I used to paddle my fishing kayak out on the Chesapeake bay 1-2 times week. Every now and then a 5-6 foot Sandbar shark, or a Sandbar Tiger shark would swim along side. I would nudge them away with my paddle. It was quite a shock the first time, but it became more amusing over time. I did see some really big shark fins out there when I was trolling for Cobia's, but they were never close enough to identify what species........those made me a little nervous.
The only real frights that I ever got were those darned dolphins. I would be trolling some lures and the dolphins would bust out of the water in front of me. I had a thermos cup of coffee go over the side once after being jolted me out of my serenity.....lol. They are really beautiful creatures.
I know this isn't a answer to your question....but I thought it was fun to throw out there.
