I, and many others, use a Cobb on board regularly.
I use it for baking (bread and cakes), as an oven, as a grill and as a hot plate. In the warmer months the Cobb is my kitchen. It produces the best pizza outside of a proper wood fired pizza oven.
Bought the compact model at the boatshow in Germany. Very nice package. much smaller then the Cobb but not suitable for families. All stainless steel. Waiting for spring to test it...
