- DANFS records for this hull, verbatim: 'Built at Quincy Adams Yacht Yard, Quincy, Mass. Keel laid 9/3/41. Launched 4/27/42. Commissioned 5/14/42. Change from SC-629 to SCC-629 on 8/20/45. Transferred to Maritime Commission 3/8/49.' The entry is a one-line milestone record with no service narrative - it does not carry the PC-629 commissioning designation, the April 1943 reclassification, decommission/strike dates, or any operational detail.

- NavSource is a volunteer secondary compilation, not a primary registry - its milestone dates track DANFS where DANFS covers them, and the commissioning designation (PC-629), April 1943 reclassification month, decommission/strike dates, the entire commercial-ownership chain, the 1972 foundering, the call sign, CO list, and spec block come from this source alone among those searched. Its 'no DANFS history' note is stale - the one-line DANFS entry exists (ev-01). Contains no asbestos content.

- NavSource 12/01idx.htm class introduction paragraph and PC-461-class series list
- Finding type
- vessel_history
- Finding
- CORRECTION / designation-chain support: the class index explains the PC-629 -> SC-629 reclassification as class-wide, not hull-unique - 'World War II expansion programs led to construction of two large groups of subchasers, the new 110-foot wooden-hulled craft and the 173-foot steel-hulled type. By 1943, it was felt desirable to differentiate between the two types. The type symbol PC was retained for the steel 173-footers, and the separate symbol SC was adopted for the 110-foot vessels. These now dropped the dual "S.C.-PC" identification, and were simply identified as "USS SC-."' The same index lists the steel PC-461-class build series as PC-461 to PC-496, PC-542 to PC-627, PC-776 to PC-826, and PC-1077 to PC-1265 - the 629 number falls outside every steel-PC series. This hull was therefore never a PC-461-class steel patrol craft: PC-629 was the shared-series number carried by a wooden 110' boat until the April 1943 re-symboling.

- Corrects the batch-scope risk of reading 'PC-629' as a PC-461-class vessel - it is a designation-history fact, not a material claim. The 1943 dual-to-SC re-symboling is stated at class level; this hull's specific April 1943 reclassification month rests on the vessel page (ev-02). No asbestos content.

- The builder's-yard table records for this hull: 'SC 629 | US Navy | Sub Chaser | 136d | 110 | 14-May-42 | Later SCC 629, to the NDRF 1949' - corroborating the 14 May 1942 delivery/commissioning date and the 1949 government custody transfer. The companion production table lists 'SC-629 | Quincy Adams YY | Quincy MA | 148 | 110 | 14 May 1942 | to MARAD 1949.' The yard page documents Quincy Adams Yacht Yard as founded 1906 by Fred Lawley as F. D. Lawley, Inc., failed 1929, sold to Harold Noyes and renamed; located at 47 Palmer Street, Germantown, Quincy; the site is now the Clipper Marina condos. The same table lists 24 Navy subchasers built at this yard (SC 513, SC 514, SC 628-629, SC 744-750, SC 1266-1275, SC 1474-1479).

- Limitations
- Shipbuildinghistory is a long-running secondary reference compilation (yard records and delivery tables), not an official registry - it corroborates DANFS/NavSource milestones but adds no unique hull facts beyond the NDRF-wording of the 1949 transfer. Its tonnage convention (136d tons in the yard table, 148 in the production table) differs from NavSource's spec block (110 t.) - a standard-vs-loaded displacement variance noted in gaps. No asbestos content.

[6]Era inference built on: NARA-authored Unwritten Record blog (wooden 110' SC put into production for WWII); NavSource spec block (GM 8-268A diesels, no steam plant); class-article construction data (438 boats, 1941-44); GAO HRD-80-2 Navy asbestos-era documentation (ev-08) [other_primary]

- Finding type
- asbestos_application
- Finding
- A wooden-hulled, diesel-powered 110' submarine chaser built 1941-42 sits inside the Navy's documented asbestos-use era but at the low end of its material intensity: no boilers, no steam lines, no turbine lagging - the dominant shipboard asbestos pathways do not exist on this hull type. Era-standard diesel-craft applications aboard a boat of this type and period were engine and exhaust lagging, machinery gaskets, valve packing, and electrical/wiring insulation in a small wooden hull volume.

The wooden-hull type plausibly carried materially less asbestos than steel steam vessels of the same era - an inference about degree, not an exemption claim. No manufacturer attribution for this hull.

- NARA-authored record on the type: '440 of these wooden SC boats were constructed and placed in service during the World War I era. The design proved very effective, and an improved wooden 110' SC was put into production for World War II' - confirming the wooden-hull construction of this hull's class from a government archival source, and pointing to RG 19 Alphabetical Series of Ship Engineering Drawings holdings for the 110' chaser type (NAID 28264940 outboard profile; NAID 30010079).

- Finding type
- gov_survey
- Finding
- GAO's review of Navy asbestos-exposure protection documented that asbestos insulation was in use in Navy ships, and that the Navy's 1975 policy was to remove and replace with nonasbestos materials only insulation that was damaged or had to be removed for repairs - a policy modified in 1979 to selective replacement in high-maintenance areas. The program-level finding places asbestos insulation aboard Navy ships throughout this hull's U.S. service era (1942-46) and well after.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming USS SC-629 / PC-629 / SCC-629 / Buccaneer was found in the public sources searched. CourtListener 'SC-629' opinion search returned 69 results - all name collisions (state reporter citations containing 'S.C. 629'/'SC-629' strings, e.g., Kentucky, Georgia, Alabama, Missouri, Indiana appellate reports; none referencing the vessel); the 'SC-629' docket search returned 15 results - all collisions (bankruptcy and civil dockets with matching strings; none referencing the vessel). CAVEAT: both 'SC 629' variant queries (opinion and docket) could not be run this session - the fleet-wide CourtListener pacing budget stayed saturated through spaced retries (helper stand-down guidance obeyed); logged 'blocked' in search_ledger, not as negative results. No asbestos-qualified variant was run - with the opinion base returning collisions-only noise on this string, the variant is permitted but was not prioritized against the contended pacing budget. Secondary web sweeps surfaced no qualifying case and no asbestos content naming this hull, the Quincy Adams yard, or the Buccaneer.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 110' wooden diesel boat simply has few asbestos-relevant systems and generated few paper records; no survey would be expected for a hull this small disposed of in 1949. The litigation search is genuinely open on the 'SC 629' string variant (pacing-blocked, not run) and on the PC-629/SCC-629 designation variants (not run - see search_ledger note). RG 24 deck logs (1942-46) are undigitized/open leads. Does not establish or defeat any claim of exposure or legal eligibility.
