You'll find a couple of Nigel's tow-line systems in the stores, produced by Extrasport. One is a stand-alone system, the other a retro-fit accessory to PFD's, such as the Nigel Foster Explorer 2 by Point65, or the earlier Extrasport Retroglide Sabre, which have belt loops and a storage pocket that will accommodate the tow-line.
Both these tow systems use webbing in place of line. Webbing can be quickly flat-coiled for stowage and uncoils cleanly and rapidly for use.
The stand-alone system, the Extrasport NF 2.0, is lightweight, floats and the webbing stows easily into its mesh storage pouch. It s a waist-tow system. Nigel's ingenious "easy-tracking" system allows the tow-point to run from hip to hip without pulling the release buckle from its position at the front, making it easier to locate whenever a rapid release is needed.
The integrated tow-system, the Extrasport NF 1.5, quick-releases from either of two hip-located release tabs. You can use either left or right hand to release.
The webbing flat-coils into a pfd pocket, so the system is always at the ready whenever the pfd is worn.
