Question 2307Deck Safety70% to pass
Your vessel's drafts are: FWD 19'-03", AFT 21'-03". The LCG of the forepeak is 200 feet forward of amidships. How many tons of ballast must be pumped into the forepeak in order to have a drag of 18 inches? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)
AI Explanation
The correct answer is B) 31 tons.
To determine the amount of ballast needed, we need to use the formula for the change in draft given in the Stability Data Reference Book, Section 1 (the blue pages). The formula is: change in draft = (change in displacement) / (LBP x beam x CB).
Given the forward and aft drafts, we can calculate the change in draft needed to reach 18 inches. Using the provided LCG of the forepeak, we can then calculate the change in displacement required, which corresponds to 31 tons of ballast.
The other answer choices are incorrect because they do not accurately reflect the change in displacement required to achieve the target 18-inch draft.
