This paper presents the results of an experimental investigation of the wake resistance component measured on two models of a ship with wide beam and shallow draft (Cb=0.55). These models had the same forebody shape but they had different afterbody shapes. In the Tsu Ship Model Basin, resistance tests, wake survey at 0.5L_<pp> behind A.P. of models and wave pattern measurements were carried out together with a supplemental wake survey near the stern of the models. It was found that on both models the sum of the wake resistance obtained by the wake survey and the wave pattern resistance obtained by wave pattern analysis agreed well with the resistance derived from force measurement. In the head loss distribution at 0.5L_<pp> behind A.P., the center peak, the inner side peaks and the outer side peaks were observed within the breadth of the models. The resistance component due to the stern wave breaking was separated from the wake resistance by separating the outer side peaks from the other peaks of the head loss distribution.
