This is a low tech solution I came up with for stowing a Danforth style anchor. There are two teak 'feet' that support the anchor just above the deck. They are shaped to discourage movement of the anchor towards the centreline of the boat. The anchor can be slid fore and aft on these feet. My anchor has a flange on its base at the centre that hooks very nicely into the base of the pulpit (hidden in this photo). A bungee holds the anchor to the pulpit to prevent it from tipping.
