Finally! A very profesionally-done website about the Flood and Noah's Ark. See: http://www.worldwideflood.com/default.htm
Scroll down to the bottom of the Home page to the article entitled, "What Noah's Ark may have looked like" and click on "More".
Also, the row of tabs along the top of the Home page also lead to all kinds of interesting information. The guy has done a lot of professional, intelligent research. A lot of the math is way over my heard.
