Spare gas (propane or LP) can be safely secured in the L380 front locker, which is drained.
Bottles of alcoholic beverages can always be stored. Especially on a Lagoon. No buts, no exceptions, no equivactions. Isn't that really why you bought a Lagoon?
Bottles are what must be stored. Glass bottles. Drinking beer out of anything other than bottles is very poor form! Not what you bought a Lagoon for. (Ok, wooden beer kegs are good too, but a bit of a stretch on anything smaller than a L450 with a 6 t payload.)
Canned beer is for desperate times such as life rafts, capsizes or being marooned in uncivilised countries. If you are drinking water
from foil sachets then consider canned beer. Otherwise keep things civilised.
Wine is meant to be stored and consumed from glass bottles. There should be laws. There probably is an EU or EC edict if it can be found. Life is too short to drink wine from boxes, bladders or plastic containers. Economise by buying
plastic anchors, Chinese outboards, used batteries, etc. instead.
A liquor cabinet is supplied on Lagoon catamarans for BOTTLES currently being consumed and with care, spare bottles can be safely stowed under floor boards. Being below waterline this allows the most stable temperature for wine bottle cellering. This important design feature should be utilised to the full! Heck, some catamaran
designs don't even have the ability to store wine below the waterline.
Take care to pack with foam or cloth between bottles. We contain bottles in insulated cooler bags under the floor and insure that through hull
valves are unhindered.
