Standing on the light weight 1.5-lb Grapnel to press two of its three prongs into the lake bottom will usually increase the grip.

Snagging it onto a rocky bottom can get a good strong hold with a 17' canoe on a Maine river but will it work on Lake Winnipesaukee with a jet ski?

No. It's terrible. The slightest wave action pulls it.

You know what works amazingly well? The Mantus Dinghy anchor at the bow and dog anchor at the stern.

Well ...... let's consider their price ...... the Mantus dinghy anchor is $232.00 ..... the 1.5-lb folding Grapnel is $9.99 ...... and a concrete block, 8"x8"x8" weighing about 15-lbs is $1.48.

For $1.48 ....... the concrete block works very well on the sandy lake bottom and has a single large opening for attaching an anchor line.

Cost doesn't matter if it doesn't work or, worse, causes damage.

That volume of concrete (8" cube) would be about 0.3 cu.ft and weigh around 43 lb. That "single large opening would have to be huge for the block to weigh just 15 lb, little more than a third than without the hole. Of course, a 0.3 cu.ft block weighing 43 lb out of water has a net weight of about 24 lb when submerged.

A Lewmar 2.2 lb Claw anchor is $13.75 and it actually works really well. It's so worth the extra $3.76 to $12.27 compared to an anchor that does not work at all a and concrete block.

I really like the Mantus, and if I was anchoring overnight, I'd spend the extra money. The 73 lb anchor on my main boat is a Vulcan which is extremely similar to Mantus anchors in design and price and I spent more for it than I spent to buy my first motorboat, but I like security when I anchor overnight and the weather gets bad.
