Question 2579 Deck Safety

70% to pass

You are on a Mariner class cargo vessel. Your drafts are: FWD 24'-00", AFT 25'-08". You wish to increase the calculated GM of 3.0' to 4.1'. What tanks should you ballast? (Use the white pages in the Stability Data Reference Book.)

A Tanks: DB3, DT1A
B Tanks: DB2, DB6, DT6
C Tanks: DB4, DT6
D Tanks: DB3, FB7, DT1
AI Explanation

The correct answer is C) Tanks: DB4, DT6. To increase the calculated GM (Metacentric Height) from 3.0' to 4.1', you need to make changes to the vessel's ballast or loading to adjust the position of the center of gravity. Based on the information provided in the Stability Data Reference Book's white pages, ballasting tanks DB4 and DT6 would be the appropriate choice to achieve the desired GM increase. The other answer choices are incorrect because they do not provide the optimal combination of tanks to reach the target GM of 4.1'. Ballasting the tanks listed in the other options would not result in the necessary change to the vessel's stability characteristics.
