The 32 meter long, 40 dwt Adler IV went aground between the islands of Sylt and Amrum near Hörnum, Germany with 160 passengers on board. The master of the Adler IV had misjudged the water depth and went aground. Several vessels responded from the DGzRS and Coast Guard to the scene. Passengers were transferred safely to the sister ship, Adler VI. No reports of injuries. The Adler IV remained aground until the next high tide when it refloated and continued under its own power to Hörnum.
