The Hot Tuna crew witnesses the real-life dangers of tuna fishing on Sunday's season four premiere of Wicked Tuna: Outer Banks.
Only ET has an exclusive first look at the intense episode, in which first mate Jarrett Przybyszewski becomes completely submerged by a 15-foot rogue wave.
"When that wave was coming to the side of the boat, I didn't really have an idea of if I was going to get tossed over. All I knew is that there was a big wave that was going to crash into the cockpit. I knew I had to hold on to something," Przybyszewski recalls. "There was a split second where I was underwater, thinking, 'I'm holding my breath on the Hot Tuna.' If I didn't see that wave coming and getting prepared for that wave to hit, there's a very good chance if my back was turned towards it, I would've been swept right off the boat."
"In 12 to 14-foot seas, you can't just turn the boat around and go get you," he continues.
"The way the boat was in that sea condition, in that current, if that wave would have blown him over the side, there's a chance he may not be here anymore," Hot Tuna captain TJ Ott adds.
