Without warning, a massive 600-pound mako raced in and nailed the marlin - just a few yards in front of me. At first, the crew had no idea what was going on and couldn't figure out what all the commotion was about. As for me, I somehow managed to remain amazingly calm throughout the attack. I figured that since there was no chance of me getting anywhere near the boat, I may as well record the whole event. I still remember thinking, "Man, that is one massive shark!"
