🔍 Key Concepts

• Effect of current and wind on a mooring evolution when landing port side to with vessels ahead and astern • Best tug position for lateral control (pushing on or holding off) versus fore‑and‑aft control when space is restricted • How a tug made up at the bow, quarter, stern, or waist changes the pivot point and control of the ship’s heading

💭 Think About

• In a slight head current, what is your ship already doing in terms of speed and control, and what extra help do you most need from the tug as you go alongside? • With a light wind blowing you off the dock and limited room ahead and astern, do you most need the tug to control your ends (bow or stern) or to push the whole ship bodily sideways? • Which tug position gives you the safest way to come alongside slowly while still being able to stop the ship from sheering ahead into the vessel in front or astern into the vessel behind?

✅ Before You Answer

• Verify which location gives the best leverage on the ship’s heading while still allowing you to control how hard you land alongside in a current and light offshore wind • Check which option is least likely to cause the bow or stern to swing uncontrollably toward the other berthed vessels if the tug pushes or pulls • Consider which position is commonly used for controlled, gentle landings port side to when there is limited space fore and aft and only one tug available
