Tether with 3 premium aluminium safety hooks

Ref: 67494

In the case of a harness tether, whose advice could be more relevant than the national search and rescue squads ? So Plastimo was proud and thrilled when the French National Lifeboat & Lifeguard Society (SNSM) asked our R & D teams to co-develop and manufacture the tether that rescue teams will use in their mission : a technical and really innovative product stemmed from this cooperation. This tether is now available to all sailors.

• One-piece tether : while tethers are traditionally constructed from two webbing pieces, the Plastimo-SNSM model is built from one single webbing strap. This exclusive design provides optimum safety and added performance feature.

• Flexible tether includes a sewn-in retro-reflective thread to optimize visibility at night.

• Double safety aluminum hooks with anti-slip-grip treatment : a yellow hook secured to the harness and two orange hooks connected to the jackline or fixed point on the boat. Orange hooks feature an additional protection against rubbing and chafing through a hard-anodizing process.

• One short straight strand 100 cm, one long elastic strand 110-175 cm.

• Two strain indicators : when the tether is submitted to a heavy load, the strain indicator exposes a label indicating that the tether should be replaced.

• Supplied in a mesh bag.

• Breaking strain : 1650 kg.

• RORC-RSO 2018 compliant

• Weight : 570 g.

Plastimo tips & tricks

A tether is the indispensable accessory which makes an inflatable lifejacket a fully featured safety equipment. Provided of course, that you have originally selected a lifejacket with integrated harness : the only version providing the adequate resistance and featuring a stainless steel triangle to secure the tether.

When using a harness in conjunction with a tether, it is essential to check that both the harness and the tether are designed to the same standard, and specifically to the same breaking strain level.
The breaking strain is defined by the original standard, but also by the age of the harness or tether : the ageing and general condition of the webbing impacts negatively its level of performance.

Essential features

• Number of lines : a double tether has 2 lines or strands. It enables you to remain clipped as you move about the deck.

• Number of hooks : there is not systematically a hook at both ends ; the tether can be attached to the harness via a webbing loop.

• Length of lines : standard length is 2 m. In the case of a double tether, the 2nd line is reduced to 1 m so that you can clip yourself on a shorter length. The very principle of a harness is to prevent a man falling overboard and being dragged ; one must therefore be clipped on a short length, as often as possible.  

• Elasticity : the tether stretches out when needed and contracts when not under tension, which contributes to a greater freedom of movement and improved safety, as it is kept short and tidy to prevent accidental snagging. The elastic tether is the obvious choice for yachtsmen who wear their harness regularly.
