Hi Scott,
I bought this one at last years Southampton show it has a slightly bigger surface area than the anchor fitted to cheetah but it is all marine grade aluminium and comes with a padded bag and only weighs 2KG.

I've used one of these (FOB) for years on my boats and anchored quite a lot over the years, they hold well even in strong tide. I have 40ft of chain on it, then rope. However I think they lack the weigh to pull into a pebbly/small rocks sea bed, and that's the only time I didn't manage to get it to bite.
On sand they are peachy; as a 30ish ft hunton rib found out after reversing onto my anchor line at shell beach in Herm.

anchors
Bruce anchors have the best holding to weight ratio. 7.5 kg with 10 metres of phil's chain and at least 50 metres of min 12mm nylon warp should hold your boat ok. The ratio of depth to warp length is 7 to 1 , e.g anchor in 5 metres, let out 35 metres of warp.

When I raced the Phantom up north it only matched the dimensions required as no weight was quoted - think it weighed about 16 ounces
