Question 2580 Deck Safety

The correct answer is B) Tanks: DB4, DT6. To increase the GM (Metacentric Height) from 2.9 feet to 3.9 feet, you need to shift weight from the higher positions to the lower positions. By ballasting tanks DB4 and DT6, you can effectively lower the center of gravity and increase the GM as required. The other options are incorrect because: A) Tanks DB2, DT1, and DT6 may not provide the necessary change in weight distribution to achieve the desired GM increase. C) Tanks DB6 and DT7 are not the optimal choices to increase the GM from the given conditions. D) Tanks DB3, DB5, and DT8 are not the most effective combination to achieve the desired GM increase.
