There is a brief illustrated article on surfski.info on an S&G surf ski built by a Kiwi paddler. The title is "Hayes Homebuilt".

The macho/a amongst us might also want to read the article, and especially look at the pictures, on Saturday's Wavechaser race out the Golden Gate. And while you are checking out the pictures, remember that these boats are all right around 17 inches wide and 21 feet long. On the return leg some were hitting over 13mph surfing against a strong ebb current. Yeehaw.
