How many heaving lines are required to be laid out at each line handling station?

Two heaving lines are required to be laid out at each line handling station for effective safety and operational efficiency. Having a pair of heaving lines ensures redundancy; if one line fails or becomes unusable, the other is readily available to complete tasks like tying up or maneuvering lines. This practice also enhances safety, as crew members can utilize a backup line in case of emergency or unexpected situations.

Moreover, laying out two heaving lines allows for simultaneous handling and enhances teamwork among personnel. It encourages a quicker response during line handling operations, which is essential in maintaining control of vessels and reducing the risk of accidents. Therefore, having two heaving lines is a critical aspect of line handling procedures in maritime operations.
