In 1972, McMullen sold Snark Products to Doyle Dane Bernbach (now DDB Worldwide), the world's third-largest advertising agency, keeping a two-year management tenure. DDB subsequently sold the company to San Francisco-based Kransco. Boat manufacture moved between several locations, including Virginia Beach. In 1984, Lockley purchased Snark from Kransco, merging the two companies, to be subsequently purchased by Entwistle of Hudson, MA. Entwistle manufactured the boats in New Castle, Pennsylvania. In 1996, Snark was purchased by Meyers Boat Company and production moved to Adrian, Michigan.
