We have a Bruce on the Sonata. Only used it once, for a lunch stop, and it
worked fine in mud. When I hauled it up, I found that only one prong had
actually dug in. It was fairly thick mud - it wouldn't clear by swishing the
anchor in the water.

My experience with the Bruce anchor is that it tends to dig in only
proportional to the load. If you didn't take a heavy strain in setting
it, it might have only dug in one fluke a little bit. However it seems
to take a good bite quickly (unlike plows or Danforths, which you can
drag across the bottom for many yards) when a strain comes on the rode.
