Hi

4kg is about the right weight but the length and diameter of the chain is just as important to keep the anchor from lifting.

Yeah I've also got an 8kg danforth with a better chain I could pinch.

I find the grapnel anchors to be pretty much worthless. They don't have enough resistance to keep from dragging in sand, gravel, or mud, and get hung up in solid uneven rock.

I'd go with the Danforth style if I were you. 8kg is pretty overkill though; on my 18' RIB, I use a 8 lb Danforth knockoff with about 15' of fairly heavy chain.

As stated above the grapnels are useless. Use what you got with the danforth, and some chain.

What anchor??

At least you have the sense to have it rigged in a "breakout "set up using Cable ties should it get stuck !

Better than nothing & use the largest one you have though i agree with the others it will need a long chain attached for it to work properly & the flukes need to be wide for it to work on sand .
on some types of hard seabed with the boat drifting in the wind or tide 4 fluke grapples can just tumble about on the bottom for a long time before it will set itself & stop the boat ,
3 fluke grapples if you can get hold of one dont tumble about as much & will set much quicker .
Also on folding grapples make sure the lock ring is tight ( cable tie it secure )
Last thing you want is for it to fold on the bottom !

I use a Bruce type or Danforth depending what i am doing , one thing about the Bruce its designed to hold in much higher angles of scope before breakout & it doesent need as much chain for it to set & hold unlike most other Anchors .
One thing about Danforths they stow flat unlike the Bruce .

RIBase
For my 6m RIB I've got a chandlery's own version of a 5kg D Type anchor with 5m of chain, for use as my primary anchor. I find it digs into most seabeds fairly well (I'd guess any anchor would struggle in solid rock though). I also have a 4kg grapnel with 6m of chain as a spare or stern anchor too.

Anchors won't dig in on rock, but they should at least snag something. A grapnel will do this, but if it's uneven rock, the tines may get stuck in narrow crevice (occasionally becoming damn near impossible to free without diving on it.) To be fair, it's also happened with a Danforth type anchored up on near-horizontal shale.

Has anyone used a grapnel with success? I like how easily they can be stored & don't have sharp points!
Surely they can't be that bad, they seem to sell well!

They sell well because they're cheap & also store in small spaces.
For use over rocky ground I made a small grapnel from rebar (reinforcing rod used with concrete). Holds when it catches & - so far - has always come back up as the bar is thin enough to bend if its still stuck after the cable ties have snapped. I carry a short length of steel tube to bend them back again.
Doesn't fold up like the bought ones, but they don't need to be big.
Danforth for everything else.
