What are you planning to use it for? I'm not sure I have ever seen one for small boats.Anyone know where I can buy these online. The smallest I have seen is 3.6kg which would be ideal.

http://www.mushroommooring.com/Moorings.htmlDo you have a picture of one or can you describe it. The only Mushroom anchor I know of is used for a mooring on silt and mud. Didn't know there was one for everyday anchoring hence my confusion.
Yeah most of them seem quite large but American sites list these neat ones - the link shows a 15lb one but they go as small as 8lb.http://www.boatersworld.com/product/156790107msk.htm
Interesting, they give a holding power up to 10 times the weight of the anchor. That is very poor compared to "normal" anchors. A 10lb mushroom would give a 100lb hold. A fortress FX7 weighing in at just 4lb on an ideal scope set in hard sand would give over 2500lb hold.
Got a link for that? Sounds eeeeeeh..........Dumb?Thought you might be amused at this offering from Sea and Shore in bonny Scotland:
Inflatable Boat Anchor
OK ... it does begin to make sense when they go on to say ....
Designed specifically for safe and easy use with infltable boats. A mushroom anchor in a choice of three weights, coated in black plastisol.
Yes I thought it was odd the reference to "normal" anchors withat saying what normal meant.:g:Interesting, they give a holding power up to 10 times the weight of the anchor. That is very poor compared to "normal" anchors. A 10lb mushroom would give a 100lb hold. A fortress FX7 weighing in at just 4lb on an ideal scope set in hard sand would give over 2500lb hold.
An average 20 foot boat in a 30 knot wind has about 350lb wind loading on it so the anchor needs to hold more for it not to drag, this would need a 36lb mushroom anchor and it would be on it's limit of holding, whereas a Fortress of 4 lb wouldn't even be breaking sweat.
