The primary objective of the interceptor is to control the trim of the vessel, thereby enhancing fuel efficiency and stability. However, at high speeds, the interceptor induces adverse effects. This research aims to mitigate these negative impacts by modifying the geometric configuration of the interceptor. The shape modifications of the rounded interceptor evaluated through numerical simulations include radii of R10.00, R12.50, and R15.00. This study aims to contribute to an enhanced understanding of the effects on drag, heave, and trim performance of the planing hull vessel. The methodology employs a Computational Fluid Dynamics (CFD) approach using Reynolds-Averaged Navier-Stokes (RANS) equations. The simulation verification was conducted regarding prior experimental studies, and the simulation procedures adhered to the guidelines set by the International Towing Tank Conference (ITTC). The interceptor's height is a key factor in reducing trim, heave, and consequently, drag. The modified rounded interceptor effectively reduces drag at high speeds. © 2025, Semarak Ilmu Publishing.
