Question 2343Deck Safety70% to pass
The maximum draft of the SS AMERICAN MARINER cannot exceed 30'-01" in order to cross a bar. The present drafts are: FWD 29'-04", AFT 30'-06". 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 B) 100 tons.
To achieve the maximum draft of 30'-01", the aft draft needs to be reduced from 30'-06" to 30'-01". This can be done by ballasting the forepeak with seawater to increase the forward draft from 29'-04" to 30'-01".
Using the white pages of the Stability Data Reference Book, the minimum amount of seawater required to ballast the forepeak and achieve the desired draft condition is 100 tons.
The other options are incorrect because they do not represent the minimum amount of seawater required to reach the target draft.
