RIBase
Anchor sizes for a rib

Hi all

I have a guardian G7 anchor which is a great anchor expect that it is too large to store in confort on my rib. I am looking for a smaller mor compact anchor for a 5m rib anchoring in sand is a 2 kg Claw large enough? or have you any other suggestions. I was considering making the shank and the legs either side of the fins shorter; your thoughs please

I think the basic rule of thumb says 1kg per metre boat length, but not too experienced in different types of anchoring ground, as I don't normally anchor anywhere.

I use a Danforth type anchor on my boat (18 foot RIB, 8 lb anchor.) As I recall, you need a relatively heavier anchor with the claw type anchors (Bruce, Lewmar knockoff, Delta, etc.)

My fluke type hooks up quite well in either sand or rock. Only place it has trouble is on flat shale (but then, so would any other anchor.) Unfortunately, that substrate is what's on my favorite dive sites.

I don't anchor in grass or mud too often, so have no experience with that type off bottom.

Personally, I use a Delta copy. Great anchor and you can get away with less weight because of the holding power, but not too easy to stow
