Swinging mooring.

Nyarla · 01 April 2005, 11:26

Hi folks, question for you.
I have just obtained use of a swinging mooring, very low water drying, at Northqueensferry.
It`s a buried JCB wheel and tyre with a very heavy chain on it. I am fitting a large buoy and swivel to the chain and intent to hopefully leave my rib on the mooring over long weekends.
Now the question.
Is there a self locking shackle or clip I can use to hook up to the swivel that has a very low to zero chance of coming adrift from my painter. I am not happy with my skill with bits of rope so wish to be able to clip on without using any knots.
If I have to I will use a shackle but that means mousing it every time.
The painter at the moment has a large Carbine clip on it but I don`t think this is secure enough.
Any Idea`s.

You could always try a locking Karabiner, some lock using springs, some lock by you tightening a sheath around the shaft.

Have a look at the screwgate karabiners here , especially the Petzl - Am'D Ball Lock, which looks as though it would be very hard to accidently open.

You might want to think about security and the chance of the painter chaffing through.

we use a 6 foot length of chain fixed to the underside of the buoy with a moused shackle. The chain is inside plastic tube to protect the boat and the end of the chain is padlocked to the deck fitting in the rib, a second side chain is fixed to the bow fitting with a Karabiner with a spring sleave to keep it shut.

This gives security with two fixing points, but the load is on the bow fitting not a chain laying on the tube.

Same here

except that you must take the chain from above the swivel or you will wind the chain around the buoy

I haven’t found an SS Karabiner with a sprung sleave yet so I use two normal ones in opposite directions

Please don't mix stainless steel and steel chain or you will get electrolytic corrosion. Also when you are putting on the shackles there is a way to put them on so they tighten when they nag not loosen, but you should still mouse the shackles.
If you are going to buy a buoy avoid the ones with a metal rod up the centre with an inflatable collar, I have seen the rods break and the collars shred.
If you go with the type where you pass the chain up the center and it had a plate to hold it in place, put a big knot in the chain so if the plate fails the chain won't drop.
I keep my 7.4 on a fore & aft mooring when afloat which has a main load baring line connected to the eye with a quick link and a second safety line
loose over tubes made off to the cleat.
This was on the YBW site and quite of a few of them seem to lay their own.

If you are going to use karabiners don't use the alloy climbing ones - not too good in salt water when attached to a steel chain!!!

Steel ones are a lot tougher

Most climbing places don't stock steel because it is too heavy.

Unless I was sitting on the waterside with a sniper rifle, I wouldn't leave my rib out in the middle of the water.

A word of caution - make sure that your insurance covers you when on a mooring. A local Ribster across here is having a major battle to get his insurers to pay up for damage sustained to his Rib when it broke free from a swinging mooring last year.

Andy, I heard that the last guy you shot at sheltered in this iron bunker...

I must have been in a good mood that day

No, the french are very proud of their d-day defences!

Try the safety harness carabiners, they are designed for marine use, and will NOT come undone unless both edges are pressed (effectivly grasping the whole carabiner..) Just pressing the release mechanism wont open it, or just pushing against the clip that falls back wont open them, you have to do both at once... and they wont go rusty...

screw lock ones might get salt buildup in them, and refuse to open, and will take a while to open anyway, any other just dont seem safe/reliable with rope rubbing up against the carabiner..
As others have said, dont use climbing gear, they will just rust into pieces.. even galvanised things have gone rusty over here, its horrid...

Dad has stuck his away already again, so no pic, sorry!

Cheers for all the good info and links everybody.
Now if someone will come and wade out in the bottomless stinking mud to attach my riser chain etc that would be even better

Thanks again and anyone up in the Firth of Forth anytime give me a shout.

You take care in that mud. You could be there for a very long time.

Mr-d · 02 April 2005, 11:40

Go round the buoy with your boat and a length of rope, lay it along to the shore, and then get one of them plastic overalls and bellyslide! could even get people dragging you around by pulling the rope, fantastic!

I kept my P22 in Strangford Lough on a swinging mooring for years with no problem sitting in a 4 knot tide.I used a railway wheel with a length of 20ft steamer/ground chain.
I then attached 30ft of galvanised 1/4" riser chain which rose to the mooring buoy.The riser was adjusted so that on high water springs it only lifted the last link of the steamer/ground chain which meant there was no real drag put on the wheel.
The mooring buoy was one similar to the yellow buoys used by the HIES for visitors in Scotland.This meant that the riser chain passed up through the mooring buoy without a break and was attached to a large swivel which was in turn shackled to a small piece of lighter chain.This was then attached to the 'D' ring of the RIB with the biggest marine grade snap shackle I could find.
Worked well in all weathers and sea conditions.
