I wasn't anchor shopping, but stumbled accross this anchor at Duhmans while getting some fishing jigs, it weighed next to nothing, and the manufacturer's decal stated that it was rated for a boat up to 19 feet, so I thought I'd give it a try.
Didn't hold at all, and I mean not at all. I don't think this thing would hold a boat with a 5 mph wind. I even had 5 feet of chain on it. Luckily I had my old anchor with me, and put it right back on.
Maybe it would work for a small 12 foot Jon Boat, completely useless for a fiberglass boat.
If anyone wants it, let me know.... I'm done with it!
