I consider this frequently, especially since I am the only one out where I foil. No surfers, no foilers, just folks walking on the beach. I could see a shark taking a swipe as the wings might look like a fish. I also feel that if it did not stop the shark, it may get lodged in her mouth. Would suck to be bitten, and or to lose an entire foil rig as it swims away with it stuck in its mouth.
Crazy that the carbon fiber grabbed that tooth.
