Mooring lines are strong ropes or cables used to secure a boat or ship to a dock or pier. They help keep the vessel in place, preventing it from drifting due to wind or currents. These lines are typically made from durable materials like nylon or polyester, which can withstand harsh marine conditions. When mooring, several lines are often used, including bow lines, stern lines, and spring lines. Each type serves a specific purpose, ensuring the vessel is stable and secure. Properly managing mooring lines is essential for the safety of both the vessel and the surrounding area.
