Paddle Boarders do it Standing Up

I saw a paddle board for the first time few weeks ago. I used to be keen windsurfer and we are thinking about buying a kayak so I was quite intrigued.
One came paddling into the jetty when I was there this afternoon and it turned to be Mark, an american guy I have met a few times. It looks an awkward position, standing upright on the board, and paddling along but he has explored quite a bit of the coastline and inlet on the board.
Definitely one to try when the weather warms up a bit !
