Looking at a 1993 53' Ocean SS. I've probably read most forum comments in existence about Oceans, and the conclusion seems to be that post 1995 Oceans are markedly better built than the prior generation boats. The 53' SS seems to have been built from 1991 - 1999. Since this was a new design, does anyone know if the 1995 version of this boat would be better built than the 1993 version, or are they identical? Also, does this boat have the fragile keel problem?
