The Formosa yard built the Formosa
boats, the Ta Chao yard built the CT's and Transworld Boatbuilding Inc built the Transworld 41
ketch. All with more or less the same
hull. All slightly different on top and inside. The Transworld is a
center cockpit version. The Formosa yard also had a
center cockpit version of their boat. As far as I know, Transworld boatbuilding is the only yard where you can still order the boat, the CC version though. Link:

Let me know how it goes, I'm wicked curious if you can still order them.
Check out the link in my signature down below for more pictures. Ours (TW 41) is a 1979.
