Question 2309Deck 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 18 inches? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)
AI Explanation
The correct answer is A) 105 tons.
To determine the amount of ballast required, we need to use the information provided about the vessel's drafts and the location of the LCG of the forepeak. The Stability Data Reference Book in Section 1 (the blue pages) provides the necessary information and formulas to calculate the required ballast.
Given the vessel's drafts (FWD 14'-04", AFT 17'-08") and the desired 18-inch increase in draft, we can calculate the amount of ballast required to achieve the desired 18-inch increase in draft. The calculation shows that 105 tons of ballast must be pumped into the forepeak to reach the target 18-inch increase in draft.
The other options (B, C, and D) are incorrect as they do not accurately reflect the amount of ballast required based on the provided information and the calculation using the Stability Data Reference Book.
