Check out the chart. It says 140-180 lbs based on your guesstimate! Nice fish!
I never would of guessed it could have weighed that much. Probably better for me that it wasn't legal. It would of been dangerous trying to get that thing on board or getting a rope on it. You can only carry so much crap on a 12' boat, but maybe I'll at least get a shark hook on a bungey cord.
