I got a few more articles like that go to :
http://www.geocities.com/kustzeilen/and scroll down
Especially the article by Tom Speer, Jim Boyer and the article by Bethwaite about the 49-er are interesting. And lets not forget JSD with "Airfoils and airflow"
In the future I hope to update the page with several more links to interesting articles.
Have fun.
