Late in the game I decided to divide the chain locker. First off there just isn't the need for that much room pulling single duty on a boat this small (in my totally inexperience opinion). The other side could still be used for storing additional rode and/or what not. But more importantly the divider provides nice support for the water tank's forward bulkhead. And the added surprise-the forward compartment drain makes a nice fillet! I have to add a small 'ramp' at the forward end to help the anchor rode spill but that will have to wait untill things are glued in place.
The top edeges of the 1/4" ply gets reinforced with mahogany strips with a triangular profile. The rational being the flat top provides a nice, wide surface for supporting the decking or hatch lids and the bottom has no edges to catch things on or split knuckles with.
Here's a shot of the anchor locker drain.
