A 14 tons
B 18 tons
C 24 tons
D 33 tons
AI Explanation

The correct answer is B) 18 tons. The explanation is as follows: 1. The given information states that the vessel's draft is 6'-00" forward and 6'-06" aft, indicating a trim of 6 inches by the stern. Additionally, the vessel will increase its draft by 1 inch for every 6 tons loaded. 2. With 17 tons of deck cargo and rig water on board, the vessel can load an additional 18 tons of cargo and still maintain the same trim. This is because the additional 18 tons will increase the draft by 3 inches (18 tons / 6 tons per inch), keeping the vessel's trim at 6 inches by the stern. 3. The other answer choices are incorrect because they do not accurately account for the increase in draft based on the given information. Option A (14 tons) is too low, while options C (24 tons) and D (33 tons) are too high and would result in a change in the vessel's trim.
