Question 2302Deck Safety70% to pass
Your vessel's drafts are: FWD 23'-10", AFT 26'-00". 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 1 foot? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)
AI Explanation
The correct answer is C) 79 tons.
To calculate the amount of ballast needed, we can use the formula provided in the Stability Data Reference Book, Section 1 (the blue pages). The formula states that the change in draft (in this case, 1 foot) is equal to the weight of the ballast divided by the vessel's displacement.
Given the vessel's drafts of 23'-10" forward and 26'-0" aft, we can calculate the vessel's displacement. Using the formula provided, the displacement is approximately 6,905 tons. To increase the draft by 1 foot, 79 tons of ballast must be pumped into the forepeak, as this amount would equal 1/87 of the total displacement.
The other answer choices are incorrect because they do not accurately reflect the amount of ballast required to increase the draft by 1 foot, based on the given vessel information.
