Your vessel is floating in water of density 1.010. The fresh water allowance is 8 inches. How far below her marks may she be loaded so as to float at her mark in saltwater of density 1.025?

Correct Answer: Option D — 4.8 inches

Calculate dockwater density correction using standard load line principles. The displacement difference between fresh water and the dock density (1.010) allows the vessel to load deeper than salt water marks. Using the 8-inch FWA, the allowable submergence is computed as 4.8 inches.
