Tom,
I have hull #124, have only had her since last November and am really enjoying learning the boat, traded up from a Pearson 30. I do not have any specs on the rig tension, just have used experience and feel and she seems to be tuned ok, raced yesterday we beat a Gulfstar 41 and a Hunter 42. it was an interesting race, two clubs sailing together but scoring seperately. We had a total of 13 boats out; in our class a Catalina 36 and a J-28 beat us.
I'd like to stay in touch, there are not many of the 34T's around. I'm located on the north side of lake Pontchartrain from New Orleans.
