Question 4884 Deck General

The correct answer is B) true mean draft. Weights added or discharged at the center of flotation on a vessel will change the true mean draft of the vessel, but will not affect the list or trim. This is because adding or removing weight at the center of flotation does not create any moments that would cause the vessel to list or trim. Instead, it simply changes the overall displacement of the vessel, which directly impacts the true mean draft. The other options, TPI (Tons Per Inch) and list, are not affected by weight changes at the center of flotation.
