Frequently Asked Questions

What is a heaving line used for?

A heaving line is used to carry a heavier mooring rope or messenger line from a vessel to shore or between vessels. It is thrown manually and should be light, strong, and easy to handle.

What is the advantage of nylon heaving lines over polypropylene?

Nylon offers higher tensile strength, better abrasion resistance, and lower stretch under load compared to polypropylene. This makes it more durable for heavy marine use, though polypropylene is naturally buoyant. Nylon lines are also more resistant to UV degradation in many cases.

How do I choose the correct length and diameter for a heaving line?

The choice depends on the vessel size and mooring distance. Common lengths range from 25 to 100 meters, with diameters between 6 and 12 mm. For offshore use, select a larger diameter with higher breaking strength. Consider port requirements and deck layout.

How should I care for and store my nylon heaving lines?

Keep the lines clean, dry, and free from chemicals. Rinse with fresh water after exposure to salt, allow to dry, and store in a cool, dry area away from direct sunlight. Inspect regularly for wear, cuts, or abrasion and replace if damage is found.
