Popis:	The flow around a ship's rudder has been modeled using the vortex lattice method. The technique has been used to study the forces, particularly the side force, developed by the rudder in uniform and nonuniform flow. The model was extended to include the effect of a plate above the rudder in order to simulate the hull. A final part of the work was a study of the effect of the deadwood ahead of therudder. The results obtained from the calculations have shown that a small side force can be created if the rudder is placed symmetrically along the propeller axis when the gap between the top of therudder and the hull is not large. In addition, it was found that a side force could be generated by the proximity of the rudder to the deadwood.
