"Reach, Throw, Row, Go." If you know what this means then the Water Rescue Rope is what you're looking for
Water Rescue Rope is a spliceable floating rope for use in swift-water rescue applications. The rope has a durable nylon sheath that protects the braided multifilament polypropylene (MFP) core from damaging UV rays. This combination results in a strong product that floats just under the surface of the water.
