Question 163 Deck General

The correct answer is C) 1645 tons. The Guidance Manual for Loading M.V. GRAND HAVEN provides the recommended hatch loading sequence and the desired mean keel draft of 24'-10". Following this guidance, the maximum amount of iron ore that can be loaded through hatch No. 20 while using a single belt loader is 1645 long tons. The other options are incorrect because they do not match the specific guidance and constraints provided in the question. Option A (1540 tons) and B (1590 tons) are too low, while option D (1670 tons) is too high for the given conditions.
