Heaving Line Rope – Lightweight Throwing Line for Mooring & Marine Use
Throw, Catch, Secure – Essential Heaving Line for Every Vessel
Our Heaving Line Rope is a lightweight, floating throwing line designed for ship-to-shore and vessel-to-vessel line transfer. Used by mariners worldwide, this essential deck tool allows crew to send a messenger line ashore, which is then used to pull heavier mooring lines to the dock. Made from buoyant polypropylene, it floats for easy retrieval and resists moisture, rot, and marine growth.
Key Features:
✔ Floating Design – Polypropylene material stays on water surface for easy pickup
✔ Lightweight & Flexible – Easy to coil and throw long distances
✔ High Visibility – Bright orange, yellow, or white for clear sighting
✔ Pre-Spliced Eye (Optional) – Ready-attached loop for monkey fist or messenger line
✔ Knot-Friendly – Holds knots securely without slipping
✔ UV & Saltwater Resistant – Won’t rot or degrade in marine environments
