I am waiting for it to happen. Maybe there is so much forage for them they don't mistake people for dinner. If it was rougher out there with more white water where people swim it would have already happened. If and when it happens i would think it would be a surfer not a bather. Is Chatham a place where many people surf? I have only been there a couple of times.
Nauset beach in Orleans has the surfers.The ironic part is the town has closed the bathing beach but the surfers are to the south of the public beach reached by 4x4s and the powers don't bother them with notices.The sharks heve been filmed taking out seals as far as N. Truro[Head of The Meadow beach].Kite surfers are the surfers in the Chatham area.When they dump they can be even more of an issue due to the distance from the beach.
A few years ago there was an article about a seal being eaten within 50 feet of the beach along that coast, I think it was Nauset, but could have been Chatham.
