The 46 meter long, 98 dwt ro-ro passenger ferry Spiekeroog 4 ran aground at the harbour entrance to Neuharlingersiel, Germany.  The ferry was en route to Neuharlingersiel from Spiekeroog with 140 passengers when it became stuck just outside the island port. The Skiekeroog 4 requested assistance with the DGzRS lifeboat from Neuharlingersiel responding.  The lifeboat tried to free the ro-ro ferry, but the Skiekeroog 4 would not budge. The ferry would remain stuck for another 7 hours until the rising tide allowed the Skiekeroog 4 to break free and berth in Neuharlingersiel.  Passengers were offered free meals during the delay.  No reports of injuries, damage or pollution released.  Reports state authorities will conduct a survey for any new sandbars in the area.
