Anchor, dock and tow lines see some pretty rough action, especially in choppy water. And whatever deck hardware they're tied to shares in the strainas does everyone on board. With Shockles from Davis Instruments, all this jarring is cushioned. The innovative devices minimize stress and chafe on lines and absorb damaging shock loads, providing a more comfortable and safer boating experience.
Patented Shockles are available in three models, each with a specific purpose in mind. All have UV-resistant 1,140kg test nylon webbing covering a 1,590kg test marine grade elastomer and internal line limiter. With this, tension increases progressively to counter loads placed on it, whether gentle or violent, as the device stretches to its maximum length.
Available in black or blue, Shockles LineSnubber is 71cm L overall in a relaxed state and stretches to 91cm. Two 98mm 316 stainless steel captive carabiners are sewn into the device, each has a safe working load of 544kg.
Similar to LineSnubber, AnchorSnubber has two 77mm stainless steel Key Pin Halyard Shackles, each with a safe working load of 680kg. They'll run though most bow rollers and handle chain twist better than a carabiner.
At 45cm, DockShockle is ideal for inland waters and lighter boats up to 12m. It comes with a pair of carabiners and a Mini-LineGrabber for easy attachment to double braid or three-strand line up to 19mm.
Using a Shockle is easy. While extremely strong, it needs to be rigged in line with the rope or chain so it never bears the full load alone; most cordage has a higher safe working load than a Shockle. For a LineSnubber or AnchorSnubber, provide 15cm30cm of slack between the attachment loops to a maximum of 30cm as loads increase. For a DockShockle, the ideal working slack is 8cm15cm.
