Today we got propane.not easy.
We have 2 x 9 kg bottles .one was empty.the other in use since before Reunion
The gas place did not have fittings to fit our cylinders.luckily a recent cruiser had made up a hose to connect Malagasy bottle to Australian bottle to allow decanting,and given it to john.
So we bought a local bottle,connected the hose,and nothing happened.so we came back to boat,googled,then read Nigel Calder boat bible.
The trick was to heat donor tank with towel and hot water,and cool recipient tank.the propane then flowed down to fill our tank in about one hour
Returning the empty got our deposit back
