This article present results of the comparison between numerical simulation (utilizing Computational Fluid Dynamics) and towing tank experiment of the multihull vessel. Effect of the symmetry plane boundary condition on the resistance has been investigated. Reynolds-Averaged Navier Stokes equations with k-𝜔 turbulence model has been used to calculate resistance of the hull with two degrees of freedom (2-DOF). Calculation has been done using OpenFOAM software package. Governing equations of fluid motion, together with the concept of the mesh and boundary condition has been presented in the first section of this work. Conclusion about calculating resistance of the multihull vessels has been made, after short presentation of the results.
