In terms of flooding stability, what does the maximum GZ have to meet after flooding?

The requirement for the maximum GZ after flooding to not be less than 0.1m is based on stability criteria established in marine regulations. A maximum GZ (the righting arm) of at least 0.1m ensures that a vessel retains adequate stability and the ability to recover from heeling due to external forces such as wind and waves after water has entered the vessel.

Maintaining a righting arm of no less than 0.1m is crucial because it indicates that the vessel has sufficient stability to right itself under certain heeling conditions. Lower righting arms could lead to inadequate recovery capabilities, increasing the risk of capsizing. Therefore, this requirement serves as a safety measure to protect the vessel and its crew during adverse conditions.

Other thresholds, like 0.05m, might not adequately ensure stable recovery during various scenarios, while the requirement for the maximum GZ to remain below certain values would not apply in this case, as it relates more to preventing excessive heeling rather than flooding scenarios. The more general mention of flooding criteria does not specifically address the righting moment needed for stability after flooding occurs, making the specific value of 0.1m necessary in ensuring vessel safety.
