From Tayana 37 newsgroup: Bob Berg (the real creator of the Tayana 37 and the creator of the BaBa boats) took his preliminary ideas to Bob Perry, who then did the formal design.). Mr. C.T. Chen of the Ta Chiao Bros., Taiwan, had been building a series of CT sailboats of various sizes. He asked Bob Perry to design a 37 footer for him. Bob Berg and Will Eckert, partners in Flying Dutchman Yachts, Seattle, worked with Perry on some of the basics. A picture of Hull #1 (the hull was used to make the mold for Tayana boats) appeared on the cover of Sea Magazine in 1975. Mr. Chen did not believe the "CT 37" would be a success so he gave the design rights to Ta Yang in exchange for a 10 interest in the boat.
The CT 34 hull is solid core (and thick) fiberglass with encapsulated keel (probably iron cast in concrete). The decks are about 5/8" thick with 1/8" fiberglass encapsulating a solid wood core on both sides. The Top of the cabin house is solid fiberglass, and the sides are about 1" thick with plywood encapsulated in 1/8" fiberglass on both sides. When the boat was hauled after purchase, there was no evidence of any blistering. All bronze seacocks were inspected and found to be in excellent condition.
From Julia Chen, Business Section, Ta Chiao, March 25, 2002:
We designed and started to build the CT-34 from early 1970, and then stopped this line in 1987 after building 43 vessels.
