During the currently ongoing development of methods for assessing the safety of ships, it is imperative that a compromise between the accuracy of the results and the accessibility of obtaining results is reached. This paper shows the calculations of a theoretical hull against damage stability regulations as included in SOLAS 2020, ICLL 66/88 as amended in 2003 and MARPOL 78. The rules included in the currently valid regulations require certain righting arm curve properties from vessels before and after potential damage, which does not pose a high difficulty level to engineers. However, for many engineers and scientists working with these rules, it is unclear what kind of behavior (particularly roll motion) these righting arm curve parameters correspond. In this paper, a correlation between the required GZ properties and the actual roll motion of a ship in waves, as calculated with the well-established method proposed by the ITTC, is revealed, and a comparison of the results to the currently in use regulations as well as comparison between the methods themselves is made. The comparison reveals the impact of GZ curve parameters on the roll motion of the ship.
