Provincetown, Mass. — For a second day on Saturday, the Charles W. Morgan sailed out onto the Stellwagen Bank National Marine Sanctuary to be greeted by whales feeding on the bank. Along with her support vessel F/V Roann and NOAA’s R/V Auk, the Morgan was surrounded by whales and the whale-watching fleet as everyone sought to follow what was an unusually large gathering in the area this year. The wind was light and faded away, but not before the Mystic Seaport staff was able to record some remarkable video to document the day.
