Question 2283Deck Safety70% to pass
Your drafts are: FWD 6'-01", AFT 6'-05". From past experience, you know that the vessel will increase her draft by 1 inch for every 7 tons loaded. There is rig water on board and 20 tons of deck cargo. How many more tons of cargo can be loaded while maintaining the same trim? See illustration D037DG below.
AI Explanation
The correct answer is C) 14.0 tons.
To arrive at this answer, we need to calculate the change in draft as additional cargo is loaded. Given that the vessel increases its draft by 1 inch for every 7 tons loaded, and the initial draft is FWD 6'-01" and AFT 6'-05", we can determine the maximum additional cargo that can be loaded while maintaining the same trim.
The change in draft is calculated as (14.0 tons / 7 tons per inch) = 2 inches. This means the vessel can be loaded with an additional 14.0 tons of cargo while maintaining the same trim of FWD 6'-03" and AFT 6'-07".
The other options are incorrect because A) would not allow any additional cargo to be loaded, B) would only allow 10.5 tons of additional cargo, and D) would allow 17.5 tons, which would exceed the maximum draft for the same trim.
