I fought this beast for 3 hours on 30lb p-line xx. until it finally lost its spirit and had succumb to the man. 15 feet away on the surface from 2 gaffs and BOOM!. The largest mako I have ever seen in my life took one bite.One mouthfull and half my easily 150 lb class tuna was gone. There was another second smaller 300 to 400 lb class mako that was 8-10 foot long that came in immediatly after we dragged the convulsing carcass over the rail and went straight for my outboard like it was a chew toy or something. The bigger one kept going back and forth under my boat.Huuuge mako!Scary huge,4 feet longer than the beam of my boat. We put it in gear and relocated to about a mile away to recollect our thoughts on what had just occured.
