A smallish delta or plough always holds well in sand and mud.

I swear by a 'Bruce' type anchor aka 'Trefoil or Claw' great in mud and sand and hard - in fact almost anything - plus nothing too sharp to damage tubes etc. Might get by with a 2Kg but certainly ok with a 5kg for ribs up to 6 meters.

10 kg is way too big, we have that to tie our 5 tonne yacht to the sea bed.

You could do worse than look at the smallest Aliminium Fortress anchors:

The come apart and stow in quite a small bag, needing about a minute and a spanner to assemble.

Bruce. A 6.5kg has never dragged with my 7m Vipermax attached to it. Don't forget approx 3/4 of a boat length of galv. ground-chain. 8mm would be plenty for a 5m boat.

Keith, the anchors listed here already have great holding potential, but they also share the disadvantage that they take up a bit of room - and you don't have a very big boat. If space is at a premium, and you want reasonable holding for weight - you could think about one of the Danforth type anchors which will fold flat for storage.

As has already been said - chain is important to keep the pull horizontal. As a simple rule-of-thumb we tend to work with a piece of chain the same length as the boat

A serious question, seeing as I will also be in the anchor market some time around September... I don't anchor in any regular use, so when I use it will be because I *need* it.

Anything that is too big to handle, lift over the tubes easily (either to put in the water or pull back out) risks damaging the tubes. Anything that combined with the heavy chain and rope is too heavy to pull back in risks your back. Then there is the innevitable larger size which means you may have to sacrifice something else (e.g. length of rope/chain) to store it.

yep bruce for me too

Yep I agree with some of the other posters in that a Bruce has never let me down on my XS600, I have a 5kg for normal use and a 7.5kg as a spare and for when I need it to really stay put, a usefull guide on what size bruce and type and lenght of chain can be found here.

http://www.isealife.com/Bruce%20Anchor%20page.htm

Which gives sizes for normal and storm usage.

the worst I have put mine through was anchored in a force 8/9 overnight in full tidal stream and it never moved even through 3 changes in tidal direction, It was however rather painfull watching it from the campsite on shore as tents were going everywhere .

As my RIB has enough storage space I carry two anchors. A small folding Grapnel, and a Danforth. The Danforth is great for soft muddy bottoms, the Grapnel for hard rocky areas.

I have even used the Grapnel to recover a friends anchor.

I would however advise using a trip line with either type!
