A single "Origo" burner (alcohol
fuel) is about as efficient, safe and idiot proof as you can find. After ten years of use, its stainless steel construction, portability and all around simiplicity, it has proven the best buy I''ve ever made for the boat. It can be purchased with optional gimble and clamping
fiddles. It is "pricy" at the outset but will give years of trouble-free service. Cheers, Richard.
