What grade or higher chain and steamboat jacks shall be used to secure buoys and deck cages?

• A. Grade 5
• B. Grade 7
• C. Grade 8
• D. Grade 10

Answer: (B)

When securing buoys and deck cages, the hardware must meet a minimum strength to safely handle the loads from wind, current, and vessel movement. Chain and steamboat jacks are rated by grade, which reflects their minimum breaking strength. The required minimum for this task is Grade seven, meaning Grade seven or any higher grade is acceptable. This grade provides enough strength to prevent failure under normal operational conditions, ensuring the buoy or deck cage remains secured. Choosing a lower grade would risk breaking under load, while opting for a higher grade is acceptable if conditions demand more strength. Always pair the chain and jacks with compatible hardware rated at the same or higher strength to avoid weak points in the rig.
