It's a bit like solving a puzzle.
I made a diagram of all the
storage spaces, noting their location and dimensions. I'm anal about taking aboard only what I'm going to use and if I don't it gets
sold or given away. There never seems to be enough space for stuff!
I then tried to figure out: (1) the item's I'd use most often, (2) the items I'd use rarely; (3) the items that were heavy and therefore required some thought about storage; and (4) the items that required special storage (height, weight, caustic,...). The most used items get stored into drawers, with other items further
outboard or lower. I also make sure the drawers have
latches so they don't go flying underway.
I take off all the paper including labels. I used a permanent marker to write the contents on the top and bottom of the cans. Paper onboard is a breeding ground for roaches and bugs so as little paper and no cardboard onboard ever.
I try to maximize the storage space. If 3 tall layers are too high, then how about 2 tall and 1 medium height layers? I try to pad the layers and sides as well to prevent "clunking" or damage. I make notes in the layout and database.
I try to stack same shaped items together (round cornered bottles, round bottles, canned ham,...). I use old socks to protect the glass from breakage and movement. I have no problem squashing
toilet paper rolls. I use reusable wipes instead of paper towels if I can. Sometimes pouring contents of a bottle into another style of container can make storage more efficient (and remove that thin walled container from the boat).
I vacuum bag as much as I can. 5# bags of rice, beans, flour, etc get repackaged into 1# bags for easier stowage and less chance of going bad. I remove the cardboard from the pasta boxes, label the packages with a permanent marker and repackage as well.
I'm not a fan of nets, hammocks, or hooks. I've seen the results of a hammock full of fruit gone postal.
Some items require air circulation so I give that special treatment. Some items don't co-habitate well (onions and potatoes for example). Some items require attention (turning eggs).
I stored the heavy items as low, aft (chain
rode made that a requirement) and near the centerline as I could.
Getting things figured out the first time seemed the toughest task. After that, you may modify the locations but most of the work's done. Don't forget ventillation and adding a porous layer in the bottom of the storage space and allowing a bit of air to circulate can prolong the life of those cans and bottles.
