Bethany Hamilton has ridden 40-foot waves at Jaws, in Hawaii, seven months after giving birth to her son Tobias.

Twelve years after losing her left arm in a tiger shark attack at Tunnels Beach, Kauai, Hamilton says he caught the biggest wave of her life and career in Peahi's infamous surf break.

The 25-year-old surf star was towed into huge waves, as her husband and father watched from a boat. It was not her debut at Jaws. Bethany Hamilton surfed a single wave here when she was just 18.

"I've always had a passion for surfing big waves and pushing my ability and today that's what I got to do. It's an amazing feeling to be surrounded by people I love, who support and believe in my ability," Hamilton wrote.

"Huge mahalos to my hubby, dad, babysitter and everyone in the water. I'm beyond stoked and so very thankful! I just got the heaviest, biggest wave of my life."

The Hawaiian goofy-footer has been training to get back in shape since Tobias was born. She is also shooting "Surfs Like a Girl," a biopic that documents her incredible life story.
