WEST MARINE
ISAF-Specification Safety Tethers

Meeting all ISAF (International Sailing Federation) requirements for strength, design and features for sailboat racing, these safety tethers incorporate a lightweight aluminum double-action safety hook, built-in stress indicator and welded O-ring for improved security offshore, whether racing or cruising. The stress indicator features a bright overload flag that is exposed when the tether is stressed to the point of needing replacement (about 900lb. of force triggers the flag).

The boat-end aluminum safety hook has an easy-to-use double-action gate that automatically locks closed, so it won’t accidentally release from attachment points. Yet, it’s extremely easy to open in one ergonomic movement without pinching your hands. Internal elastic retracts when not under load, staying out of the way. Nonmagnetic, stainless-steel snap shackle at chest releases from the harness under load.

I purchased the dual length tether and found that it was useful to clip one tether while disconnecting the other, thus allowing one to move about the boat past any obstructions and always be clipped in. I just clip them to the safety harness ring on my Offshore PFD when not in use and they generally stay out of the way.

The clip that attaches to the jackline is awesome. The clip that attaches to your vest can be detached almost too easily with a quick pull of the lanyard. I worried that the lanyard could easily get hooked on something and detach the teacher at the wrong time. Otherwise, great craftmanship, loved the teacher.

        Sailing offshore in rough conditions requires a tether for safety. This product does a good job in keeping me on the boat when conditions are rough and I get bounced around.

                  This tether is AWESOME. I love the heavy duty carribiners attached to each tether. The tether is meant to take a severe punishing and survive. The clips are aluminum so they won't corrode. This also makes them light.
                  It's so easy to snap in and out of these.

                  Comments about ISAF-Specification Safety Tethers:

                  Really like the terminal clips, better than average carabiners. Clip easily to jacklines or whatever, and release as easily when desired. Wish it had the stack of 3 wooden beads on the harness-end snapshackle pendant like other models I've used, as this would make getting free in dire emergencies easier.

                      I bought this to go along with my Mustang AutoInflate PFD with Safety Harness.

                      It is well made, easy to use, and unobtrusive. The Double Hook makes it easier and safer to use and although I have not had to test its ability it gives added confidence that even if I do slip, that I will not fall overboard.
