Open Questions

Designers

• Bjarne Aas
  Aas's birth and death years were not researched in this pass. Norsk Maritimt Museum drawing archive
• Donald Abbott
  No biography, dates or profession could be found. He is known only through one sentence in a class history.
• Donald Abbott
  Not to be confused with the later Sparkman & Stephens 'Weekender 24' (design 1701-C1, built 1965–77), which is a different boat.
• Hugh Angelman
  Birth and death years not found. One source names the original builder as 'Wilbo' — almost certainly a contraction of Wilmington Boat Works, but stated here as found rather than corrected.
• Colin Archer
  'Colin Archer' in a boat listing usually means the type, not the man. Farida (1960) postdates Archer's death by four decades. Norsk Maritimt Museum drawing archive
• A. M. Bellingham
  The identification with A. M. Bellingham rests on a 1936 Philippa in the WoodenBoat register credited to him, plus a brokerage listing for a sister Cooper Six-Tonner. California Digital Newspaper Collection — launch notices
• A. M. Bellingham
  The register's Philippa is recorded in British Columbia rather than San Francisco Bay; whether the Bay boat of that name is that hull or a sister is unresolved. California Digital Newspaper Collection — launch notices
• David Boyd
  Birth and death years not found.
• David Boyd
  Not to be confused with a Scottish banker and sailor of the same name who died in 2016. Norsk Maritimt Museum drawing archive
• Fred C. Brewer
  How much of the Bird belongs to Brewer's committee and how much to Alden's office is genuinely disputed between sources. This atlas does not resolve it.
• Robert Clark
  Birth and death years could not be found in any accessible source. A designer of this significance with no recorded dates is a striking gap; a Royal Institution of Naval Architects obituary would settle it.
• Harry Cookson
  No source establishes whether Cookson designed Freda as well as building her. Birth and death dates not found.
• Harry Cookson
  Freda's restoration history is well documented — Harold Sommer in the 1950s, then a fifteen-year rebuild by the Arques School culminating in her 2014 relaunch — but Cookson himself is barely recorded. California Digital Newspaper Collection — launch notices
• Harry Cookson
  Freda's description as the oldest active private sailing yacht on the West Coast is widely repeated, including by outlets independent of the Spaulding organisation, but every account appears to trace back to Spaulding and Arques School material. No register or independent body was found adjudicating the claim against rival contenders. California Digital Newspaper Collection — launch notices
• Samuel S. Crocker
  Only Crocker's role in the Bird design is sourced here. His independent career is real but was not researched in this pass — treat this entry as a stub.
• Bowdoin B. Crowninshield
  Adventuress's length is given as 133 ft by one source and 85 ft by another — probably sparred length against hull length, but not reconciled here.
• Bowdoin B. Crowninshield
  John Borden commissioned both Adventuress and, fourteen years later, Northern Light from Henry C. Grebe — a link between two boats in this atlas that has not been explored.
• Charlie Davies
  Birth year not found.
• Merle Davis
  Almost nothing about Davis is independently documented. No birth year, no firm name beyond 'yacht design office', no verified design catalogue. This is one of the clearest research gaps in the atlas.
• David W. Dickie
  No birth or death year, education, firm name or client list could be found. The genealogical placement as James S. Dickie's son rests on an OAC finding-aid note rather than a biography. For the size of the archive he left, this is the largest single biographical gap in the atlas.
• David W. Dickie
  No standalone finding aid for the drawing collection itself could be located — only the CAMM directory entry and the NPS plans page confirm it.
• Hank Easom
  Sources differ on whether the Pacific Coast Mercury Championship win was 1949 or 1950, and on the year or years of his San Francisco YC Yachtsman of the Year award.
• Hank Easom
  One profile says he was an alternate for the 1972 Olympic sailing team; this was not corroborated elsewhere. The YRA records 1947–1962 at SF Maritime
• Henry J. Gielow
  Birth and death years found in only one source and not cross-confirmed. Mystic Seaport ships plans
• Henry C. Grebe
  Birth year not found.
• Cyrus Hamlin
  Birth and death years not confirmed; an obituary gives his age at death as 98.
• Nathanael Greene Herreshoff
  Boats are often listed simply as 'Herreshoff'. That name covers at least two distinct designers — Nathanael and his son L. Francis — and also HMCo-built boats designed by others. Do not assume which is meant without checking the individual boat's documentation. MIT Museum, Hart Nautical
• George W. Kettenburg Jr.
  Sources give the yard's founding as both 1918 and 1929 — likely a 1918 founding with a 1929 rename and relocation.
• Erling Kristofersen
  An alternative designer name sometimes seen in casual sources ('Odd Borg') was checked and is a misidentification — that person is a Norwegian actor.
• A. E. 'Bill' Luders Jr.
  Design credit for Weatherly is genuinely divided between Philip Rhodes and Luders in the sources; this atlas records both. Mystic Seaport ships plans
• Ed Monk Jr.
  Birth and death dates and a verified design list were not found. Attributions to Monk Jr. of particular trawler models should be checked against a direct source.
• Ron Moore
  No birth or death year found. He may still be living, which would explain the absence of a death date, but this was not confirmed either way.
• K. Aage Nielsen
  Exact birth date not found; c. 1904 is inferred from an age of 80 at his death in June 1984. California Digital Newspaper Collection — launch notices
• Ernest 'Ernie' Nunes
  Birth and death dates not found in accessible sources. His exact relationship to the founding brothers Manuel and Antonio Nunes is described in sources only as family — confirm from Sausalito Historical Society archives before asserting it. San Francisco Maritime Research Center
• J. Parsons
  Given name not established beyond the initial.
• Josh Pryor
  Ruby's own site says she was 'designed by her Captain' without naming him in that sentence. Pryor is the only captain named anywhere on the site. The attribution is probable, not confirmed — an earlier captain cannot be ruled out.
• William J. Roué
  Roué's birth and death years were not researched in this pass.
• William 'Bill' D. Schock
  Frequently confused with Edson B. and Edson I. Schock. No source found establishes a family connection between the two Schock lines. Mystic Seaport ships plans
• Carl Schumacher
  Birth year conflicts: Latitude 38 and the National Sailing Hall of Fame give 13 June 1949; Sailing World's obituary headline gives 1951.
• Ben Seaborn
  Birth year conflicts: one account implies c. 1916, Sailboatdata gives 1920. Death year 1960 is consistent.
• Charles Sibbick
  The circumstances of his death are unclear; one account suggests drowning during an early-morning dinghy outing.
• Sparkman & Stephens
  One of the two Farallone Clipper class histories credits the design to Sparkman & Stephens; the other credits Donald Abbott. See the class entry.
• Myron Spaulding
  Birth year given as 1905 (Wikipedia) and 1906 (Sausalito Historical Society). Death year given as 2000 by most sources; at least one says 2002 — that later date more likely refers to Gladys Spaulding's death and the founding of the trust. San Francisco Maritime Research Center
• W. Frank Stone
  Birth year not found.
• W. Frank Stone
  The Golden Gate Wooden Boat Foundation gives Yankee's yard as 'the Stone Boat Yard near the Presidio'. In 1905 the firm at Harbor View was trading as Stone & Van Bergen, per Naval Marine Archive. Both descriptions point to the same place and people; the trading name is the open question. The Ehrhorn Stone Boat Yard collections
• W. Frank Stone
  Frank Stone is documented far better as a builder than as a designer. Yankee is the clearest attributed design; whether there are others is a question for the Ehrhorn drawings at the Online Archive of California. The Ehrhorn Stone Boat Yard collections
• Tord Sundén
  The authorship of the Folkboat is a genuine, unresolved dispute. This atlas records both positions and takes neither. Norsk Maritimt Museum drawing archive
• J. Murray Watts
  Not to be confused with G. L. Watson of Glasgow. Birth and death years not found. Mystic Seaport ships plans
• George H. Wayland
  The two institutional descriptions of his archive differ slightly — 721 items dated 1921–1947 in the finding aid, 725 drawings dated 1920s–1940s in the CAMM directory. Yachting on the Internet Archive
• Fenwick C. Williams
  Attribution of the Concordia yawl differs between sources — some credit Ray Hunt, one credits Williams. Not resolved here.
• Ralph E. Winslow
  One research pass found birth and death years of 1886–1957; another could not verify them. Treat as provisional. Mystic Seaport ships plans
• Bert Woollacott
  Whether Percy Vos or Woollacott built Vectis is unresolved in the New Zealand sources themselves.
• Bert Woollacott
  Region is provisional — New Zealand is not yet a region in this atlas.
• Tom Wylie
  Spelled Wylie, not Wiley. Birth year not found in accessible sources.

Builders & Yards

• American Marine Ltd. — Grand Banks
  Attributions of particular Grand Banks models to Ed Monk Jr. are commonly made but were not verified in this pass.
• Anderson & Cristofani
  Some sources describe Anderson & Cristofani as founded 'in the early 1870s'. That conflates the site's boatbuilding history with the partnership, which by those same sources' detailed chronologies did not exist under that name until 1926.
• Anderson & Cristofani
  Snark's construction is dated 1907 here and 'by 1906' in one independent account. She was building through 1906 and completed in 1907, so the two are compatible rather than contradictory.
• Arendals Yard, Gothenburg
  Folkboat production spread to many builders from 1942; early Scandinavian production yards beyond Arendals were not identified. Norsk Maritimt Museum drawing archive
• Arques Boatyard
  A 1914 photograph is captioned 'Crichton and Arques Boatyard' and one compiled list names 'Crichton & Arques' among historic Sausalito yards, but who Crichton was could not be confirmed from any institutional source. San Francisco Maritime Research Center
• Arques Boatyard
  Corrected 29 July 2026. This atlas previously implied the Arques School began at Spaulding in 2007. The school was founded in June 1996 by Bob Darr on the Arques endowment; 2007 is when it moved to the Spaulding Marine Center. San Francisco Maritime Research Center
• Børresen Bådebyggeri
  Knarr production began in Norway at the Grimsøykilen and Kilen yards before Børresen took it up; total Knarr production is given as about 450 boats. Norsk Maritimt Museum drawing archive
• Børresen Bådebyggeri
  No Folkboat production by this yard was confirmed. Norsk Maritimt Museum drawing archive
• Concordia Company
  Design credit for the Concordia yawl is given to Ray Hunt by most sources and to Fenwick Williams by at least one. This atlas records both.
• Charles Cooper
  Known only through brokerage and register listings for surviving boats. California Digital Newspaper Collection — launch notices
• Dickie Brothers / John W. Dickie & Son
  Three men in this family were called David or George Dickie and are easily conflated. The atlas separates them; the placement of David W. as James S. Dickie's son rests on a finding-aid note.
• Kneass Boat Works
  The available source gives a founding of 1868 and a founder born in 1859 — internally inconsistent. One of the two dates is wrong; the source does not say which.
• George Krenkel
  Birth and death dates not found.
• George F. Lawley & Son
  Closing year given as 1945 by one source and 1946 by another. Yachting on the Internet Archive
• George F. Lawley & Son
  Frank C. Paine is said to have taken a controlling interest in the yard from 1930. That is recorded in this atlas's Paine entry but was not corroborated in the yard histories consulted — worth confirming before it is treated as settled. MIT Museum, Hart Nautical
• Madden & Lewis Company
  Founding and closing dates were not found in accessible sources. Whether Madden & Lewis or W. F. Stone & Son built the first Bird boat is disputed between two secondary sources. San Francisco Maritime Research Center
• Marinship
  Closure is given as May 1946 by one source and shortly after the Japanese surrender in September 1945 by another. Yachting on the Internet Archive
• Marinship
  The breakdown of the 93 ships differs between two histories that agree on the total.
• Millerick Brothers
  No independent source for this firm could be found. Location, dates and principals all unknown. Worth pursuing through the Sausalito Historical Society and Latitude 38's archive. San Francisco Maritime Research Center
• Moore Sailboats
  Founding dates and principals were not researched in this pass. Stub entry.
• Henry B. Nevins, Inc.
  The Mystic Seaport finding aid for the Nevins shipyard collection returned an error when checked; the collection is believed to exist but the reference needs re-verification.
• Nunes Brothers Boat & Ways Co.
  The predecessor on the Sausalito site is now established: the Reliance Boat Company, founded by William Hynes in 1920. The name 'Dickerhoff & Nunes', which appeared in this project's original brief, remains unsupported by any source found. San Francisco Maritime Research Center
• Nunes Brothers Boat & Ways Co.
  Zaca's length is given as both 118 and 127 feet, and her launch as both 1929 and 1930. California Digital Newspaper Collection — launch notices
• Nunes Brothers Boat & Ways Co.
  Ernie Nunes's collaborator on the Bear is spelled both 'Martinsen' and 'Martinson' in different sources. San Francisco Maritime Research Center
• Okamoto Boatyard
  Nothing else about this yard could be established — no location, dates, principals or other boats. One of the most interesting gaps in the atlas.
• Menotti Pasquinucci
  The relationship between Menotti and Salvatore Pasquinucci is not established in the sources consulted.
• Quincy Adams Yacht Yard
  Founding is sharply disputed: one history has the site opening in 1906 as F. D. Lawley, Inc., closing in 1929 and reopening as Quincy Adams under Harold Noyes; another gives the Quincy Adams Yacht Yard's own span as 1932–1968. Sources also disagree on whether Fred Lawley was George Lawley's son or grandson.
• Reliance Boat & Ways Co.
  This entry resolves an earlier open question. A predecessor firm to the Nunes brothers is sometimes given as 'Dickerhoff & Nunes'; the documented predecessor on the site is the Reliance Boat Company, founded by William Hynes. San Francisco Maritime Research Center
• Richardson Bay Boatworks
  Graham Wheelock, credited with Unbearable's restoration, could not be identified further — whether he is a shipwright at the yard or an owner working there is unresolved.
• Smith and Rhuland
  End date unresolved: one source gives 1967, but a 2005 article headlined a Nova Scotia yard closure, suggesting activity continued in some form. The site is now used as a repair yard.
• Stephens Brothers Boat Builders
  Stockton is on the Delta rather than the Bay, but the Farallone Clipper is a Bay class in every other respect.
• W. F. Stone & Son / Stone Boat Yard
  Sources disagree on the yard's move dates. Naval Marine Archive gives Hunters Point 1853–1892, Tiburon 1892–99, Harbor View 1899–1911, Oakland 1911–42, Alameda 1942–2004. The OAC finding aid and Maritime Compass give slightly different years (Tiburon from 1893, Alameda from 1941). One source treats 1975 as an endpoint, which appears to mark the end of a particular ownership rather than the yard. The Ehrhorn Stone Boat Yard collections
• W. F. Stone & Son / Stone Boat Yard
  Water Witch (1928) is sometimes credited as a 'Lester Stone' design. Stone is best documented as a builder; his role as designer of individual boats should be checked against the Ehrhorn drawings. The Ehrhorn Stone Boat Yard collections
• W. F. Stone & Son / Stone Boat Yard
  The description of Northern Light as the largest schooner ever built as a sailing yacht on the West Coast, and the detail of forty-six men working two ten-hour shifts, both trace to a single lineage — Latitude 38's reporting, drawing on a 1992 WoodenBoat article. No independent source was found. Latitude 38's earlier (2004) version of the claim was broader still, 'possibly the largest sailing yacht, period'. The Ehrhorn Stone Boat Yard collections
• W. F. Stone & Son / Stone Boat Yard
  One independent shipyard history gives the founder's name as William I. Stone rather than William Stone. A minor variant, but unresolved. The Ehrhorn Stone Boat Yard collections
• Matthew Turner
  Benicia is on the Carquinez Strait rather than San Francisco Bay proper, but the yard is inseparable from Bay maritime history.
• Matthew Turner
  The frequently repeated claim that Turner was the most prolific wooden shipbuilder in American history is stronger than any independent source supports. Wikipedia hedges to 'probably never equaled in the American era of sail'; Collectors Weekly says 'more than any other U.S. shipbuilder of the late 1800s'. This atlas says 'one of the most prolific' and records the disagreement in the counts.
• Union Iron Works / Bethlehem San Francisco
  No institutional relationship — shared ownership, apprenticeship pipeline or subcontracting — between Union Iron Works and the Bay's small wooden yards was established. Labour-history and apprenticeship records, which might show individual shipwrights moving between the two worlds, were not searched.

Classes & Types

• Acorn Class
  Design year not established — the class was already sailing by April 1946 with seven boats. The YRA records 1947–1962 at SF Maritime
• Bear Class
  Dimensions differ slightly between sources: the restored Unbearable is recorded at 23'0" LOA, 6'6" beam, 3'6" draft; the NPS record for Merry Bear gives 22'9", 7'0" and 4'0". Plausible given amateur and semi-custom construction, but not reconciled.
• Bear Class
  Velerosa is listed elsewhere as hull #69 with a 1978 date, which sits just outside the 1932–1976 build span given by the class association.
• Bear Class
  The claims that the Bear was the largest one-design fleet on San Francisco Bay by the late 1950s, and that it peaked near 65 boats in the 1960s, come from the class association and a closely related site. The 69-hull total is independently corroborated; the superlative is not, and was not tested against the Bird, Folkboat or El Toro fleets of the same years. Norsk Maritimt Museum drawing archive
• Bird Class
  The specific attribution — Alden design No. 157, drawn by Sam Crocker, dated 1 September 1921 — rests on a single enthusiast blog and an aggregator that appears to draw on it. Neither Alden's published biography nor the MIT Museum's Alden collection was found to corroborate the design number or the date. Treat it as the best available account rather than an established fact; the MIT Alden collection would settle it. MIT Museum, Hart Nautical
• Bird Class
  First-built year is given as 1921, 1922 and 1923 by different sources.
• Bird Class
  The builder of boat No. 1 (Osprey) is given as Madden & Lewis of Sausalito by one source and W. F. Stone & Son of Oakland by another. San Francisco Maritime Research Center
• Bird Class
  Total hulls built is given as 24 by one source and 30 by another.
• The Colin Archer Type
  'Colin Archer' in a listing almost always denotes a type rather than a boat from Archer's yard. Norsk Maritimt Museum drawing archive
• Cooper Six-Tonner
  The connection to Philippa is probable rather than confirmed — see the Bellingham entry.
• El Toro
  The designer of the parent Sabot pram is given in one source as 'Charles MacGregor' or 'McGregor' — the spelling was not resolved.
• El Toro
  The detail of ninety-five skippers meeting at Richmond Yacht Club in April 1946 to elect Hal Decker as first class chairman appears only on the class association's own history page. The origin story and the 11,000-plus total are independently corroborated. Yachting on the Internet Archive
• Farallone Clipper
  Largely reconciled 29 July 2026. The two rival accounts are compatible. The class history's exact words are 'the 1937 Donald Abbott-sponsored, Sparkman & Stephens-designed Weekender' — so Abbott commissioned the boat, Sparkman & Stephens designed it, and Stephens Brothers stretched it to 38 feet. Earlier readings of the same sentence turned Abbott into the designer. The remaining uncertainty is how much Stephens Brothers changed.
• Farallone Clipper
  Number built: 'at least 16, with only five more after 1958' by one account; 19 by another. California Digital Newspaper Collection — launch notices
• Farallone Clipper
  Build span: 1938 with racing from 1939 by one account; 1940–1962 by another.
• Farallone Clipper
  Spelling: a 1954 San Francisco Chronicle listing uses 'Farallon Clipper'; the class sites use 'Farallone'. California Digital Newspaper Collection — launch notices
• Farallone Clipper
  The bidding story — Spaulding pitching the design to Nunes Brothers at about $4,900 a boat against Stephens Brothers' $4,750 — appears only on the class's own websites. No independent source was found. It is a good story and may well be true; it is not corroborated. San Francisco Maritime Research Center
• Hurricane 30
  Everything in this entry rests on a single owner-submitted record in the WoodenBoat Register. No other source for the class — hull count, builder, the Lipton trophy years, or Random's earlier names — could be found anywhere. It is recorded here because it is the only account there is, and flagged because that is a fragile basis for a class entry. California Digital Newspaper Collection — launch notices
• Hurricane 30
  No individual naval architect could be confirmed for the class. Whether Ernie Nunes designed it, as he did the Bear and the Mercury, is a reasonable hypothesis but is not sourced. San Francisco Maritime Research Center
• Hurricane 30
  The class is named in a 1954 San Francisco Chronicle roundup of Bay one-designs and then effectively disappears from the literature. California Digital Newspaper Collection — launch notices
• International One Design
  Corrected 29 July 2026. This entry previously said San Francisco hosted the 1965 Worlds and that Wosser won in 1966. The International One Design World Championship list records 1965 at Bermuda, no championship held in 1966, and San Francisco hosting in 1969 and 1973. The error came from compressing a class history that named Wosser's wins without their venues.
• International One Design
  The Bay fleet's founding details — Lon Price, Norena #75 in 1952, YRA Fleet #4 from 1955 — rest on the class association's own history and were not independently corroborated.
• Junior Clipper
  A April 1946 Yachting item describes a 'Baby Clipper Class, designed and built by Stephens Brothers… a plywood sloop, a little over 20 ft in length'. Whether that is an early prototype of the Junior Clipper under a working name, or a genuinely separate smaller class, is unresolved — the lengths differ by six feet. The YRA records 1947–1962 at SF Maritime
• Junior Clipper
  No designer of record was found. Stephens Brothers is credited as builder; whether the design came from within the yard is not established. The YRA records 1947–1962 at SF Maritime
• Mercury 18
  Two unrelated classes share the name Mercury, both dating from 1939. The West Coast boat is the Nunes-designed Mercury 18. The other is a 15-ft Sparkman & Stephens junior boat built by Cape Cod Shipbuilding in Massachusetts. They must not be conflated. San Francisco Maritime Research Center
• Mercury 18
  First-build year is given as both 1938 and 1939 in different sources.
• Nordic Folkboat
  Sundén's claim to sole authorship was disputed by the sponsoring committee and was never formally resolved. He pursued it until his death in 1999. Norsk Maritimt Museum drawing archive
• P.I.C. Class
  No designer or builder was recovered despite searching Yachting from 1936 to the mid-1950s. That the P.I.C. and the Bird share a sponsor in the P.I.Y.A. is suggestive but proves nothing about authorship. Yachting on the Internet Archive
• Windward Class
  Builder of the Bay boats not established. The YRA records 1947–1962 at SF Maritime
• Yankee One Design
  The Bay-specific detail — that Flotsam is Y42, the last of the class, built by John Linderman at Stone Boat Yard in Alameda — rests on the WoodenBoat Register and Sailboatdata alone. The general class facts are corroborated across several independent listings. California Digital Newspaper Collection — launch notices
• Yankee One Design
  Hull counts differ: 42 built 1937–1963 by one account, 39 built 1937–2010 by the class's own site.
• Yankee One Design
  Flame (1949) is sometimes credited to 'Herreshoff, Burgess, Paine'. She is a Yankee One Design. The three-name credit is best explained by the composition of Burgess's Boston office at the time — W. Starling Burgess in partnership with Frank Paine and A. Loring Swasey, with L. Francis Herreshoff on the payroll — so the whole office was credited rather than Burgess alone. This is a reasoned explanation, not a documented one. MIT Museum, Hart Nautical

Associations & Institutions

• Golden Gate Wooden Boat Foundation
  Founding date not yet established.
• Herreshoff Marine Museum
  This atlas previously said MIT holds all Herreshoff Manufacturing Company construction drawings. MIT describes its 17,000-object Haffenreffer-Herreshoff collection as the primary design record of the company, but no source asserts exclusivity. Softened 29 July 2026. MIT Museum, Hart Nautical
• Master Mariners Benevolent Association
  No source gives an exact year for the renaming from Boatmen's Protective Association to Master Mariners Benevolent Association beyond 'after 1869'.
• Spaulding Marine Center
  'The Sausalito Wooden Boat Show' is ambiguous in casual usage. It may mean the Master Mariners Wooden Boat Show at Corinthian YC in Tiburon, or the newer Sausalito Boat Show run by Spaulding since 2023. No source unifies them. San Francisco Maritime Research Center
• WoodenBoat
  The WoodenBoat School's founding year is unconfirmed here.

Vessels

• Adventuress
  Length is given as 133 ft by one source and 85 ft by another — probably sparred against hull length, not reconciled here.
• Freda
  Whether Cookson designed her as well as building her is not established.
• Freda
  The claim that she is the oldest active private sailing yacht on the West Coast is widely repeated but was never independently adjudicated against rival claimants; every account appears to trace to Spaulding and Arques material. San Francisco Maritime Research Center
• Northern Light
  The 'largest schooner built as a sailing yacht on the West Coast' claim and the 46-men detail both trace to a single lineage — Latitude 38's reporting, drawing on a 1992 WoodenBoat article. An earlier version of the same claim was broader still.
• Northern Light
  Her later history has not been researched here.
• Yankee
  The Foundation names the yard as 'the Stone Boat Yard near the Presidio'; the firm was trading at Harbor View as Stone & Van Bergen in 1905 per Naval Marine Archive. Same place and people; the trading name is unresolved. The Ehrhorn Stone Boat Yard collections
• Yankee
  The 1962 film is not named in the source consulted and is not asserted here.
• Zaca
  Length is given as both 118 and 127 feet, and her launch as both 1929 and 1930. California Digital Newspaper Collection — launch notices

If you can answer one of these

A claim plus a source is all it takes — and the source need not be an archive. A class newsletter, a builder's plaque, a photograph with a date on the back, or your own first-hand knowledge clearly identified as such are all welcome. See Contribute, or write to corrections@ggwbf.org.
