Question 2282 Deck Safety
70% to passYour drafts are: FWD 6'-01", AFT 6'-05". 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.
The correct answer is B) 10 tons. The explanation is as follows: 1. The given information states that the vessel's draft is 6'-01" forward and 6'-05" aft, with 15 tons of deck cargo on board. Based on the provided information, the vessel will increase its draft by 1 inch for every 5 tons loaded. 2. To maintain the same trim, the vessel can only load an additional 10 tons of cargo, as this will increase the draft by 2 inches (10 tons / 5 tons per inch = 2 inches), resulting in a draft of 6'-03" forward and 6'-07" aft, which is the same trim as the initial condition. 3. The other answer choices are incorrect because: A) 35 tons would increase the draft by 7 inches, which would not maintain the same trim. C) 20 tons would increase the draft by 4 inches, which would not maintain the same trim. D) None is incorrect because the vessel can legally load an additional 10 tons of cargo.
