Oil Canning Transom O'Day 35

[Dave Mauney]

I just noticed this evening, with the sun at the right angle, that I have oil canning in the transom associated with the back stay chain plate. The gel coat is not cracked but rumpled. Even though the tuning load that I used is well below the back stay component of the 30 degree righting moment, could this oil canning be from too tight a tuning load on the backstay? Thanks
