The Burgzand Noord 9 (BZN 9) is the wreck of a 17th-century armed merchantman.
The wreck was found in the 1990s and investigated in 1998. It was recorded for the first time in 2007. The sediment layer in the wreck area eroded approximately 5 m between 1850 and ca. 1985. Subsequently, the area remained fairly stable, but from 1995 on the area began to erode yet again, by another 1.5 m. Over the last couple of years, sedimentation and erosion seem to be fluctuating, with some net sedimentation in recent years, but more pronounced individual wreck parts visible on site.
