Figure 6. A SAS-12 close-up view of the Prudence Island shipwreck reveals several details on the vessel’s deck and a lobster trap (on the left). The most prominent features are the drag marks, where were made by the chain holding a marker buoy. Individual links on the chain appear as dots leading to the surface buoy, which is the lighter hazy area (to the left).
