What I have is a yard sale repurposed Yachtman's anchor I picked up for $15.00
The style with the big flat plates (pointed) and a center swinging attaching bar.
I did modify the opening of the swing a little for more of a grip/resistance.
In sand, dig a hole to get the plates in pointed down, in Muskeet (Loon Shit), pound into
a good place, hopefully with some roots to help, winch away.
I store it either flat on cargo area floor, or vertical against body side strapped to roll bar if I need the flat floor. In the vertical position, it has started some interesting comments at the Rendezvous Start area, "Is that thing so little, it floats away at water crossings?"
