When looking for pots and pans for boating, you may want to browse the camping departments. Recently I was looking at the nestling pots, and realized how practical they could be on a boat with limited galley storage. There were stainless steel sets which I prefer for cooking. When outfitting the galley, the camping section may be a place to look.
More information on the galley and two burner cooking has been posted on my Squidoo Lens on Two Burner Cooking.
