When we posted a question about how sailors dispose of their garbage offshore yesterday, we were surprised by three quick posts suggesting that throwing paper plates overboard was fine because they biodegrade. In the meantime, a few commented that big reusable plastic bowls, or "dog bowls," as they are affectionately known, was the practice among pro sailors for limiting trash onboard.

Susan Shingledecker, vice president of the BoatU.S. Foundation sent us a memo from the U.S. Coast Guard with updated regulations on garbage disposal offshore; it states clearly that throwing paper overboard is illegal in international waters as of January 1. 2013. She notes that the U.S. has not yet adopted the change but that we are still bound by the rules. If you are going on an international sailing voyage, such as to Bermuda, you must follow international regulations.

"These regulations apply to ALL ships, big and small. If you wouldn't want a cruise ship doing it, then you shouldn't be doing it," says Shingledecker.

Among the items listed as "discharge prohibited" in the new regulations are: plastics, synthetic ropes, fishing gear, plastic garbage bags, cooking oil, lining and packing materials, paper, rags, glass, metal, and bottles."

You should also note that most island nations charge garbage disposal fees when you arrive. So reducing your garbage is a good idea. Also landfill space and recycling infrastructure on small islands is usually quite limited.

We did find some nice titanium camping bowls... Here are some West Marine versions with rubber bottoms to keep them from sliding.... and a collapsible bowl made of silicone.

If you have suggestions about where to buy good "dog bowls" for an offshore trip, please do share them.
