That's a cool idea. Good luck

You wont find me on the beach much at all, let alone in the water.  I stepped on a sea urchin once and not been the same since! lol.

Shark repellents sound good, but we have to remember they are the kings of the sea and we go into their world.  Sharks are instinctive creatures, highly intelligent and very curious.  90% of shark bites are out of curiosity, and the poor shark is left with this taste in his mouth he can't get rid of!  Us humans are yucky!

Hhhmmm, put our girls to work, they'd scare them all away!

Good luck with the business plans!  Hope it all works out.
