Product Overview

WEST MARINE ISAF/ISO Specification 12401 Single Safety Tether

Elastic single tether has a 6' leg that extends from 41" to 72". This tether meets all ORC Special Regulation requirements for strength, design and features for sailboat racing. It incorporates a lightweight aluminum double-action safety hook, built-in stress indicator.


  • Includes bright overload indicator flags embedded in the stitching that are exposed when the tether is stressed to the point of needing replacement (about 900lb. of force triggers the flag)
  • The boat-end aluminum safety hooks have easy-to-use double-action gates that automatically lock closed, so they won’t accidentally release from attachment points
  • Double-action gates are extremely easy to open in one ergonomic movement without pinching your hands
  • Internal elastic located inside the webbing cover retracts when not under load, staying out of the way
  • Non-magnetic, stainless steel auto-locking carabiner at chest end connects securely to the harness
