   "William Stone came from Dartmouth in Devon and set up at Hunters Point in 1853, building commercial schooners, tugs and racing yachts for a city that had existed for four years. That yard is the beginning of organised boatbuilding on the Bay as a continuous business rather than an improvisation.",
   "His son Frank moved the yard to Tiburon in the 1890s, operated briefly as Stone &amp; Swann, then as Stone &amp; Van Bergen at Harbor View in San Francisco from 1899. Frank's son Lester joined in 1911, at which point the firm took the name it kept: W. F. Stone &amp; Son. Lester became sole proprietor on his father's death in 1923 and ran the yard until he retired in 1970 — a working career of nearly sixty years.",
   "The high-water mark was <em>Northern Light</em> in 1927: a 140-foot schooner built at the estuary yard for John Borden's Arctic collecting expedition for Chicago's Field Museum, put together by forty-six men working two ten-hour shifts and finished in under a year. Latitude 38 calls her the largest schooner ever built as a sailing yacht on the West Coast.",
   "The yard built Bird boats — Nos. 12, 16, 18 and 19 in 1928–29 — YMS wooden minesweepers for the Navy in the war, and a long tail of yachts afterwards. Master shipwright Jack Ehrhorn worked there from 1941 to 1970 and again from 1987 to 2004, collaborating with Lester Stone on design as well as construction; his drawings and photographs are now two large collections at the Online Archive of California, and are the single best primary source on the yard.",
   "The Stone family sold in 1970. The business changed hands several times and finally closed in 2004 — which means that a yard founded before the Civil War survived into the era of GPS."

In 1925 they moved to Sausalito, acquiring the existing Reliance Boat and Ways Co. at Second and Main, and for the next thirty-four years the Nunes yard was the most versatile builder on the north Bay.",
   "The range is the point. In 1927 they built the 66-foot racing yawl <em>Truant</em>; in 1928 two 112-foot tuna clippers, <em>Funchal</em> and <em>Greyhound</em>; in 1929 the schooner <em>Zaca</em> for the banker Templeton Crocker, on a low bid of $350,000 — a boat later owned by Errol Flynn and restored in Brittany in the 1990s.",
   "And at the same time they built the Bear. Ernie Nunes and Marty Martinsen conceived it in 1929; the first keel went down late in 1931 and the first boat was sailing by the summer of 1932. It was 22 feet 11 inches of pine and Philippine mahogany over oak, it cost very little, and by the 1950s it was the largest one-design fleet on San Francisco Bay. Sixty-nine were built between 1932 and 1976.",
   "Ernie Nunes followed it in 1939 with the Mercury — one of the first one-designs engineered specifically for plywood — and opened a dedicated Mercury shop across the street in 1946. The main yard closed in 1959; the Mercury shop in 1962.",
   "One near-miss deserves recording. Myron Spaulding first pitched the design that became the Farallone Clipper to the Nunes brothers at about $4,900 a boat. Stephens Brothers of Stockton bid $4,750 and got the class. Three of the Bay's most consequential yards are connected by that $150."

The first Liberty ship, <em>William A. Richardson</em>, launched about six months later.",

The workforce peaked around twenty thousand across three shifts, and was integrated by both race and gender at a time when little else in American industry was.",
   "What matters here is what happened afterwards. Black employment collapsed at closure and, because of redlining, many former workers settled in the federally built Marin City rather than Sausalito itself. The emptied waterfront filled instead with surplus barges and hulls converted into houseboats — the beginning of the community Don Arques presided over.
