🔍 Key Concepts

• Look at how line C runs between the ship and the dock compared with the other lines. • Recall that spring lines run generally fore-and-aft along the pier to prevent the vessel from moving ahead or astern. • Remember that breast lines run more or less at a right angle from the vessel to the dock to control how far the ship lies off the pier.

💭 Think About

• Is line C mostly parallel to the length of the pier, or does it lead out from the ship toward the dock at a near right angle? • Which type of line (bow/stern, spring, breast) is primarily meant to stop the ship from moving closer to or farther from the pier rather than forward or backward along it? • Compare line C with D and E: which of these look like they are stopping fore‑and‑aft movement, and which is mainly checking sideways movement?

✅ Before You Answer

• Verify whether line C leads nearly perpendicular from the vessel to the dock (athwartships) or diagonally along the pier. • Check which answer choice names a line whose main job is to hold the vessel in toward or off the dock, not to keep it from moving ahead/astern. • Eliminate any option that describes a line type that clearly runs fore‑and‑aft along the length of the ship and pier in the illustration.
