This boat belongs to my (distant) Uncle. I was told by him that it is a (1976?)center cockpit Columbia 40' (42' LOA).

I have dug through sailboatdata.com and all other sites that I can think of for pictures to corroborate his claim that it's a Columbia 40, however every image or line drawing of a Columbia from that vintage in the 40 foot range looks quote a bit different. Most notably they are not flush deck with a simple center cockpit.

In case it helps, while onboard about 5 or 6 years ago I snapped the following pic from under the boat with the keel somewhat visible. Since I know it probably won't show up well once the site compresses / shrinks the image, I traced the keel shape with a black line.

Does anyone have an idea what boat this really is?
