Born and breeded here. I've never heard those terms used. I don't care what transport Canada calls it. The inner harbour stops at the JSB and after that it's the Gorge waterway.
Also nobody was less surprised than me that this happened. Biking past here every day I get to see how ridiculous the loading process for that barge is. Usually one end of the barge is about 2 inches off the water.
2 inches is really nothing at all to worry about loading a car ferry the same thing happens and not only end to end but side to side thats why caution is taken to load and unload evenly
