Scaling a single axis (sketch) SW2010 / Catamaran project

I am creating a part that needs to interface to the curved perimeter of a sailboat mast. (Formula 18 catamaran!)

I actually have a physical slice of the mast extrusion, and I have scanned it with my flatbed scanner in order to traced it into a SW sketch. That worked fine. The problem is the aspect ratio of the flat bed scanner output is not 1:1, it is off by about .25%.

Solution should be simple: create the sketch per the distorted scan (done), then just scale  the sketch on a single axis to correct the error. I can not find a way to do this in SW.

Thanks for any help!
