I know from considering the Tartan 34c as well at some time in the past that this boat enjoys an AMAZING owners association. http://www.tartanowners.org/models/t34profile.phtml
is just 1 link I dragged up.
There is actually a T34 yearbook that circulates anually, and it is a peice of work let me tell you! Glossy pages, articles, restoration projects. On the chesapeake they are a very popular boat, handsome, well found, and would (I bet) be a pleasure to own. Having been aboard a few the access points to almost all the mechanical systems are very convenient.
