Question 608 Deck Safety

The correct answer is C) Use the hydrostatic tables and enter with the mean draft before grounding and the mean draft after grounding. This is the correct answer because the weight of the vessel supported by the ground when it has run aground can be determined by using the hydrostatic tables. The hydrostatic tables provide the displacement of the vessel at different drafts, so by entering the mean draft before grounding and the mean draft after grounding, you can determine the change in displacement, which represents the weight of the vessel supported by the ground. The other options are incorrect because option A requires extensive calculations beyond what is typically expected of a ship's officer, option B uses an incorrect formula, and option D requires additional information that may not be readily available.
