A cable fairing is a structure attached to a towed cable designed to streamline the flow around the cable, primarily in marine environments.
Cables are faired primarily for two reasons: to reduce normal drag and thus achieve more depth for a given cable scope and speed; and to eliminate cable vibration caused by vortex shedding, commonly known as cable strum.
?Hairy Fairing? will decrease the hydrodynamic drag by 40 ? 60%. The ?Hairy fairing? can be incorporated in a short length of cable, or for the entire length of cable.
The fairing material can be polyester, polyamide or copolymer in construction.
The advantages include;
Cables are unaffected by winches or sheaving
