Abstract
This paper studied experimental and numerical analyses and design of CFRP rudder with different aspect ratios for 33 feet catamaran racing yacht. To design the effective aspect ratio of rudder, hydrodynamic forces were measured with driving model ships in water channel. Hydrodynamic forces were calculated by the prediction method suggested in International Towing Tank Conference 1978. Finite element method was also applied to examine the structural strength of rudder. Finally, the proper aspect ratio of CFRP rudder was verified through experiments and simulations to satisfy the performance required in racing yacht.
