Question 2432 Deck Safety

The correct answer is D) 78 percent. The floodable length curve in Section 1 of the Stability Data Reference Book represents the maximum allowable permeability for a vessel with a flooded compartment. If the curve represents 45 percent permeability and number 3 hold floods, the vessel will sink if the permeability exceeds 78 percent. This is because the vessel's stability and ability to remain afloat is compromised when the actual permeability of the flooded compartment exceeds the maximum allowable permeability shown on the curve. The other options are incorrect because they do not correspond to the maximum allowable permeability for the given scenario. The floodable length curve is a critical tool for ensuring vessel stability and safety, and understanding how to interpret it is essential for passing the US Coast Guard Captain's License Examination.
