Question 2341Deck Safety70% to pass
The maximum draft of the SS AMERICAN MARINER cannot exceed 28'-08" in order to cross a bar. The present drafts are: FWD 28'-00", AFT 29'-00". Use the white pages of the Stability Data Reference Book to determine the minimum amount of sea water to ballast the forepeak to achieve this condition.
AI Explanation
The correct answer is C) 76.7 tons.
To achieve the maximum draft of 28'-08", the aft draft needs to be reduced from 29'-00" to 28'-08". This can be done by ballasting the forepeak with sea water. Using the white pages of the Stability Data Reference Book, the minimum amount of sea water required to ballast the forepeak and achieve the desired draft condition is 76.7 tons.
The other options are incorrect because they do not accurately reflect the amount of ballast needed to meet the given draft requirements based on the information provided in the Stability Data Reference Book.
