Something like that?

I don't always remember which anchor goes in which category, though.

I remember once reading one of Rex's vehement dissertations about the differences between a plough and one of his SARCA anchors. And then visually comparing pictures of his and a Delta... and not really seeing the difference.

Happened to be looking at the Mantus website today (after the question about built in U.S.) and found their sizing tool suggests a 65-lb anchor for our boat, 1640 square centimeters of fluke. Our back-hoe (about 50-lbs) is about 1850 square centimeters of fluke. I don't se a quick way to look up fluke size of a Fortress, but our FX-37 (21-lbs) probably would be starting to get on the large size.

Perhaps fluke size may be at least as useful a classification as shape... or maybe a ratio of fluke size to weight or some such... although fluke size and overall weight and obviously moving targets as anchors get larger...
