A serious incident occurred late Sunday night during a ferry trip on the Silja Serenade, which was traveling between Stockholm and Mariehamn. An elderly woman from Sweden sustained severe injuries, prompting an emergency response that included her evacuation via helicopter, according to Marika Nöjd, the communications manager for Tallink Silja Oy.

In response to the emergency, the Silja Serenade turned back temporarily towards Sweden to facilitate the helicopter's arrival. The vessel's return caused a delay, and it is expected to arrive in Helsinki about half an hour later than scheduled. The incident highlights the risks associated with maritime travel and the necessity for quick emergency response protocols.

As the investigation into the circumstances of the woman's injuries continues, passengers on board and the ferry operator are undoubtedly concerned about safety measures and the overall emergency preparedness of such travel routes. This incident raises questions about the protocols in place for dealing with medical emergencies at sea and the challenges faced by maritime operators in ensuring passenger safety.
