No	Authors	General description	Main investigated topic	Year
1	Dongmei et al. [33]	They simulated flow field around the stepped planing hulls based on the FVM (finite volume method) using the Taunton series.	Air cavity	2019
2	Zou et al. [34]	They examined the stern flap and double step as two general potential factors in resistance reduction.	Flap and double step	2019
3	Ghadimi et al. [35]	This paper investigated the performance and hydrodynamic characteristics of a double-stepped planing hull and the effects of adding two steps to the bottom of a monohull.	Double step	2019
4	Kazemi et al. [36]	They studied the effects of weight loading by simulating nonstep and single-step planing hulls with free heave and pitch motions under different weight loadings.	Weight loading	2019
5	Chooran et al. [37]	This work addressed the numerical study of step height effect on hydrodynamic performance of the planing hull.	Height step	2019
6	Najafi et al. [38]	In this paper, hydrodynamic resistance of a single-step planing craft was experimentally investigated under different geometrical and physical conditions. To accomplish this task, a Fridsma body model with varying angles of deadrise was considered.	Deadrise	2019
