After installing the hooks, I put some string on them, wrapped around the leg fairing and back to the hook. I put a little piece of tubing on the string. Now it is easy to see the affect of twisting the fairing on the leg. The training edge moves claser to one string or the other. So it is easy to get the fairing in line.
Then I moved the board all the way aft and checked. The training edge was still in between the strings.
