MST II Mooring: wind and broadside current limits?

MST II Mooring: wind and broadside current limits?

• A. Up to 50 kt wind with 1 kt current
• B. Up to 64 kt wind with 2 kt current
• C. Up to 64 kt wind with 0 kt current
• D. Up to 40 kt wind with 2 kt current

Answer: (B)

The main idea is understanding the environmental envelope the MST II mooring is rated to handle. The system is designed to tolerate wind up to 64 knots and broadside current up to 2 knots. This combination represents the maximum conditions the mooring setup can safely resist, with the current adding lateral load to the lines and hardware just as wind does. Therefore, the highest permissible scenario is 64 knots of wind with 2 knots of broadside current, since both limits are reached together. The other options either reduce the wind or the current, or pair a high wind with a smaller current, which does not reflect the defined maximums for this setup.
