution to the design of safer and more efficient fishing vessels for navigating moderate to extreme sea conditions.
