This paper presents the results of manoeuvring model tests and CFD calculations for a twin-screw ferry with different skeg lengths. The impact of these skeg configurations on different aspects of ship hydrodynamics, such as hull resistance, turning ability and low-speed manoeuvring, are analyzed and discussed. It is shown how the skeg influences in both positive and negative ways the hydrodynamic design of the ship, with particular attention to ship manoeuvrability.
