# Doc Extraction Naval Architecture

## When to Use

- Extracting data from SNAME Principles of Naval Architecture (PNA)
- Processing IMO intact stability criteria (IS Code, SOLAS Ch. II-1)
- Ingesting classification society structural rules (ABS, DNV, LR, BV)
- Extracting resistance estimation data (Holtrop-Mennen, ITTC)
- Building hull form parameter databases from general arrangement plans
- Processing hydrostatic curves from stability booklets and design documents
- Mining vessel/project rudder workbooks, converted scripts, notes, and PDFs before yaw-moment or turning-trace calculations; see `references/rudder-yaw-moment-time-trace.md` for source-pack and model-boundary patterns.
