The UFO 31 is a pivotal design in the history of British yachting, serving as the bridge between the high-performance racing scene of the 1970s and the birth of Oyster Yachts. Designed by the esteemed firm Holman & Pye, the UFO 31 was developed as a smaller, more accessible successor to the successful UFO 34. While the hulls were predominantly molded by Colvic Craft, many were finished to a high standard by Oyster Marine or Landamores, while others were sold as kits for home completion. This heritage makes the UFO 31 a "half-tonner" with a dual identity: a formidable IOR (International Offshore Rule) racer and a robust, seaworthy coastal cruiser. Its success helped establish Richard Matthews’ fledgling company, Oyster, as a brand capable of delivering yachts that combined speed with the structural integrity required for offshore voyaging.
