Description
On the evening of September 25, 2017, at approximately 6:00 PM local time, a surfing incident occurred at the North Point break near Gracetown in Western Australia. The incident involved Catherine Vissers, a Belgian woman in her early 20s, and a 3.5-meter great white shark. Vissers was surfing with off-duty lifeguard Tom Van Beem, who was present during the encounter. Van Beem reported feeling a distinct water movement beneath his board before witnessing the shark make contact with Vissers. "I felt this water movement underneath me," Van Beem recalled. "I looked at the girl sitting next to me [and] she got knocked off her board. Then I saw the shark's body follow with the pectoral fin and the tail." Upon the shark's approach, both surfers immediately paddled toward shore at maximum speed. The shark did not pursue them. Remarkably, despite the forceful contact that displaced Vissers from her board, she sustained no physical injuries. Her surfboard, however, bore clear evidence of the encounter—distinctive gouges from the shark's teeth marked the surface where contact occurred. Conditions at the time included sea surface temperatures around 65°F, with calm to light winds of 6-10 mph and a waxing crescent moon at 23% illumination. The incident was classified as unprovoked. Following the encounter, the North Point surf break was closed as a precautionary measure. The shark's behavior appeared to be a territorial assertion rather than predatory intent, as indicated by the damage to the inanimate object—the surfboard—rather than pursuit of the swimmers.
