Which mooring line checks forward motion of a vessel at a pier?

🔍 Key Concepts

• Mooring line names are based on both where they are attached (bow or stern) and what direction of movement they control (fore-and-aft vs in-and-out from the pier). • A line that checks forward motion will lead in the opposite direction of that motion, i.e., it will run aft if the ship is trying to move ahead. • Understand the difference between breast lines (mostly control distance from the pier) and spring lines (mostly control fore-and-aft movement).

💭 Think About

• If the ship tends to move ahead (forward), which direction must the controlling line lead along the pier to resist that motion? • Look at each option and picture where it is attached on the ship (bow or stern) and which way it is led (forward or aft) relative to the pier. • Which type of line is primarily responsible for preventing the ship from surging forward or aft along the dock, as opposed to simply holding it in toward the dock?

✅ Before You Answer

• Be sure you know the difference between bow line vs forward bow line vs stern line vs stern breast line. • Confirm which lines are breast lines (mostly at right angles to the pier) and which are springs (running fore-and-aft along the pier). • Before choosing, mentally sketch the ship at a pier and draw each named line to see which one actually resists forward motion along the pier.
