I'm using an 8kg grapnel. I'm yet to test it but I think it should be fine for my boat (quite light). Bought it becasue it folds up so small. Had one on my 4.1m (2kg) and it held really well (had ten meters of chain attached though)

grapnels are crap crap crap on sandy bottom, you could use a 2 or 3kg bruce instead of a 8kg grapnell and i am sure it would hold loads better. Bob and i used grapnells and we just could not hold, i got a bruce same as alices as that proved itself when we both anchored to it, bob is getting a new anchor as well i beleive

bruces are nice cos they dont have those moving bits that pinch your fingers

just our experience over the last two weeks

I haven't used it yet but I looked at the anchor on mine and thought it was a bit small, its a Danforth type not sure of the weight but prob about 8-10kg. Then I saw a similar sized anchor on a 12 tonne Halmatic launch and figured it should be OK for a 1/2 ton rib

On mine it is just the right shape to perch securely in the compartment in the bow sitting on top of the heap of chain and rope (think there is about 50m of rope).

Can I hijack the thread slightly; how often do folks think you should change the rope on the anchor? Deterioration of the chain is fairly obvious but rope....? It's probably the original one so about 6-7 years old.

Sunlight is prob the worst killer of rope. If the rope looks fine with no nasty abrasions etc and hasn't been kept in the sun you should be fine.

Know what you mean about OTT mooring tackle. I have 2x50m lengths of 16mm rope - that's over 300' in real money - plus about 20' of stupidly heavy chain and a 14lb danforth. Plenty of room for it all.

For day to day stuff I have a big folding grapnel - yet to try it though. I know they are crap in sand but they are better than most in foul ground.

I got a 5kg bruce last week and used it at the weekend on the North coast. it held me and Ian Parkes well. (That's not just Ian - his boat as well) So much better than grapnells. and it fitted in the anchor hold...although there's no room for my spare fuel cans anymore - Ooops, I don't seem to have any spare fuel cans anymore!

which anchor

My Personal choice after trying most of the anchors types over the years is a 5kg bruce which is rated as a storm anchor for powerboat upto 25" but a CQR or danforth are probably almost as good ( my view that is), i would use 10m chain, as the the rule of thumb of 1 boat length of chain then rope, is a minimum in my view!!

then make sure that your total chain & rope is at least 6 times depth, preferably 7 times if possible, really depends on how much you want to make sure you boat doesnt move too far from where you left it.

As to the folding grapnel type anchor, they make a good mud weight if unopened and they do pack up neatly on a boat......yep thats the only positives i can think of for them

I have a 7.5 KG Bruce with about 30m of chain and 50 odd m of line.
Basically the biggest anchor I could get in the locker and you never know what might happen.
I also have a pickup bouy on the end of it incase I have to let it go because of a snag etc so we can retrieve it later.
We also have a 5kg CQR thats going to be rigged as a spare / lunch pick.

A quick point here about the theoretical "scope" (ie how much anchor line to put out)....

If you are anchoring amongst other boats, put out a similar scope to everyone else, regardless of the theoretical calculation. If you put out much more, when the tide turns you'll swing around in a greater arc to everyone else and very likely either hit the other boats or tangle your lines.
