Bethany Hamilton, the championship surfer who lost her arm to a shark, is set to wed.

Sharing the happy news on her blog, Hamilton reveals she knew her new fiance Adam Dirks was the man for her when he agreed to jump off a cliff into the ocean with her on their first date.

She writes, "The first thing we did was jump off a cliff together!" and adds, "I know Adam and I are right for each other and that God has us together for Him. Neither of us is perfect, but in my eyes Adam is just right and I'm thankful to have someone so perfectly perfect to share life with as one."

The 23 year old, whose 2004 book inspired the 2011 movie Soul Surfer, lost her arm when she was 13.
