interesting
At first glance, it looked funny, espeically in the picture it was being used in because it didn't look like much wind and I was wondering why the guy would want to dump air. After reading from that link, I realized the "Wing" adds lift to the bow instead of pulling down on the mast. I wonder if it works as good as theory. That lift, if it works, will help in large waves reduce the risk of pitch poling and also create a more smooth ride which may increase forward motion (less up and down countering the forward motion). I'm very curious if it works.
