The 105 meter long self-propelled barge Sinn went aground on the Danube River near Regensburg, Germany.   The Sinn became stuck along the shoreline after a navigation error and swung perpendicular by the river until the stern became stuck on the opposite bank.   The Sinn blocked traffic on the Danube for a few hours until it was refloated.   The self-propelled barge proceeded to Mühlhamer Loop where it dropped anchor.   The Sinn was en route to Passau from Deggendorf with 613 tons of soy.
