Here's a pic of an original 30# lead-body Animal Anchor for reference only.
These get mentioned from time to time and if you haven't seen one, here it is.
It was called a Ramsey Anchor and later the name was changed to Animal Anchor. They just stick.
The new ones are all steel.
Buzz Ramsey and Willie Illingworh were buds and I think they cooked up the design. My boat has an anchor nest for this anchor on the stern.
Very tidy.
