I tried lots of places to find a simple way of getting a conversion from our European Butane cooking
system to US propane
after crossing the Atlantic. I found it impossible to buy Butane in the US. My cooker, Plastimo
Neptune 3000 runs on either. This seems to be simplest and cheapest option: European “Camping Gaz” System Adapter To U.S. LPG Cylinders #1190-1625
All you need is this adaptor ($75 ordered through West Marine) and a new propane
tank ($54 from a hardware
store) and off you go. It works, at least for me. Hope this helps other Europeans thinking of cruising in the United States or places where Butane is hard to get hold of.
For Americans going the other way, Trident Marine
make a similar convertor Propane to Butane.
The other option I was told was by a friendly boatyard in Annapolis
was to change the entire system at a cost of $1,600 which they were happy to do for us. And then another $1,600 to convert it back when you go home!
