The Jack Ehrhorn collection of Stone Boat Yard naval architectural drawings (SAFR 22826, HDC 1611) consists of 1069 naval
architectural plans, of which 176 are original drawings from the Stone Boat Yard or one of its predecessor businesses. This
collection also includes 30 document files of research and business records from Jack Ehrhorn, Stone Boat Yard, or one of
its predecessor businesses. This collection is open for use by appointment only; a small number of items are unavailable for

Company History: Stone & Swann boatyard; Stone & Van Bergen boatyard; W.F. Stone & Son boatyard; and Stone Boat Yard. Between
1853 and 1970 three generations of the Stone family built more than 225 wooden boats on the shores of San Francisco Bay. After
1970, Stone Boat Yard continued to operate until 2004 under various proprietors. Beginning in about 1937 Jack Ehrhorn (1919-2005)
was a master shipwright; he became operations foreman at the W.F. Stone & Son boatyard where he developed a reputation as
one of the west coast's premier craftsmen and builders. Jack Ehrhorn preserved the W.F. Stone & Son records that form the
core of this collection.
