Between 1853 and 1970, three generations of the Stone family built more than 225 wooden boats on the shores of San Francisco Bay.  “Emerald” is one of four wooden vessels built  in 1924 by W. F. Stone & Son at Kennedy and Bocimer Streets in Oakland, California.  She is a beautiful example of old world craftsmanship and classic early 20th century naval architecture. Designed by  J. Murray Watts, she was originally built for F.A. Hyde, thought to be the vice president of Union Oil Corporation of San Francisco at that time. Now, Emerald continues to enjoy her rich ocean going history with the Challenges Foundation in Marina del Rey, California.
