The theoretical study on the wave conditions of critical navigation of a single screw container ship (Lpp=175m, Cb=0.575) has been carried out from the viewpoint of structural seaworthiness in longitudinal strength. The wave conditions of critical navigation in the present paper are given in form of combination of significant wave height and average wave period of short-term seaway in which the sum of maximum whipping bending moment due to slamming and maximum wave bending moment at midship attaint to a given longitudinal strength in consideration of still water bending moment. It is found from the results that the navigable wave conditions at higher ship speed in head sea condition are governed mainly by whipping bending moment, in following sea condition by wave bending moment, so that the magnification of longitudinal strength of ship hull can't extend them in head sea condition effectively.
