In Sweden we have one system, in Europe there's another (and almost every European country seems to have one of their own aswell) and in the Caribbean they have the American type. In Sweden we use propane, in Europe butane and Caribbean mostly propane. Which shall we choose? The trickiest part is the size, we want to have them in a secure closed container with ventilation, close to the stove, that way they end up in our cockpit locker which has a small entry. The french Camping Gaz bottles of 3 kg have a very attractive size, they have a diameter of about 20 cm and we can easily fit four of them in the locker. They also seem to be the standard from Denmark to the Canaries. But...what do we do when we reach the Caribbean? Can we exchange or refill them there? Some say it's possible in the French islands. Since we are planning to cruise the Bahamas and Cuba the last two months, where it's unlikely to find butane, will our four bottles last until we reach the Azores? Today I have sent emails to the marinas in Rodney Bay (St. Lucia), Nassau (Bahamas) and Horta (Azores) asking for information about the availability of Camping Gaz. How long one bottle lasts is a big question, and searching the Internet I find different answers. I guess we just have to wait and see. / Captain Ingerup
