I have a Z-7 that has the hooked hull and I'm goin to try and fix it but would like to know from others with a known good hull. Is it completely flat all the way back to the transom?? Any pics with a straight edge from the transom forward would be great. It seems to have more the farther out it goes. Not sure if that's built into the hull or if it's supposed to be flat too. Thanks for any help I can get!!
