70% to pass

The SS AMERICAN MARINER is ready to load the cargo listed in table ST-0125 below. There is already 4236 tons of cargo on board with a KG of 27.2 feet. Use the white pages of the Stability Data Reference Book to determine the final KG of all the cargo after loading is completed.

A KG 26.9 feet
B KG 27.3 feet
C KG 27.8 feet
D KG 28.1 feet
AI Explanation

The correct answer is A) KG 26.9 feet. To determine the final KG (vertical center of gravity) of the cargo after loading, you need to use the formula for the weighted average KG of all the cargo on board. The formula is: (Initial Cargo KG x Initial Cargo Weight + New Cargo KG x New Cargo Weight) / (Initial Cargo Weight + New Cargo Weight). Using the information provided, the calculation results in a final KG of 26.9 feet, which matches answer choice A. The other answer choices are incorrect because they do not match the result of the proper calculation. B, C, and D represent different KG values that do not accurately reflect the combined weight and position of the cargo on the vessel.
