The correct answer is B) 240 tons. To explain the reasoning: The vessel's draft is 24'-06" forward and aft, and the MT1 (Moment to Trim 1 inch) is 1000 ft-tons. To achieve a 2-foot drag, the vessel needs to be loaded with enough cargo in number 4 hold, which is 100 feet abaft the tipping center, to create the necessary moment to achieve the desired 2-foot drag. Based on the given information, the correct amount of cargo to be loaded in number 4 hold is 240 tons. The other options are incorrect because: A) 120 tons would not create enough moment to achieve the 2-foot drag. C) 300 tons would be an excessive amount of cargo, creating more than the necessary moment. D) 480 tons would be too much cargo, resulting in a significantly deeper draft than the desired 2-foot drag.
