Mooring Snubber

[dartmoor]

Hi, I have a chain swinging mooring in quite a windy spot. Basically I attach the pick up buoy (which is attached to the chain by rope) to a deck cleat, and the chain has a shackle on it which I attach to a hook on the low down on the bow of the boat. So the boat always feels safe whatever is thrown at it. But, the chain I am sure creates quite a force on the hook on the boat. My boat is a Voyager 14 - so not big. I was wondering whether you can use rubber mooring snubber with chain? All the pictures show the the rubber type snubbers with rope?

I don't think you would get chain through the snubber's holes unless it was somewhat oversize, though you might like to experiment. You could put some line through a snubber and attach it alongside the chain, with a bight in the chain.

How about shackling each end of the snubber to the chain, with a bit more chain in between than the unstretched length of the snubber?

Although I'm not convinced it's necessary - surely the weight of a heavy chain on such a small boat provides plenty of damping already?

Thanks - I'll try that.

How about these, friend has them and swears by them. Might be easier to thread the chain than the usual types.

The " pin" is removable as shown here which is why they can be fitted without having to thread the end of the line or chain.

Why not use a length of stretchy nylon as main strop with the chain as backup?

Been doing this for 10 years, on a ten meter boat. I need to keep my rising chain taught to keep boat in centre of a channel. I have replaced the snubber once, it broke after two years, in the centre section which has the largest diameter so I think it may have been a fault. The other has some reduction on the loops at each end but still serviceable. I use shackles to attach to chain but need to change these about every three years.

using rope, you can use a small bumper and wrap several coils around it and out the other end hole.

An effective and cheap way to achieve robust 'snubbing' on your chain is to secure a small tyre - I have a couple of free small aircraft nosewheel tyres - on the chain by making 3 or 4 winds of chain around the tyre body. That works, and is close to indestructible.

Golf cart or other very small tyres, worn out, are free for the asking.

That was my first thought as well, but in a gale, a gust will possibly mean all the slack is taken up so a snubber should reduce the shock. Its something I need to consider for next winter but will need something suitable for an 11m 10tonner. The type based on a stainless spring look more upto the job than the rubber ones.

Problem with the springs is that they can do a lot of damage to your topsides.

You can run chain inside a pushbike inner tube which makes it nice and user friendly. It is still possible to attach a rubber compensator in a bight, with a bit of improvisation.

I have never had one of those black rubber willies break. They tend to give warning of failure by showing wear where the rope rubs.

I can imagine a broken willie is no laughing matter, but good point about the spring chewing up the paintwork.
