Nautical Term: CALM

Definition of CALM

Catenary Anchor Leg Mooring refers to a specific type of mooring system for vessels. This system uses a heavy anchor with a long chain attached to it. The other end of the chain is connected to a catenary, which is a flexible curve that distributes the weight of the chain and the vessel evenly. This system allows vessels to be moored in a calm and secure manner, even in rough seas.

For example, during a storm, the captain of a large cargo ship decides to seek refuge in a nearby calm harbor. The crew quickly prepares the ship for mooring using the catenary anchor leg mooring system. The heavy anchor is lowered into the deep waters of the harbor, while the long chain is wound in and connected to the catenary. The crew then skillfully maneuver the ship into position, while the captain keeps a careful watch on the stormy seas outside the harbor. Once the ship is securely moored using the catenary anchor leg mooring system, the crew can finally relax and take a well-deserved break from the stormy seas outside the calm harbor.
