Canadian Coast Guard Reserve. Taken from The Duke D' Orleans II while on a cruise on the St. Clair River in Sarnia.
This was actually fairly difficult to get a good shot, as the boat was rolling and pitching while sailing. The water
at the mouth of the river and Lake is very unstable, with small whirlpools, and very strong undertows. You can see in the
photo, that the water looks smooth in spots, that indicates that there is a strong undertow there.
