That's kind of why I asked for more info. For example, I've known people who refer to the strangest things as "channel"s.
No, typically fishing would not be going on in a marked channel; at least an in/out of the harbor type. But in some areas, (downeast Maine, for example) every near shore bit of water seems to one sort of channel or another.
I agree about the arrogance thing; "screw you, I'm
workingfor a living!" does not make for good neighborly relations; any more than "screw you, I'm on a starboard tack!"
