The Canadian Coast Guard Zodiac Hurrican

 Occasionally I will see Coast Guard boats as I boatwatch.

This was group of Canadian Coast Guard in a Zodiac Hurricane boat.  I'm not sure of the model.

I think this is used in a similar way to the US Coast Guard smaller boats.

I think they saw me as they passed.  I'm not sure where they were heading though.  I'd imagine with the number of boaters on the river, they were busy.
