To give folks a sense of the scale and frequency of anchor dragging incidents we present a chart showing Prince Rupert anchorages and a series of images showing the January 30th 2020 AIS tracks of some of the vessels which appear to have dragged anchor:
Pedhoulas Commander at anchorage #15, Sakizaya Diamond #6, Whitehawk #5, Santiago Basin #17, Kurenai #25, Scarlet Island #29 and Belatlantic #4
Images may be distorted in some media.
