Allison R15 pad question

I am working on the bottom of my R15. This boat was set up with string steering and has been rebuilt at least once before by a P.O. so I am assuming it was raced in the past. The bottom is fairly flat for the last 3 feet, then starts to rock. One questions I have forAttachment 409895 others who may have worked on these old boats is, is that normal, or should it continue to be flat further forward? Also, the pad is completely flat at the stern, then begins to round off within just a few inches. Should it be flat further forward?

Again appologies for my photo orientation disorder. Open for suggestion as to how to correct.

Bill at the Allison Plant either knows the answer or can point you to someone that does. Call Bill @ 865-983-5920.

On the photos, when I take them with my smart phone and then transfer to my computer, most of them are turned. I flip them on my computer before saving to a file and then post from my computer. So far, the results have all been "top up". You might give that a try.....Gordon
