Donald McKay, named after her designer, was built for James Baines & Co. She was the last extreme clipper ship built by Donald McKay. Donald McKay sailed on the Black Ball Line of Liverpool from 1855 to 1868, carrying passengers and mail between England and Australia.
Donald McKay was launched on Donald McKay's shipyard in East Boston, USA, in January 1855. Newspapers reported that she had "all the airy beauty of a clipper combined with the stately outline of a ship of war and, though not sharp, yet her great length, buoyancy, and stability, indicate[d] that she [would] sail very fast, and be an excellent sea boat". Her passenger capacity was reported at 591 plus crew.
