Given the same water depth and line tension, the length of the ground cable of a 90 pound/foot mooring chain compared to the length of the ground cable of a 19 pound/ft wire rope mooring line will be __________.

Correct Answer: Option D — longer

Heavier mooring chain requires a longer ground cable length to achieve the necessary catenary curve and resting weight on the ocean floor compared to lighter wire rope under identical water depth and tension parameters.
