Looks like you had some fun out there. I had quite a few run-ins with a hammerhead here in Malibu. As you said really awesome and graceful when there are others around, when you are alone though... that's another story.
Glad you didn't get knocked out of the kayak.
My run in, involved a 8 ft hammer head broadsiding my kayak and attaching itself to my gameclip thrashing about for 30 seconds. Had to slap its flat stupid looking head with my fishing rod. Then it circled me for about 5 minutes as I paddled all alone back to shore. Learned my lesson not hang fish off the side.
In the future what I might suggest is sacrificing one of those lings you had there. That's how I got the shark off my tail. I threw a calico that I had about 30 ft from my kayak and left. The shark will go after that.
