The 20 meter long trawler Zk 12 Pieter Dion went aground close to the shore near Schiermonnikoog, Netherlands.  The vessel requested the assistance and two lifeboats responded.   With some difficulty, the lifeboats were able to connect a towline to the trawler and refloat it.   The Pieter Dion had several nets damaged, but the vessel was in good shape.   The trawler continued under its own power.   No reports of injuries.
