There where problems with intersections. Here is Quick and dirty fix. I suggest that You draw both rails (sketch1 and 11) again with splines to be sure that Your Coincident Constraint work precise.

As Leo wrote, there is a problem with intersections. I think that you should try to redesign sketches: first you need to sketch sections of the hook and then do "Project Geometry" and connect all drawn sections with the rails of the hook.
