Question 2427Deck Safety70% to pass

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 holds 1 and 2 flood, the vessel will sink if the permeability exceeds what percent?

AI Explanation
The correct answer is C) 32%. The floodable length curve in the Stability Data Reference Book represents the maximum allowable permeability for a vessel to remain afloat. If the curve represents 45% permeability and the vessel can withstand 1 and 2 compartment flooding, then the vessel will sink if the permeability exceeds 32%. This is because the vessel can only withstand up to 45% permeability, and if the actual permeability exceeds 32%, the vessel will no longer be able to remain afloat with 1 or 2 compartments flooded. The other answer choices are incorrect because they do not accurately represent the maximum allowable permeability for the given scenario based on the information provided.
