About a year ago, I was approached by a guy that wanted me to make him some wake surf "skis". I thought it was a bit intriguing, so I helped him build a prototype with 2lb EPS. He wanted to keep things on the down low back then, but is ready to share.
He has since found a local shaper back east and they have been building StandUp paddle Skis as well -- footage surfing some big waves in Hawaii coming soon. Jason (the mastermind) is a stand up guy and I wish him the best!
Here are a few build pics and a some video as well: http://www.youtube.com/watch?v=_tUL-V7lmBc
