In this paper, the effects of stern bulb skeg on ship's maneuverability were investigated. The skeg is one of the afterbody appendages and generally fitted below the stern bulb, and it plays a role as the course stabilizing fin. To examine the effects of stern bulb skeg on ship's maneuverability, PMM tests of four ships with and without stern bulb skeg were carried out and analyzed. The results showed that the stern bulb skeg mainly has influence on the linear hydrodynamic coefficients of hull. The effects of stern bulb skeg on the linear hydrodynamic coefficients of hull were expressed as empirical formula through regression analysis. The simulation results using this formula were compared with model test results.
