What is the recommended ship's velocity when mooring a vessel?

• A. 0.5 ft a sec
• B. 2.0 ft a sec
• C. 1.5 ft a sec
• D. 1.0 ft a sec

Answer: (C)

Controlling speed during mooring is about minimizing shock loads on the lines while keeping the crew enough time to respond and handle lines safely. Moving at about 1.5 feet per second provides a steady, predictable approach that keeps fenders in the right position and allows lines to be snubbed smoothly without sudden jolts. That pace translates to roughly 0.46 meters per second, or about 0.9 knots—slow enough to stay in control in close quarters but fast enough to prevent drift from wind or current. Going faster would increase dynamic loads on mooring lines and fenders, raising the risk of damage or loss of control, while moving too slowly can let currents or winds push the vessel out of alignment or delay the mooring process. So, 1.5 feet per second is the recommended speed because it achieves a safe, controlled approach suitable for mooring operations.
