So why do most boats on the UK canal system seem to use butane instead
of propane?

What advantages does it have?

Butane and Propane are both heavier than air, both Liquified Petroleum
Gas.

Butane burns hotter and has more heat per weight. But, its boiling
point is just about 0C (32F), so you don't get much gas in a cold
climate. Propane boils at around -40(C or F), so it is the only
component or principal component of commercial LPG in colder climates.

He probably means "Camping Gaz" which is a brand name for LPG
camping
appliances (stoves, lanterns, etc.) and their fuel. It is quite
common
in Europe and the canisters will contain a mix of propane and butane
in proportions that depend on the latitude. (This tidbit of
knowledge
comes from reading the content labels when I should have been having
fun instead ;-) )

Butane (C4H10 MW=58) is heavier than Propane (C3H8 MW=44) is heavier
than air (mix N2 and O2 MW=29).

Butane burns hotter and has more heat per pound. There may be a price
difference. You can't use it in winter. They take the same orifices
in the burners which are different from those used for natural gas.

The cynic in me says that none of them actually know what they're
using -- they just go to the supplier and say, "fill it up." It's
probably mostly propane in the winter and perhaps more butane in the
summer.
