3.2kg one of these Force 4 Folding Grapnel Anchor - From £7.50 - Force 4 Chandlery with 2mtrs of chain (appropriate sized) attached then 25mtrs of line 9or more if going deep fishing). Better to get the line spliced to the chain and a galvanised fitting from the chain to the anchor

For general purpose anchoring, a small Bruce, say 2.5kg and around 3-4m of chain will be sufficient (especially when you consider the conditions you are likely to be boating in - i.e. fairly benign)

At 3m is that a true RIB or do you mean a SIB? Loads of prevous topics on anchors available from a forum search but for small SIB's despite everyone knowing they are not exactly the best holders going I reckon many of us still use a folding grapnel type as they are just so compact/cheap/convenient. A few m's of chain helps too rather than all rope.

Don't get a grapnel as they fold when you don't want them too. I use one for my kayak, but would never for my boat. A navy anchor, danforth, or as recommended above a bruce type anchor, with chain the length of the boat and somewhere around 65 meters of rope.

Get one of these 'American' ones, and don't forget the forklift for the chain It won't pierce your RIB like a Danforth

Agreed - they are dismal at staying open ......

I would say user error with the grapnel rather than no good, I wonder why so many are used and sold, does make you wonder doesn't it

In all the 40yrs of my boating I have never lost a boat yet, maybe it's just luck

Just get a 2-3 kg bruce and be done with it. Don't bother screwing around with a grapnel or danforth. Grapnels are useless in many situations. Danforths are not SIB friendly.

WillK and PeterM do know what they are talking about.

I've got an original 11kg Bruce anchor on my mother ship and it is the worst anchor I have had, unfortunately due to design it is the only one that will engage in the bow, I don't trust it at all

Anyway, Danforths on RIBS are plain daft especially with an air or soft deck, we are talking about 3mtrs here aren't we

Maybe there should be a forum anchoring lesson get together to teach people how to anchor properly, but then I guess its hard to teach old dogs new/proper tricks

Anyway, there is a big selection out there and anything is better than nothing, just ensure it is compatible with your boating and seabed areas you use. Good luck

If you can read this and really look, you may see some anchors around as well

Lets see user error with a grapnel... Twist to release lock allowing flukes to fall down. Drop lock onto flukes and twist to fix them in position. Toss grapnel anchor overboard, letting out some scope. Gear up and dive down anchor line to check on anchor as done every time, before beginning scuba dive. Find grapnel anchor partially closed, and go what a piece of junk! Good thing the chain is holding it, fix anchor and continue dive. Not alcohol induced, but nitrogen narcosis induced hatred for grapnels

I can't think of an anchor that fits better in a milk crate than a 4lb danforth. For me the milk crate is ideal, since it can be easily carried, has vents allowing everything to dry, has holes to tie it down to the boat with, a hole to tie the end of the anchor rope too, and it holds my danforth perfectly as it has never flown out! Oh and also gives a good spot to tie lifejackets off to, along with a place to clip the tow bridle off to that I use for anchoring. Top that! Really it is the milk crate that I am passionate about LOL
