I have always used the folding grapnel anchors because they are easy to stow and seem to work well enough. Normally anchoring a RIB is a short term measure, so choice of gear is not quite as critical as for say a yacht that will regularly be anchoring overnight.

My setup was a 5Kg anchor with ten metres of chain and 30 metres of 10mm climbing rope that I bought cheaply at the Southampton Boat Show. This was easily sufficient for a 7.5 metre RIB and is easy to stow and deploy.

I don't coil the rope, but make it into a "daisy chain" (or caver's plait, or chain sennit) which is very easy to pay out in an emergency without tangling.

Places like Jimmy Green Marine will make up complete anchor warps including splicing, but it's not difficult to do. Splicing octoplait to chain is easier than tying your shoe laces!

OK, I'll rephrase that.

Splicing octoplait to chain is even easier than tying your shoe laces!

Marvellous as it I wouldn't recomend using velcro for that all important chain/rope join!

I'm not sure that I'd be all that keen on your all chain solution either. It would be very heavy to haul up in any real depth of water. You may just be more macho than me though

Ah, but it's not as bad as you might think because it's lighter when it's under water.

But I agree. I wouldn't want to haul up a 100mtrs.

Erm...

...so just to get it straight in my head...

Because it is the physical size of the anchor that's important, if I had a 10kg steel anchor, I could use a lighter one of the same size in Ali to do the same job.

I should use as much chain as I can, but probably at least 5 - 10 metres, the rest (20 - 25 metres) being nylon rope.

Is that right?

Oh - and although I am very good at shoelaces, and therefore ought to be able to splice my own anchor/chain etc, does anyone have instructions/pics on how to do it?

Slip ons!

Actually the octoplait to chain splice is much easier than it looks in the diagram. When I first did one I had to go back to the book to check because I couldn't believe it was really that simple! The Octoplait eye splice looks a little more involved though . . .

I personaly would go larger on on the Bruce and have more chain.
I have a 7.5 Bruce, 15-20m chain and 40 odd meters of octiplait for my 7.4 Redbay and I was thinking of going to a 10Kg.
I would have thought that Cyanide would have needed more and the anchor is there for than a lunch pick ( I 'm looking at a second one for that I can lift ) IMHO its there for the last resort.

If you can splice then ocitplait is possible but label every core and take your time and check as you go - its very annoying to find a fault at the begining when you have finished on the eye splices

If I can help drop me a pm
James
