Which statement about the deck line is TRUE?

Correct Answer: Option C — A vessel with wooden planks on a steel deck will have the deck line marked at the intersection of the upper line of the wood sheathing with the side shell.

Load Line regulations (46 CFR Part 42) specify that if a vessel has a wood deck sheathing, the deck line is marked at the intersection of the upper surface of the wood sheathing with the side shell. This ensures the freeboard calculation accounts for the actual effective depth of the hull.
