About the TRINTELLA IIIA
In the UK, a number of yachts to this design (molded by Tyler Boat Co.) were finished by Frank Halls & Son. Another version, finished by Offshore Yachts (UK) was sold as the OFFSHORE T35. Besides the TRINTELLA IIIA, it is thought that at least 100 more were built. See Mike Davies book,'Essex and Suffolk Boatyards & Boat Builders. Thanks also to the Trintella Friends Association for assistance.
