Abstract
Abstract A yarn or fiber is incorporated into the jacket of a long suspended small ameter cable for reducing low velocity current cable strumming in water. The yarn or fiber comprises at least one-quarter of the strands of a braided cable. A nap or mossy cable effect is produced when the jacket is brushed.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
88 words
An antistrumming cable comprising: conducting means for providing a path for electrical signals; and antistrumming means enclosing said conducting means and constituting the outermost surface of said cable, said antistrumming means comprising a braided jacket having at least 25 percent of the jacket made of polyester material fibers, said polyester material fibers being substantially uniformly spaced over the entire outer surface of said braided jacket said fibers having been brushed to produce a nap which provides a mossy effect that is adapted to reduce vortex shedding in seawater.
