Use the floodable length curve in Section 1, the blue pages, of the Stability Data Reference Book. If the curve represents 45 percent permeability and number 4 hold floods, the vessel will sink if the permeability exceeds what percent?
Official USCG Answer & Rule Citation
Correct Answer: Option D — 60
Floodable length calculations for number 4 hold derived from the blue pages establish a maximum allowable permeability threshold of 60 percent for vessel survivability.
