Question 2303 Deck Safety

The correct answer is D) 65 tons. To determine the amount of ballast needed, we need to use the information provided about the vessel's drafts and the location of the LCG of the forepeak. Using the formulas and tables in Section 1 (the blue pages) of the Stability Data Reference Book, we can calculate the amount of ballast required to achieve the desired 18-inch drag. The other options are incorrect because they do not accurately reflect the amount of ballast needed to achieve the target draft. The correct calculation, based on the given information, shows that 65 tons of ballast must be pumped into the forepeak to obtain the desired 18-inch drag.
