Alcohol, believe it or not, is very dangerous.
Alcohol stoves, especially preasurized, can be as dangerous as propane. Alcohol flames are almost invisible and when it leaks it can be extremely dangerous. I had a galley fire due to alcohol leaking out. It was hard to attack the fire because the flames were very hard to see. Until I saw one of the galley curtains flare up, it was hard to determine where to begin fighting the fire. Our propane stove and oven have been a lot easier to operate, and are dependable and predictable. And, by-the-way, my installation cost was not as expensive as Doug quoted. The locker was a package deal, with tank and switches. Most of the boats in our area have gone to propane or an equivalent type.
