There was a recent thread that commented on an open container on a boat, and how the rules are the same as on a boat. Another member commented that he drinks only when on the hook, which I think is common, but it also common while fishing. Is it true that the rules are the same on a boat as in a car? I believe that in a car you can be stopped with the ignition off, and still get an open container violation if the keys are in the ignition. I wonder if this is true in a boat? I don't know anyone that pulls the key(s) out of a boat at night on the hook. Also, what about people drinking while the boat is underway? Is this really illegal as it is in a car?
