Three vessels collided in dense fog passing through the Kiel Canal near Fischerhütte, Germany. The 89 meter long tanker Kösterberg, the 100 meter long cargo vessel Grona Aalsum and the 131 meter long cargo vessel Prince of Seas scraped against each other as the passed in the fog. The Kösterberg was pushed onto pilings along the embankment. Neither of the three vessels sustained any damage. The Kösterberg proceeded to Kiel to be surveyed while the Gorna Aalsum and Prince of Seas arrived in Brunsbüttel to be inspected. All the vessels were allowed to proceed on the voyages a short time later.
