Am looking at possibly buying an '82 Oday 28. Have read some sterling reviews of the '83 model and was wondering what the differences in the model years might be, if any. I am just starting this so, from quick review of this site, I believe there are different keel/cb models. The one I am looking at is keel only, and the owner says "iron keel," if that narrows anything down. The boat looks clean but I was particularly taken by one owner's writing about how the main shrouds went to glass only. Having almost bought an older C&C that ended up having some early rot in its bulkheads where the chainplates went I am now sensitized to that issue. So I'd ask whether the '82 28's had the glass only insertions. Will likely need to replace the diesel and was also wondering if anyone knew of places I could find a refurbed or used one. Any info would be appreciated. ThanksSteve
