In case this helps, here is a picture of a Manson Supreme 35 lb anchor on CLEO, my 2002 C34. I originally fastened a large bail to the rear of the anchor roller to secure the anchor shank. This did not work since one must bring this anchor on-board, with the windless, without stopping the last several feet, which often caused the anchor shank to hit the bail with enough force to bend it backward. The second photo is a closeup showing the current latching hardware to secure the anchor shank once the anchor is aboard. The latch consists of two stainless cheek plates bolted to the rear of the bow roller and with a 3/8 inch pin that can be slid open or closed and locked in place with a clevis pin. This arrangement is very sturdy. One can also lock this anchor in place by sliding the 3/8 inch pin through the slot in the anchor shank.
