A lot of old school "warped bottom" designs used a hook to control bow rise. It works, but has other limiting factors. If you don't over power the boat, she'll likely be fine, assuming the hook is supposed to be there. If not, you can fill it with bog and paint later. They do limit top speed and can cause longitudinal instability (porpoising and other crap) if the hull is pushed too fast. Keep it below 35 MPH (56 KPH) and you'll be fine, though at 35 MPH, the hull may want to "dance", depending on weight, CG location and a number of other things.
