Cape Town - A Plettenberg Bay man had a brush with a shark which attacked his surf-ski near Robberg beach on Friday morning.A shark had bitten the surf-ski, throwing the paddler from it before it sank. NSRI spokesperson Craig Lambinon said rescue volunteers had been notified of the shark encounter shortly after 08:00.“Five men, all locals from Plettenberg Bay, reported that while paddling on a regular paddle one of the surf-skis had been pushed from behind violently, causing the paddler, Dave Manson, to be thrown out of the surf-ski,” he said.The incident was witnessed by some of the other paddlers.“Realising that it was a shark that had pushed the surf-ski from behind... Dave managed to get back into his surf-ski but it started to sink. It was noticed that the back of the surf-ski had been bitten off by the shark,” Lambinon added. Manson apparently abandoned the surf-ski and held onto that of one of the others as they paddled ashore. No one was injured in the incident “NSRI are urging the public to be cautious. It is now well known that at this time of the year sharks migrate close in-shore to feed as part of their natural habit and NSRI urge paddlers, surfers and bathers to be cautious and to be aware of this natural phenomenon,” Lambinon said.
