Rick,

I measured my Wave and found there was about a 3/4" difference in the measurement between the bows and sterns, the Bow measurement was less. What kind of "stoppers" did your son use and how did he fasten them on?

I made some "shims" that fit between the stopper on the forward cross member and the hulls, and tried some double sided tap to hold them in. It didn't matter if I fastened them to the hull or the stopper, they always shifted, so I removed them.

So I'd like to hear how you did it.
