I've got a simple Coleman stove that sits under the lazarette in the cockpit, and I pull it out to cook as required. I set it on a piece of plywood to protect the fiberglass from the heat. Then again, I've got a 22' Catalina. If I had a bigger boat, then I'd likely have an Origo non-pressurized alcohol stove permanently mounted.
What kind of boat is this going into?
