Never trust a fabric bag to your precious camera. With your Swiss Army Knife you can put small holes in the flanges at the back of the box. You then thread a 3 mm static cord through these holes and the holes in the handle to tie it down to the deck eyes in front of the cockpit. This makes the camera ready for action shots. While I try to keep rigid containers to a minimum, there are some uses for them.
Fishing gear fits nicely into a compartmentalized plastic lure box.
Cookies hold together better in a Tupperware container. I left out olive barrels for a reason. The small ones work well when full. Just remember to keep them full, otherwise there is wasted space. I am a firm believer that as you eat into your boat, the bags should diminish in size.
