Question 4957 Deck General

The correct answer is D) 26.4 feet. The margin on the maximum allowable KG is calculated by subtracting the vessel's KGT (39.0 feet) from the maximum allowable KG (65.0 feet, as per the stability regulations). This gives a margin of 26.4 feet (65.0 feet - 39.0 feet = 26.4 feet). The other options are incorrect because: A) 3.0 feet is the difference between the vessel's KGT and KGL, not the margin on the maximum allowable KG. B) 3.4 feet is also the difference between the vessel's KGT and KGL, not the margin on the maximum allowable KG. C) 26.0 feet is incorrect, as the correct margin is 26.4 feet.
