What is the purpose of lifelines on a vessel?

Lifelines on a vessel serve a crucial safety function by providing safety railings that help prevent crew members from accidentally falling overboard. They are typically made of strong, durable materials and are strategically placed around the perimeter of decks to ensure that everyone onboard has a protective barrier while moving around the ship. This design supports overall safety protocols, especially in rough seas or when performing tasks that may require leaning over the side of the vessel.

In contrast, the other options do not accurately describe the primary function of lifelines. Entertainment for the crew is not relevant to their design or purpose. While lifelines might play a minor role in stabilizing activities during anchoring procedures, their core function is unrelated to that specific task. Lastly, lifelines are not used for storing safety equipment; that function is fulfilled by designated storage areas onboard. Thus, the primary purpose remains centered on ensuring the safety of individuals aboard the vessel.
