There is a new website exclusivly for the T34 C w/lots of great info, www.tca34.org
I have a T34C Yawl w/shorter 10.5' boom and mid boom sheeting. The boom was shortened early on in production, so most 34's have the 10.5 (some have retrofitted longer). The mid boom sheeting really opens up the cockpit area and works very well on the high aspect ratio main.
Love the boat. A true classic. Boats vary in states of restoration like all older boats, but in general hold value well (may even INCREASE in value, if you can believe that!) I'd be happy to answer any question.
