When Water Is the Mission — Sterling WaterLine Water Rescue Rope

Out on the river, flood zone, or during ice rescue, your rope must float, perform, and keep you safe. The WaterLine rope was engineered specifically for the challenges of aquatic rescue — combining buoyancy, strength, and low stretch in one dependable line.

Designed for Water Rescue — Not a Compromise

• Floats even under load — Built with materials that maintain surface tension and visibility in swiftwater, flood, and rescue settings.
• Kernmantle construction — A braided sheath and internal core structure deliver strength without sacrificing buoyancy.
• Material blend for performance — Made with polypropylene (or core/sheath combinations depending on diameter) to optimize float and minimize water absorption.
• Multiple diameters available — Options include 5/16", 3/8", 7/16", and 1/2" to match mission requirements and throwline needs.
• Strong, low-stretch design — Each size carries a tested tensile strength rating (for example, the 7/16" version is rated at 4,406 lb) and delivers minimal elongation under load.
• Sold by the foot — Custom lengths are available and rope ends are included at no extra charge, giving you exactly what your operation demands.

Technical Snapshot

• Available diameters: 5/16", 3/8", 7/16", 1/2"
• Tensile strength (example: 7/16"): ~4,406 lbs
• Elongation: Low stretch under normal loads
• Weight / buoyancy: Optimized for float behavior
• Construction: Polypropylene core and/or sheath as required by each size
• Max continuous length: Up to 300 ft
• Color / tracer options: High-visibility appearances to aid in on-scene clarity

What Makes WaterLine a Rescue-Ready Rope?

• Better scene visibility — A floating rope remains on the surface where it’s easier to track and manage.
• Dual-purpose use — Suitable for throwlines, anchor back-ups, tether lines, water crossings, or any hybrid water/rope operation.
• Resistance in wet environments — Materials minimize drag, absorption, and degradation from exposure to water, UV, or ice.
• Flexible handling — Responds well to knots, hitches, and rigging without excessive stiffness or memory.
• Simple procurement — You order exactly what you need — no leftover tail, no surprise fees for cut ends.

Ideal Use Cases & Mission Profiles

• Swiftwater, flood, and ice rescue
• Shore-to-shore or bank-to-bank systems
• Tether lines, throwline support, or mid-line anchor runs
• Scenarios blending rope and water operations
• Departments that want one rope solution across water and land tasks
