If you're looking to store stuff that has an edge or lip that can be fastened under something, check out how I did my plates and bowls here:
You can see the angled sticks on each side of the plates and bowls...they're rebated so that the lip of the plate/bowl is caught under the edge of the stick, and wedged in by the angle.
This would probably work quite well in a hatch, as it would be more vertical when traveling. I'd guess that you might have to put some kind of flat base behind it if your hatch skin has too much curvature, tho.
Good luck!
