If you go on just about any large boat, what do you find? A propane stove. Surely, there is a danger, but how great? I wouldn't think your risk is any greater than that on, say, a Grand Banks. We cook in there all the time. Sure we had a small fire, , but it went out on it's own(egg carton in propane fire, back into fridge, never even knew it happened) I think you are being overly cautious. Who needs frozen Cajones?
