I use the "cable tie" method - has worked every time so far - just make sure you have plenty of spare cable ties on board.

Stuck anchor

Having dived the Peverill ledges many times I know how snaggy they are! Good lobster & crabs to be found tho, especially close to the sewer outfall!!! LOL
We use the cable-tie method on our anchors. Several strong ones attached & a good old tug will break the chain free which is now attached to the 'Wrong end' of the shaft. You will be pulling the anchor out in a backwards direction! Or if you want to involve more line & a buoy use the 'Trip' method? Home-made grapnel anchors that bend free is what we use to hook a wreck if there is a chance we could lose the shot-weight? Hope this helps?

I've got my spare anchor (a Bruce knock-off) rigged that way. Doesn't work so well with a Danforth type anchor.

Cheers everyone. The DORIS map on Google Earth is very neat. I have a well stocked freezer now :-)

The anchor was on Christchurch ledge. I recovered it at the weekend. The ledge in the area comprises of flat rock ledges with some 'blow out' holes in. The anchor had dropped straight down a hole about 3 1/2 ft deep in the rock face and was wedged solidly. In my attempt in shallow water and big swell to pull from various directions I'd successfully managed to wrap the anchor rope and chain around several vertical pinaccles of rock. It took a few minutes to swim the line and coil it all up as I went. I'd snagged everything going! Got a nice nip from a large lobster that was also residing in the hole my anchor had fallen into.

Interesting rock formations and no way of avoiding these holes with any certainty. During the dive I anchored with a large concrete 'bucket block' which worked fine.
