having lost an anchor recently, I've done a bit of research. The result (in my opinion) is that multiple anchors are required (unfortunately). When I recently lost my sand anchor on reef, I had the cable tie method in place, and I'm confident that the tie broke (115hp vs cable tie wins!) but that damn anchor just wouldnt come. Cooper anchors look great, but at $129, I'd be too worried putting it down on a reef, even though they recommend the cable tie method and suggest that this will get it off anything. I cant afford to lose that.
So what I reckon we need is some very smart fishraider to come up with a retractable reef anchor, where the tines retract back into the shaft when not in use. That would make them easy to store away, so that I dont catch my shins/knees/fishing line/rod on it every time I turn around. I've seen small grapple hook anchors around for yaks, but only up to around 5 pounds, maybe just a bigger version??
