Your drafts are: FWD 6'-02", AFT 6'-06". From past experience, you know that the vessel will increase her draft 1 inch for every 5 tons loaded. There is rig water on board and 15 tons of deck cargo. How many more tons of cargo can legally be loaded and still maintain the same trim? See illustration D037DG below.

A none
B 10 tons
C 20 tons
D 5 tons
AI Explanation

The correct answer is D) 5 tons. The reasoning is as follows: 1. The vessel's current draft is 6'2" forward and 6'6" aft, indicating a trim of 4 inches by the stern. 2. With 15 tons of deck cargo on board, the vessel will increase its draft by 3 inches (1 inch per 5 tons). 3. To maintain the same trim, the vessel can load 5 additional tons of cargo, which will increase the draft by 1 inch, keeping the same 4-inch trim. 4. The other options are incorrect because loading 10 or 20 tons would exceed the allowed 4-inch trim, while loading no additional cargo would not fully utilize the vessel's capacity.
