Hi,

I've just switched to propane on my GRP canal cruiser due to the lower
freezing point.

But most other cruisers seem to run butane.

Why?

I've always used propane and I don't know any here on the west coast that
use butane. Perhaps in Europe

You are correct about the lower freeze point being an advantage. However
they both share the same safety (explosion) hazard.

Except propane is heavier than air and butane (e.g. camping gas) is
lighter than air..

I thought 'Camping Gas' was naphtha...

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 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.

Hi,

Thanks for the reply, I should have stated that I was in Europe, England
in fact.
