Question 1811 Deck Safety

The correct answer is C) draft. The draft of a vessel refers to the distance between the bottom of the hull and the waterline. This is a critical measurement for a vessel, as it determines how deep the vessel can safely operate in the water without running aground or experiencing stability issues. The other options are incorrect because: A) Reserve buoyancy refers to the additional buoyancy a vessel has above the waterline. B) Tonnage is a measure of a vessel's size, not its depth in the water. D) Freeboard is the distance between the waterline and the main deck of the vessel, not the bottom of the hull.
