Question 2433 Deck Safety

The correct answer is C) 67 percent. The floodable length curve in the Stability Data Reference Book represents the maximum percentage of the vessel's length that can be flooded before the vessel sinks. If the curve is based on 45 percent permeability and number 2 hold floods, the vessel will sink if the permeability exceeds 67 percent. This is because the curve shows the maximum floodable length for a given permeability, and if the actual permeability exceeds 67 percent, the flooding would cause the vessel to sink. The other options are incorrect because 52 percent (A) and 60 percent (B) are lower than the actual threshold of 67 percent, while 76 percent (D) is higher than the threshold.
