Ferry boat operation, particularly in Indonesia is increasing widely. Research on the boat by naval architects is intensifying as well. The aim of the study was to determine the effect of rudder on ship heeling manoeuvre. Matrix Laboratory (MATLAB) simulation was used to predict the heeling angles. The simulation utilized model basedudon the concept of Mathematical Modelling Group (MMG). The model includes theory, separating components of hull equations, propeller and rudder as well as their interaction (hull, propeller, and rudder). The simulation results are compared with sea trial performance of ferry of KMP Sultan MURHUM. It was obtained that the heel angle of 3.10 , 3.15, 3.20 degrees for 1.632, 1,819, 2,078 square meter rudder area respectively. The results indicate that the greater the rudder area the greater the heel angle during the manoeuvre.
