The maximum size for a Great White is 20'.

Good chance that fish you saw at Stellwagon was a fako, I mean porbeagle. They have been confused with White's before. I doubt a big white would rip out line as they most likely would barely even know they are hooked with a butterfly jig.

A 25' porbeagle is even more far-fetched than a 25' great white :hs:

Not to mention great whites typically don't breach out of the water anywhere but off the South African coast.

Here what I can say with about 99% certainty--assuming he's not totally yanking our chains--if what he saw was 25' long, it wasn't anything other than a basking shark. If it was a great white, he way overestimated its size--which would be understandable under the circumstances. It probably would have looked like a boxcar to me, too ;)

Um..ya...I assuming that in the excitement the fish looked a-lot bigger. There's a much higher chance of seeing a porbeagle than a great white jumping at Stellwagon. If you have ever seen a 500+ pound mako jump near the boat you would think it's a-lot bigger than it is.
