The Coast Guard reports 55 people - five of them with injuries - had to be evacuated from the Steamship Authority ferry Iyanough when it hit a jetty in Hyannis harbor and wound up on the rocks around 9:30 p.m. on Friday.
A Coast Guard helicopter transported five injured passengers, then returned to lift up 10 other passengers who couldn't navigate the slippery rocks on which the boat wound up.
Six people, including the ferry’s captain, engineer, and Coast Guard marine inspectors remain aboard Iyanough. A tugboat and a commercial towboat company are also on scene.
The Coast Guard will work with the Steam Ship Authority to assess Iyanough’s damage, and ensure safe navigation in the area. The cause of the grounding is under investigation.
