Oh it'd be sweet Chimo, but that's a 40 footer weighing in at 10 or 11 tons dry. Much more when loaded with fuel and enough food and beer for half a dozen of you fat bastards . I reckon you'd be lucky to pull 600 km out of that.
Mine might be 4ish tonnes dry at 30 feet. And yes, I will always ensure a bridge free track - if the ducks line up this will be an interim boat...
Cheers,
Tim
