The Panama buoy

The calm swells of the Port of Panama gave the Fir’s crew a perfect opportunity to show the Panama Canal Authority how buoys are maintained in the U.S. As the Panamanian crew traversed to the whistle buoy, they searched for the black-hulled tender sporting the iconic 64-degree Coast Guard red, white and blue racing stripe. There it was, on time, dead center of dozens of floating cargo ships.
