Addendum to Jerry's advice: If you are sailing on the ocean (not freshwater lakes) keep aluminum beer cans out of the bilge area. I kept some of my beer supply in the "bilge" and several weeks later when I went to get a cool one, I found it was curiously light weight as I picked it up. When I popped the top - No pop and I found it was half empty. Why? The answer took a bit of sleuthing, but what had happened was that there was enough moisture in the bilge to act as an electrolyte. Galvanic corrosion in the thin aluminum can material created a pin hole. Beer can pressure forced beer contents into bilge. So the moral of the story is, keep beer / soda cans out of areas where they might get wet. Never did have a problem with my wine bottles or plastic spirits containers. Connie
