Anchor bridles (and snubbers) are lengths of nylon line attached to a chain hook. They are used when anchored to create a direct link between an all-chain anchor rode and strong points on your boat - bypassing the windlass.
Bridles not only relieve wind and wave shock loads on the windlass, but also provide shock absorption — which helps keep the anchor in place on the seabed.
Features of the Mantus Anchor Bridle
• Designed to absorb shock loads on the anchor rode generated by waves and wind gusts
• Helps protect deck gear from shock loads
• Helps protect anchor from shock loads which could dislodge it
• Takes anchoring loads off the windlass - which is not designed to withstand heavy loads or shock loading
• Strong and durable
• Large spliced eyes fit virtually all deck cleats, hawse cleats and bitts
• Super secure 8 tuck eye splices
• Heavy duty chafe protection extends for five feet on each leg and at the thimble end
• Uses heavy duty 316L stainless steel shackles and thimbles rated to be as strong as the largest high test chain that matches the system
• Mantus Chain Hook is sized for your anchor chain and is designed to be stronger than the (high test) chain
• Included high-load carabiner can replace the chain hook for convenience when using the bridle for attaching to a mooring buoy
Heavy on the technical side...
Anchor bridles and snubbers are lengths of stretchy nylon line attached to a chain hook. They are used when anchored to create a direct link between your all-chain anchor rode and strong points on your boat - bypassing the windlass.
Snubbers (one line) and bridles (two lines) perform two important functions:
1) When at anchor, the hook on the bridle or snubber is attached to the chain while the other end(s) attach to your mooring cleats at the bow.
This allows you to ease the windlass, creating some slack in the chain. The result is that the load of the boat comes on your mooring cleats instead of the anchor windlass drive shaft, which is not designed to withstand heavy loads or the shock loads on the chain created by wind and waves. (The windlass is designed for steady loads of approximately the weight of your chain plus anchor - not the high force of the boat against the anchor in high winds.)
2) The fact that the bridle is made with 3-strand nylon rope introduces stretch (shock absorbancy) into the system which augments the caternary effect of the anchor chain in light weather.
This stretch relieves some of the shock load on both your mooring cleats, as well as the anchor's purchase on the seabed, when the boat fetches up due to waves or wind gusts - helping everything to stay in place.
In severe conditions, the chain may be stretched tight, providing no shock-absorbing function at all, leaving only the bridle to provide stress relief.
