Abstract
By investigating the research in the field of planing vessels, limited research has been conducted to investigate the behavior and other hydromantic parameters. Given that such vessels can have better hydrodynamic performance than similar vessels, research and study is one of the needs and priorities of designers. With this purpose, this study examines the effects of the transverse steps hydrodynamic element on the single hull planing vessel. Since researchers in this study are looking for general and not specific results, empirical research conducted on the Friedzema model, at three different deaerise angles as well as in different speeds and geometric parameters (different heights and locations steps) and at the exit of the experimental part of the research, the location and heights of the steps are expressed at different angles. Other output results of the present study are the process of building a new model of vessel that can simultaneously combine several models.
