To start with, when I put the bow roller on the boat I didn't leave enough room for the anchor flukes to clear the bow of the boat. I started building a pulpit to extend the roller, but really didn't like how it lengthened the boat or how the fasteners lined up, so I decided to store it on deck. I built this plate to screw down on the foredeck. Rode tension with keep the flukes sucked into the line. Rode will run through the dorade and into the plastic tub you see into the photos or a square bucket if i can find the right one in time.
8 gallons of water in gallon jugs fit to the left and right of the tub for the rode and other often used short lines like reef ties. thermarest pad and sleeping bag in a waterproof bag as well as clothes under the foredeck. forward of that is a buoyancy chamber with access hatch where I store a spare halyard, mainsheet, and coils of useful line for any other purpose on the boat.
Aft is storage for the two large top hatches for the slot. Forward acrylic hatch, aft horizontal hatch and aft vertical hatch store along the sides of the cockpit/cabin. Aft is also where the beach chair, bilge pump, fenders, 3 gallons of gas and the 5 gallon toilet will store.
Here's the rough weather configuration. Opening at the aft end of the slot is roughly 30" x 16".
When the weather isn't so bad, I'll only have the front two hatches installed.
