I remember in my 5th year of school we made cube shaped balloons from
plastic sheet stuck together with sticky tape, filled them with gas from the
bunsen burner outlets in the craft room, and let them fly off into the wild
blue yonder.  Definitely natural gas i.e. coal gas, in use there.

The UK yachtsman would presumably be using Calor gas bottles or similar
which contain propane, butane or a mixture thereof.  This gas would be
heavier than air.
