Question 10 Deck General

The correct answer is D) 1070 tons each. To determine the amount of ballast required in tank No. 5 (P & S), the key information needed is the vessel's loaded drafts (17'-00" forward and 22'-06" aft) and the grain's test weight (33 lbs). Using the Guidance Manual for Loading the M.V. Grand Haven, the required ballast can be calculated based on the vessel's displacement and the grain's test weight. The other options are incorrect because they do not accurately reflect the ballast required to maintain the specified drafts for a vessel loaded with 33 lbs grain. Option D, 1070 tons each, is the correct answer as it provides the appropriate amount of ballast necessary to achieve the desired drafts.
