Shark Byte


Shark Byte is the first synthetic rope ever designed from the ground up to resist fish-bite damage. Shark Byte's 12 individual strands are a composite of copolymer olefins mixed randomly with Vectran™ LCP (Liquid Crystal Polymer). Yale's theory is that by spreading the high modulus Vectran fiber over a larger-than-required cross-sectional area to achieve a given strength and mixing it with a "tough to cut" lower modulus fiber, greater resistance to bite damamge can be achieved. Shark Byte 8 is an 8-Plait construction that is a composite of copolymer olefins and polyester.

Yale's Shark Byte 12 has successfully and extensively replaced wire on DART buoys, making them more easily serviced. Shark Byte is easy to splice, entirely torque free, supple even in sub-zero temperatures, and most importantly, hard to cut, if you are a shark and using your teeth. Typically residual strength of an attacked rope is in excess of 40% of a new rope's strength*.

Shark Byte 8 is available as an 8-Plait construction to match existing mooring line systems. This product was designed to have a higher specific gravity to ensure that it is a sinking rope, and it was designed to be a less-expensive alternative to Shark Byte 12 strand.

This product is neutrally buoyant. The theoretical specific gravity of the combined fibers is greater than water, i.e. > 1.0, interstitially trapped air may affect the actual value for buoyancy.
