It all depends....
I very curious. After all the stories I hav read, and heard around the dock, and from friends about " so when we bought the boat and lit the stove, we couldn't see the flame, and the next thing I know, I'm on fire" or versions thereof...why would angone ever consider alcohol. NOTE" Not arguing with you, just can't see WHY since it seems t
o be recognozed as so dangerous???
Absolutely true... but only for
PRESSURIZED alcohol stoves. The fuel is under pressure (in order for the burner to work on that type of stove) and if there's a problem and you do not catch it quick, the fuel will continue to flow into that burner due to line pressure. Same situation if there is a leak near the burner. While an alcohol flame can burn yellow, they often burn a light blue. It's a hard flame to see.
The problem does not exist with a NON-pressurized stove like the Origo range that we have been using for many years.
So, the problem is not the fuel, but the type of burner and the requirement for pressure in those old stoves.
I certainly would not want a pressure alcohol stove on my boat, although I know other boaters that have used them for many years with no problem.
Sidebar: if you do not properly install and maintain a propane system and learn how to safely use it, you can perish considerably quicker than you would if a pressure alcohol stove happens to catch fire.
Any fuel can endanger you, whether it only burns or explodes...
