I can't swear about your boat, but our Bluewater is designed to be beached with the bow on the beach. When we have done this We haven't really felt the need for an anchor at all. The bow is kept in place by the sand, and the rest of the boat is kept from pivoting by the boat being up on the beach.
If there was a significant cross breeze the kept trying to spin the stern I would probably run a skeg from the stern cleat out a hundred feet or so and pull it tight. For this we keep a stern anchor in a dock
box mounted on the back patio of the boat. But don't have any tackle handling equipment
to go with it.
To me this is a lunch anchor type of arrangement, and I wouldn't trust it in a blow, and certainly not over night. But for a fun afternoon it works fine.
