When a ship is rolling in waves with so large mean heel angle that her deck edge is immersed, characteristics of the rolling motion, for example the resisting moment, are very much different from those in rolling about an upright condition.
Shipping of a large quantity of sea water brings about instantaneous heeling over 30 degrees occasionally and some ships capsize and the others become upright gradually.
The author describes in this paper some interesting experimental results in relation with abovementioned phenomena, unsymmetrical rolling, and an example of the calculation of resistive moment and forces due to wave making is tabulated for the sake of qualitative apprehension.
