Northside (Austin) Specs had KB Tooth in the big gold rolled steel textured cans a couple years ago when I was last in there.
If I understad it rightly, Foster & KB are a bit like a 40 of Peral or Lone Star would be considered here. Drinkable, but not what you'd brag to out-of-towners about.
The Castlemaine was good, but the Victoria Bitter was better--but, I like a bitter if I can't get a porter, stout or a Bock.
And, to swerve this back on topic, a river boat probably ought to have a couple kegs of beer on board, if not wooden crates of bottles.
