Sažetak
The classical method of inclining experiments has been used to determine the position of the ship’s
vertical center of gravity for many years. The method contains some basic assumptions, which is why
the accuracy of the method has been debated in the last few years. Modern ships often have chines,
or pronounced flare at fore and aft extremities, that can lead to a significant change in the waterline.
The position of the metacenter changes on these ships as they incline. Therefore, the calculation of
the ship’s center of gravity by the classical method may be inaccurate.
In this paper, three different methods that are not based on the assumption of an unchanged metacenter
are examined. Using a graphical, polar, and general method, the position of the ship’s center of gravity
system can be determined for any ship without determining the position of the metacenter. The three
methods mentioned in this paper were observed and tested on four different ships. In addition, the
results of the classical method are compared with the results obtained from recently developed methods.
