Question 2266Deck Safety70% to pass
Your vessel has a forward draft of 26'-11" and an after draft of 29'-07". How many tons of cargo can be loaded before the vessel reaches a mean draft of 28'-06" if the TPI is 69?
AI Explanation
The correct answer is B) 207 tons.
To determine the amount of cargo that can be loaded, we need to calculate the change in draft required to reach the mean draft of 28'-06". The forward draft is 26'-11" and the aft draft is 29'-07", so the mean draft is (26'-11" + 29'-07") / 2 = 28'-03". The desired mean draft is 28'-06", so the change in draft is 28'-06" - 28'-03" = 3".
The change in draft of 3" corresponds to a change in displacement of 207 tons, given the TPI of 69.
The other options are incorrect because they do not accurately reflect the change in displacement required to reach the desired mean draft based on the provided information.
