The 72 meter long, 1816 dwt freighter Perseus collided with the 33 meter long, 366 gt tug Westsund on the Kiel Canal.  The Perseus was en route to Hamburg from Oxelosund in the Kiel Canal when a barge being towed by the tugs Westsund and Vorwarts had swung perpendicular to the fairway.  The freighter attempted to avoid the barge, but struck the port side of the Westsund.  The barge continued forward and struck the stern of the Westsund.  Both the Perseus and Westsund suffered some hull damage.  No reports of injuries.  The barge was berthed at Rendsburg for repairs.  The Perseus proceeded to Brunsbüttel where it also entered a yard for repairs.
