Kayaks taste better than humans?

45 year old Adam Coca may be wondering if a great white shark decided that kayaks taste better than humans after his recent encounter.
While paddling off Pigeon Point Coca felt a sudden impact on the front of his kayak.
A second hit flipped the boat and tossed him into the water.
While he sorted himself out, he watched a great white shark continue chewing on his boat.
The shark gave up after spinning the kayak around several times and Coca managed to get it back to shore despite the damage to the boat and his equilibrium.

Maybe sharks think plastic is a good way to clean their teeth.
