Peter Poanessa built a great example of Devlin's Surf Scoter. There's a couple of links with pictures and details:

First is the article on Devlin's page. Next is the more detailed (and a very impressive web site also) history and picture gallery. These last are part of Mr. Poanessa's Keene Sign Worx company web page. Apparently being a sign maker is a good skill set for boat building :-)
