Question 4709 Deck General

The correct answer is D) at the center of flotation. The true mean draft of a MODU (Mobile Offshore Drilling Unit) is the draft at the center of flotation. This is because the center of flotation is the point where the buoyant force acts, and it is the location that determines the overall draft of the vessel. The draft at the center of flotation represents the average depth of the vessel in the water, which is the true mean draft. The other options are incorrect because: A) the draft at the center of buoyancy is not the true mean draft, B) the draft midway between forward and aft drafts does not necessarily represent the true mean draft, and C) the draft at the load line is a specific draft measurement, not necessarily the true mean draft.
