If you do get to the filling station (it's handy for spares and repairs too), be sure to look out for the little shrine to Rob that's been there for at least 15 years - it was still there in 2012, but haven't been up since then.
Definitely don't doubt Dawn - not if you value your life
Watch out with Sovereign, we had a load of cylinders filled one saturday evening (was a while back), on the boat the next day found that several cylinders only had 130bar in them.
Next time we went i took a reg with me when we collected them to check they all had good fills.
