Anchor size for small dayboat on Solent?

[dunedin]

What size anchor do you recommend for a small (5m) powerboat (50hp) used on the Solent. Primarily for safety backup.
Probably the folding grapnell type.

Views? Thanks

I have a folding type for my dinghy and not impressed with it. It only seemed to work after I had buried it !

Thanks, as a flappie sailie boater I started at Jimmy Green marine but they didn't give anythong for grapnell types (perhaps telling, and I am a Rocna fan for big boat, but stowage an issue here).
What do folks use on RIBs for example?

Id probably go with a danforth style anchor for a small boat, due to the fact that its mostly flat when packed away so shouldnt take up too much space.

with a length of chain - maybe 3-5m, then rope for the remainder.

those folding grapnel anchors ,whilst they do go very small and light when folded up, I have found them not brilliant for holding.

I'd suggest a 4kg Delta. I use that in a 4.5m RIB. Great holding power, and easy enough to handle. 3m of s/s chain, then rope. Mine is painted in bright orange gloss paint to make it nicer to handle and easily seen by swimmers at the beach.

Ultimate solution if you don't mind the cost would be a 5kg Ultra anchor.

Folding grapnel anchors don't hold well

That's exactly what we use on our 7.4m rib with 4m of chain and then rope,. Always holds well and stows in the bow locker easily.

Interesting, thanks. The Danforth type generally have too many sharp edges and difficult to stow neatly for an occasional / emergency use anchor.
But anybody got experience of these folding spade style anchors - eg 4.4kg s/s or 2.3kg alloy? Ankerplex Anchor - Stainless Steel

We’ve got a claw type anchor onboard that so far has been solid as a rock. Annoyingly it’s just the wrong shape for the minimal anchor locker so have been considering a folding type too.
