Abstract

Wave resistance represents a critical component of total ship resistance that significantly in-fluences vessel performance, fuel efficiency, and operational costs in modern naval architec-ture. This investigation evaluates the accuracy and reliability of Maxsurf's computational methods for predicting wave resistance through comparative analysis of monohull and cata-maran configurations using slender body analysis theory. The research methodology em-ployed Maxsurf's Resistance module, which implements Michell's thin ship theory and po-tential flow calculations specifically suited for slender hull forms with length-to-beam ratios greater than 5.0. Two distinct hull configurations were analyzed: an original monohull de-sign and a modified catamaran configuration created by longitudinally cutting the monohull along its centerline. Critical design parameters including displacement, length between per-pendicular (LBP), and beam were maintained constant between configurations to ensure val-id comparative analysis of wave resistance characteristics. Slender body method calculations were performed across a range of Froude numbers to capture resistance behavior in both dis-placement and semi-planing operational regimes. Results demonstrate significant variations in wave resistance coefficients between monohull and catamaran configurations. The study validates Maxsurf's computational accuracy against established naval architecture principles and confirms the software's reliability for early-stage hull form optimization. These findings provide valuable insights for marine designers seeking to optimize hull forms for reduced wave resistance, contributing to enhanced vessel efficiency and sustainable maritime trans-portation. The research establishes a robust framework for comparative resistance analysis and demonstrates the practical application of computational naval architecture tools in mod-ern ship design optimization.
