TCF-20 (Z-Track)
  • Drag and Noise Reduction
  • One Piece Construction
  • Excellent Abrasion, Environmental and Chemical Properties
  • Excellent Flexibility
  • Moderate Seas, Up to 5 Knots

The TCF-20 Towed Cable Fairing is designed to significantly reduce the vibration, acoustic noise, and drag created by water movement across a towed-fish cable. The single-row fin design improves the hydrodynamic flow characteristics across the cable, reducing vibration and "strumming" because each independent, flexible fin is free to assume the most favorable flow orientation.

In addition, where multiple cables are used, the fairing bundles them all into a single, streamlined package for easier handling and even greater drag reduction. The TCF-20 features a 20-mil wall jacket with the Z-Track closure system and is intended for use under moderate sea conditions and at tow speeds up to 5 knots. The material offers good wear resistance, high tear strength, flexibility, and oil and hydrocarbon resistance, in addition to being impervious to saltwater.
