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 due to their very fragile condition.

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.
