Re: Alcohol Stove - Non-Pressurized
Before owning my current boat, I had always used propane, diesel or solid fuel (wood). Having had an Origo for 4 years now and cooking many hundreds of meals on it, I am very satisfied. It is very safe provided that you take it up on deck to fill it and wipe up whatever you spill. It is very cheap to run, we get about 50 days of cruising per gallon of alcohol which is $10-15.
There are only 2 things that I feel a propane stove does better. The first is that a propane stove will boil a really big pot of water faster but as long as you are not cooking for 8, this is not an issue. The other is that you don't get great control trying to turn the flame way down to just keep something warm.
Unless you love cooking or live aboard and cook all the time, I think that the non-pressurized alcohol stoves provide the best bang for your buck. They are totally unlike pressurized ones.
