What is the minimum number of turns of towline that should always be kept on the reel?

The minimum number of turns of towline that should always be kept on the reel is five. This is important for several reasons.

Having a minimum of five turns ensures that there is enough friction and security on the reel to prevent the line from slipping off during operations, especially in situations where there may be sudden tension or jerking forces. It provides a secure grip, ensuring that the line remains coiled even if it is subjected to movement or if the vessel encounters waves or swells. Additionally, more turns allow for a better distribution of strain, which enhances the durability of the towline and minimizes the risk of it getting damaged during towing operations.

Keeping fewer than five turns could lead to unsafe conditions where the line might unravel or become tangled, which could compromise both the towing operation and the safety of personnel involved. Therefore, maintaining at least five turns is a standard practice in marine operations to ensure both safety and effectiveness during towing tasks.
