Can I bring a small camping fuel bottle (such as Primus Power gas) on the Smyril Line ferry MS Norröna between Hirtshals, Tórshavn, and Seyðisfjörður? I find conflicting information on the Smyril line website:
Liquid gas on board MS Norröna
It is allowed to bring max 20 liters of extra liquid gas on board MS Norröna. The tanks need to be of steel and need to be approved for the purpose.
That reads like a yes — under pressure, the gas in the Primus bottle is liquid, the container is made of steel, and presumably approved for the purpose. But further down, the same page also says:
Propane-gas on board MS Norröna
Extra gas tanks are only allowed to bring on board, if they are empty.
There is propane in the mixture, and the bottle is not empty — so this reads like a no.
The two instructions appear to contradict each other. What applies to a small camping fuel bottle?
