According to http://www.columbia-yachts.com/c-34m2.html there was a CB model for the 34.2 (not 34.1 as I mistyped) It was mentioned in early brochures and was replaced by the shoal draft in brochures later in production. Whether there were very many of either built I couldn't say.
Yup. I had the SD version but changed it to the CB version. But I added it back and now I have all 3.
The error was that I used the used the same ballast and displ figures of the CB /SD versions for the fixed keel version. (now corrected)
The one I was commenting about was the third link in your message which takes you to the COLUMBIA 43. (corrections to be made for this boat also). So I think that all the errors you have pointed out have been corrected. (actually, I haven't got around to changing the PSC 40 yet, will soon)
At any rate, it was very helpful. Like to get the numbers right.
