The extreme clipper Young America, 1,961 tons, was built by William H. Webb of New York in 1853 and was his last clipper as well as his masterpiece. Constructed from the finest quality materials at a cost of $140,000, she had beautiful lines and, it was said, "was not excelled by anything afloat". Almost all her career was spent trading between San Francisco and New York or Liverpool and although not a record breaker, she made many fast or notable passages. Sold to Austrian owners in 1883 and renamed Mirolsay, she continued in the trans-Atlantic trade until 1886 when, after leaving Delaware on 17 February, she disappeared without trace or survivors.
