How about casting your own?

I'm launching a new product - an Anchor Mold for drift boats. It's a steel mold for making a 4-sided inverted pyramid up to 75 lbs.

The mold sits on a turkey fryer burner, you load your lead in the mold and add heat. No pouring required. No guessing about weight, what you load is what you get.

You can recast old anchors, adding weight if desired. There's a clamp-on holder for the rope eye/u-bolt.

We'll be selling the molds, the clamp kit and sets (2 or 4) of stainless steel u-bolts at your local sporting goods store. We're also setting up a rental program for those guys that don't need one that often.

The molds have been ready for a while now, once we get the corporate paperwork dealt with, you'll see them around.

That is a great idea. If it is reasonably priced, I'd bite.
