Actually, I'm certain that you will find them out there because the buyers of these found out they worked as brakes as they banged into the waves. The best cooler made for the cat was the Cool Cat, and they discontinued production because they were only selling a few hundred a year. They had two clips on them which allowed you to attach them to the tramp lacings.
Our Fleet treasures them; we've even learned how to resew new plastic linings in them. If anyone knows a new source, let me know...
