Question 2312Deck Safety70% to pass
Your vessel's drafts are: FWD 14'-04", AFT 17'-08". 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 2 feet? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)
AI Explanation
The correct answer is D) 75 tons.
To determine the amount of ballast required, we need to use the principles of ship stability and the information provided in the Stability Data Reference Book, Section 1 (the blue pages).
Given the vessel's drafts (14'4" forward and 17'8" aft) and the location of the LCG of the forepeak (200 feet forward of amidships), we can calculate the change in draft required to achieve a 2-foot drag. The Stability Data Reference Book provides the necessary information to determine the amount of ballast required to achieve this change in draft, which is 75 tons.
The other options (A, B, and C) are incorrect because they do not accurately reflect the amount of ballast required to achieve the desired 2-foot drag, as per the information in the reference material.
