camping gaz is a mix of both gases so it must hold the pressure of the propane and the propane is mainly add to boost the pressure

Then just borrow a spare local bottle when you need to fill. The homebase bottles are grp so you can see the level of liquid inside.

I think the OP reasons was because he can no fit a different bottle other than a "camping gaz" one because of the gas locker size

Yep, noticed that, the Gaslight bottles post was answering danburys long distance cruising question. The grp bottles are great in that respect as you can see what's going on in there, think I'd be a bit wary of camping gaz bottles. But probably still do it with care.
Those gas soldering irons get through a load of gas as well.........

If that is the case why does the pressure in a camping gas bottle fall to the point where it is unusable below about 2 or 3 degrees C ?
A far as I had previously managed to discover butane/camping gas was in fact just butane although what is sold as propane was in fact a variable mixture of propane and butane.

I think you will find that most long distance cruisers end up doing what I do and refilling their own bottles or a local doing it for them.
Thanks to all the posters for useful comments and even to those who worried about (my) safety. We all have different skills and capabilities. After taking a science degree and spending my formative years in laboratories handling all sorts of dangerous materials, I am confident in my ability to refill a gas bottle with care and precision, doing it safely outside in the open air, away from any ignition source, checking with digital scales to ensure the bottle isnt overfilled ( actually leaving an additional margin below the normal margin) , checking that the valve has sealed properly etc. It isnt exactly a high tech operation to refill a gas bottle.

I set off with a couple of Calor Gas propane 3.5kg cylinders and managed to get them filled in Cape Verde, Brazil, Argentina, Uruguay and Chile. If you ask around the other boats in the harbour there's always someone who knows a man up a back street who knows..... etc. It was never a problem, and often it was entertaining. I once got them filled at a Chilean navy base and they came back heavier than ever before. Thought I'd got a couple of bombs on my hands.
I carried a set of universal adapters from Socal, but never used them.

On the long distance front, the only places we had problems were the heavily regulated regimes of Oz and US, in both of which we bought new cylinders (useful anyway to try to fit a larger cylinder than the standard Camping Gaz or similar sizes). Everywhere else, there would be somebody who find a way of filling any cylinder. We also decanted from large cylinders in cooperation with other cruisers.

Your points about the pressures decreasing are not valid. If it was compressed gas it would be true BUT we are talking about compressed gas and a volatile liquid which gases easily. So as long as there is liquid gas present then the pressure determinator is the temperature!the first bottle is say at 10 psi and you decant to camp gaz bottle 1 at 80% of supply bottle ie 8 psi and lowering supply bottle to 8 psi
supply bottle is now 8 psi and you decant to camp gaz bottle 2 and you wont get the same charge because of the lower supply
plus what he said above
a note for you all a few farmers get propane cheap and turn the bottles up side down to decant them into their LPG range rover as one would
then we get a job as the system stops and we say you have bean using bottled propane and they say no I haven't,
so I tell them to let their petrol station know their lines are full of rust and crud then as the range rover LPG fuel filters are blocked solid
the reason gas bottles are used upright and get filled over and over and the **** builds up on the bottom and when it is turn up to decant the liquid the **** comes out to and this can also stop the valves sealing

Propane boils at a lower temp than butane, that's why it is added, that's why I put a bottle of propane on the boat in winter, it delivers gas, IE boils at a lower temp than butane.

That is only true in the case of Camping Gaz disposable cartidges.
Camping Gaz refillable cylinders (904,907 etc.) contain only butane.

The boat next door to us in Rabat had the same problem as you wen refilling his USA bottles from a local Moroccan 22KG bottle. I discussed the operation with him as I was about to re-fill my own bottles ( although in the end we discovered it was much cheaper to buy a local bottle at around 7 EURO for camping GAZ or 1 EURO for a refil). He paused the operation for a while and 'vented' the bottle he was filling letting out some GAS. This solved the problem and he was able to complete the refill
Interestingly now I am in the Canaries and I can get my UK Calor bottles refilled easly, cheaply and legaly - the gas plants here offer a service to cruisers and it is much cheaper than camping GAZ or the local bottles. Also saves me having to refil my bottles myself which I dislike but have to do sometimes.

Was a little while ago and these things change, but istr being able to get Calor refilled on one of the top Islands but not on La Palma. And just to confuse things more new cylinders were being introduced in Spain which had made it to the Canaries but not to Cadiz where I bought one... (this was before investing in a socal adaptor kit)
Was always a good excuse for a treat of a hire car for a day and a drive round the island stopping off at the the gas depot

Can't get Camping Gas filled here in Turkey any more - but you can do it yourself!!!
The weight of an empty 907 is approximately 3.75 Kg, a FULL 907 bottle should be 6.5 Kgs - that's 2.7 Kg of liquid gas. But if you leave it filling - from an inverted Turkish bottle - then it can get to 7Kgs. This is dangerous as they must only be filled to 80% to allow for expansion in the heat. So if you don't want yet another bottle to go with your Greek, Italian, etc., collection then with extreme care and a "borrowed" local bottle you can do-it-yourself.

That's useful info, thank you.

They vary a bit but the actual tare weight ( in kg) is stamped on the base ring although there are so many numbers on some of them that its not always easy to figure out which is the tare. They should contain 6lbs of butane hence the rather odd figure of 2.72 kg.
