Graham and Treena Kerr know what it's like to cook in a small space. "I spent 30 years as a sailor," said the former Galloping Gourmet and best-selling cookbook author. For two years in the early '70s, the Kerrs and their three children lived aboard their 71-foot ocean-going ketch. They navigated more than 24,000 miles, exploring the waters of the Mediterranean, Atlantic and Eastern Seaboard of the United States. After moving to the Pacific Northwest in the 1980s, they did another 6,000 miles in a 36-foot sailboat.
