Studies on Relationship between Water Surface behind Stern and Stern End Form of Fine Ships

In most of the recent ocean going fine ships such as container ships, the transom stern is adopted, which enables to obtain wider waterplane area for necessary stability than the cruiser stern. Wider transom stern end, however, increases disturbance on water surface behind the stern end (hereafter call “stern wave”) and accordingly hull resistance. The method of transom stern design without increasing the stern wave is a key issue in hull form design for such ships. This paper discusses the relationship between the transom stern end form and the stern wave based on the model test and theoretical calculation.
