Here is a pic that shows that the blade extends about 3/4" to 1" below the bottom of the hull. this was modeled after the NSS that does the same thing.

(this pic is before we cleaned up the edges and smoothed everything out)


Also, I added lines to the Starboard side too. This one extends 3" out laterally. In this pic, the edges were cleaned up nicely and it's in it's finished configuration. Next step is to water test.
