Question 2577 Deck Safety

The correct answer is D) Tanks: DB4, DB7. To increase the calculated GM (Metacentric Height) from 4.8' to 5.8', you need to shift the vessel's weight distribution to raise the center of gravity (G). Based on the information provided in the Stability Data Reference Book, ballasting tanks DB4 and DB7 would be the most effective way to achieve this. The other options are incorrect because they would not provide the desired increase in GM. Ballasting tanks DB6 and DT7 (A), DB2 and DB6 (B), or DB2 and DB5 (C) would not result in the required increase in GM from 4.8' to 5.8'.
