Damn that's a big arse shark. From the boat it sure looked like a great white.
Saw a large basking shark come up close to the boat when we were on a whale watching cruise out of Boston. The guide estimated it was about 12-14 feet long. Unfortunately I was on the wrong side of the boat to really get a good look at it. My mom was down front and got a better picture (hers is on the bottom). They're really wide.
Also the uploader misspelled craic. If you're Irish you should at least be able to get that right.
