A crew out fishing in Cape Cod Bay earlier this week had a once-in-a-lifetime experience.
And it was all caught on-camera by Tyler Macallister who was heading out to go tuna fishing.
"That is a huge white shark, dude! That is a huge white shark. Look at that thing," Macallister said.
Once in a lifetime, that's how Macallister describes his experience this week.
"I was in awe. I was amazed. I was loving it."
Monday morning, he was leaving Cape Cod Bay when his boat came up along-side a shark.
They realized right away, it was a Great White.
He pulled out his cell phone to catch it on video, then ducked below deck for his GoPro camera.
"I am less than ten-feet from this fish right now," he said.
Macallister's shadow is clear at the bottom of the video and is small compared to the shark.
He estimates the shark was between 15 and 20 feet long.
"For six-and-a-half-minutes, the shark and I played a little ballet or dance or waltz, where she checked me out, I checked her out."
He said he's seen sharks before but this was something new.
"I've seen plenty of sharks, white sharks, all kinds of marine life in 29-years of tuna fishing, and this was, without a doubt, the one or two most incredible spectacles I had seen."
It was a spectacle he said, one he wanted to share with others, so they could see what he says he was lucky to experience.
"Great whites are definitely an unusual sight in this area," he said.
The Commonwealth of Massachusetts has allowed him to name the shark after his daughter Alexandra, it's all part of a shark tagging project that tracks sharks seen along the east coast.?
