Deck General USCG Question #5424 (Set 169)

Why should you preload a mooring system above your pre-calculated operating mooring tensions?

Official USCG Answer & Rule Citation

Correct Answer: Option C — This serves as a benchmark for increasing tensions in rough weather.

Preloading mooring systems above calculated operating loads seats the anchors, embeds components, and tests structural integrity. This provides a safe, proven baseline tension benchmark, ensuring the vessel will not unexpectedly slip or drag its moorings when severe environmental weather forces develop.
