Question 2290 Deck Safety
70% to passYour drafts are: FWD 6'-2", AFT 6'-8". From past experience, you know that the vessel will increase her draft 1 inch for every 6 tons loaded. There is rig water on board and 23 tons of deck cargo. How many more tons of cargo can be loaded and still maintain the same trim? See illustration D037DG below.
The correct answer is D) 6 tons. Here's the explanation: 1. The question states that the vessel's draft is 6'-2" forward and 6'-8" aft, indicating the vessel is already trimmed by the stern by 6 inches. With 23 tons of deck cargo on board, the vessel will increase its draft by 1 inch for every 6 tons loaded. Therefore, the additional 6 tons of cargo that can be loaded while maintaining the same trim is the correct answer. 2. The reasoning is based on the principle that the vessel's draft will increase proportionally to the additional weight added. Since the vessel is already trimmed by the stern, adding more weight would further increase the aft draft, affecting the vessel's stability and seaworthiness. 3. The other options are incorrect because they either exceed the amount of additional cargo that can be loaded while maintaining the same trim (A, B, and C) or do not represent the correct amount (C).
