What's the law on alcohol and kayaking??

[Loudog]

I see guys having a beer or two and I do myself ... while fishing. So I was wondering what the law actually is... Is it like drinking and driving DUI or riding a bike and drinking a beer?? Because you can get a DUI riding a bike because it's considered a vehicle. Is a kayak considered a vehicle like a bike or a boat? not really sure... And is it different in the harbor than in open water? I know on a boat the passengers can drink but the driver cannot if you're the driver on kayak and is it like riding a bike in Huntington Beach with a beer in your hand on the strand.
