Question 4878Deck General70% to pass

The COASTAL DRILLER has a trim of 2.13 feet by the stern. The draft at the forward draft marks is observed to be 8.0 feet. The draft at the center of flotation is _______________.

AI Explanation
The correct answer is D) 9.42 feet. The draft at the center of flotation can be calculated using the formula: Draft at center of flotation = Draft at forward marks + Trim. Given that the trim is 2.13 feet by the stern, and the draft at the forward draft marks is 8.0 feet, the draft at the center of flotation can be calculated as 8.0 feet + 2.13 feet = 9.42 feet. The other options are incorrect because they do not properly account for the trim of the vessel. Option A) 7.00 feet is too low, Option B) 8.58 feet is too low, and Option C) 9.00 feet is also too low compared to the correct calculation.
