Cold Comfort – This is the moment a 75-meter chunk of ice falls off a towering glacier in Alaska. The tiny speck waiting in the water to surf the ensuing wave? That's Garrett McNamara.
Barrel of laughs – In 2007, McNamara became the first person to ride a glacier wave. But the 45-year-old American is better known for surfing the biggest ocean waves in the world -- including a reported 30-meter monster off the coast of Portugal earlier this year.
World record – The father-of-three already broke the Guinness World Record for surfing the biggest wave ever -- a 24-meter swell in Nazare Portugal -- two years earlier. Nazare features a 5,000-meter-deep underwater canyon, churning up some of the largest and most dangerous waves on the planet.
Wave hunter – "Chasing big waves around the world means you never know where you'll be next -- birthdays, holidays, everything has to be dropped at a second's notice," said McNamara.
Surfer's support – McNamara says he couldn't have had such a successful career without the support of wife Nicole (pictured). "She's on the cliff with the walkie-talkie guiding us where to go. She's been a part of it all, so she seems very comfortable with it."
Water works – "Fear is a thing that stops us living our dreams. It keeps us in our little office cubicle or in a job we're not happy with," said McNamara.
Father figure – "I had no fear of dying in big waves before I had my children. From the day I had my children I figured I had to be here for them. So I have to be prepared," said McNamara, adding: "We all have instincts we should listen to."
