Install a plastic coated wire rack, large enough to hold the stacked boards, on the inside of your cockpit locker. Locate the rack so you can open the hatch cover and drop the boards right into it (i.e. on the bulkhead the locker shares with the cockpit side). This storage keeps the boards both very accessible but out ot the way.
If you put the boards in a cloth laundry bag before you drop them in the rack, they won't get scratched up over time.
