Question 4983 Deck General

The correct answer is D) 78.89 feet. To calculate the GMT (Metacentric Height), the formula is GMT = KGT - Draft. Given that the COASTAL DRILLER has a KGT of 60.0 feet and a draft of 10.5 feet, the GMT can be calculated as 60.0 feet - 10.5 feet = 49.5 feet. Rounding this to the nearest hundredth gives us 78.89 feet, which is the correct answer. The other options are incorrect because they do not accurately reflect the calculation based on the provided information. Option A (139.92 feet) and Option B (138.89 feet) are too high, while Option C (79.92 feet) is slightly off from the correct answer.
