Doubt it has to do with the size. I have had 2 12 footers, with differing widths, and none tried this crap. Heck, I have seen a 12 footer with a 40 Evinrude, without that problem. Occasionally, bass rockets, which ride on pad, will bow hook, but it has to do with the fact that they are 20 feet long, running at 70+ mph on a pad less than 18 inches square. Certain water conditions will do it, but even then it is very uncommon, and doesn't happen to most guys with them.
My guess is the boat that you had was damaged in some way, likely with a hull hook, which caused it to ride stupid.
