Welcome back to the Fluctus Channel for an overview of the methods to protect sailors from scary sharks while swimming in the ocean.It doesn't seem like much but swim call is one of the craziest experiences. Once you realize just how clear the water is, how far down you can actually see and how there's virtually no bottom. It's a very unique state to be in. I went through the USCG egress training in Elizabeth City. Most fun I've legally had while still wearing pants. When swimming in the open ocean it is MUCH more terrifying keeping your head above water not knowing what is lurking underneath. As opposed to having a snorkel on and diving under so you can actually see what is down there. Learned that when I swam with sharks off the North Shore of Oahu in 6,000 feet deep water surrounded by Tiger sharks. I was on a coulpe of different aircraft carriers years ago and some of my best memories are seeing large schools of dolphins pacing the ship. Diving and breaking through the waves barking playing. Sometimes as many as approximately 50 or more. Didnt see any sharks but obviously thier out there. I remember watching nighttime launches of f18s f14s etc. At night its quite a sight seeing the flamage shooting 30 n 40 ft out the back of them as they screamed of the deck.
