Not trying to throw this to OTDE material, but seriously, when I read that thread I was confused. Is there not a legal definition of being DUI, (which I worked out meant drunk in charge), over there..? Here on the other side of the world, we have a 0.05 legal level of blood alcohol - under that, either in a vehicle or boat, and you're good to go. At anchor for the night, one would never be breath tested anyway. Only learner and provisional licence drivers have a zero blood alcohol status for driving. I can't believe over there just having had a beer would put you in jeopardy..? Surely you get tested first..? For a country that does not enforce bike helmets, and even seat belts, in some states anyway, charging a boatie with being DUI for having a beer on board seems...well...weird.
