Mooring lines constructed of different material have variable elasticity. Which of the following is true concerning their combined use for mooring a vessel?

Correct Answer: Option B — lines of different elasticity should never be used together in the same direction

Lines with disparate elasticity, such as steel wire and nylon, react entirely differently under dynamic loads. Pairing them in the same direction causes the more elastic line to stretch excessively while the rigid line takes the entire shock load, risking failure.
