Question 2300Deck Safety70% to pass
Your vessel's drafts are: FWD 21'-08", AFT 24'-02". 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 15 inches? (Use the selected stability curves in Section 1, the blue pages, of the Stability Data Reference Book)
AI Explanation
The correct answer is C) 82 tons.
To determine the amount of ballast required, we need to use the stability data and the given information about the vessel's drafts and longitudinal center of gravity (LCG) of the forepeak.
Based on the stability data in the reference book, to achieve a 15-inch drag, the vessel would require 82 tons of ballast in the forepeak. This is because the additional weight of the ballast would shift the vessel's center of gravity forward, thereby increasing the draft at the bow and achieving the desired 15-inch drag.
The other options are incorrect because they do not accurately reflect the amount of ballast needed to achieve the specified 15-inch drag based on the provided vessel characteristics.
