- Finding
- NARA catalogs a Department of Defense photograph titled "The medium harbor tug COSHECTON (YTM 404) remains tied to a pier, having sustained no apparent damage in the aftermath of Hurricane Hugo"; catalog production date is 1 September 1989 and location is Puerto Rico.

- 1989 catalog date
- Limitations
- Catalog metadata, not a close reading of the image. The catalog production date (1 September 1989) predates Hurricane Hugo's 18 September impact on Puerto Rico documented by NOAA (https://www.wpc.ncep.noaa.gov/tropical/rain/hugo1989.html); it cannot be accepted as the date of the described aftermath scene. The record confirms the YTM-404 designation in its title but does not establish Navy ownership in 1989, disposal date, or asbestos content.
