Call it a case of "Hang Ten x 10."

Surfer Garrett McNamara has once again gone from his Pittsfield roots to the top of world - at least when it comes to riding gigantic waves.

Thank you for all your support. It means the world to me. Today was an awesome day and so fun to be out there... fb.me/1gExz3uwz

McNamara, a native of Pittsfield, Monday reportedly broke his own world record by riding a wave estimated to be more than 100 feet high off the coast of Nazaré, Portugal. McNamara, who surfs out of Hawaii, set the current Guinness World Record for the largest wave surfed of 78-feet at Nazaré in 2011. That ride was first said to be more than 90 feet high.

No matter the official height of these waves, there's no doubt he's got some Jupiter-sized stones. McNamara moved to Hawaii with his family when he was 11. It's unlikely Bosquet Mountain or Jiminy Peak offered him much of a scare in his younger days.

A photo claiming to show McNamara riding the monster wave was taken by photographer Tó Mané (no relation to Manti Te'o) and posted on the site surfertoday.com. The photo has since gone viral on Twitter and Facebook.

Meanwhile, Portuguese surfing authorities have asked for an independent analysis to confirm the wave's height.

Radical.
