This study presents the influence of the distance between the floats of catamaran for ship calm water resistance. As we know, a catamaran is composed by 2 floats, each float having its own wave systems in calm water. The distance between these floats influences the phenomena that appear due to the composition of the wave systems. The low value of the calm water resistance force is provided by the optimum distance of the floats. In this study, there will be used 3 different distances of the floats for the main speed of the ship. To estimate the ship resistance there will be used RANS equations which provide a good fluid flow in turbulent models.
