The Seattle water taxi docks at Pier 55, next to the ferry terminal. On the ride back from Seacrest, we passed close to a ferry. That's the ferry wake in the background. The captain announced that we might get rocked around a bit by the ferry wake, but I think this Coast Guard vessel might have been what she was really worried about!
The Coast Guard officer does not seem pleased that we were so close. Check out the full size view to see the expression on his face.
