Crosstrees

India, 1888

A steel vessel reconstructed from her surviving geometry and the Underhill rig corpus. Every line is drawn from the record or generated from it — and where the study infers, it says so.

Every line has a source

India survives as geometry: a complete station model, drawn and re-drawn, kept in the study alongside the corpus that explains what was built.

The 1888 identity and her as-built dimensions come from the published Örebro I history; the rounded 32 × 6 m figure is the modern AIS listing. Her steel is recorded as user-specified, because the historical listing leaves the material field blank. The reconstruction on this page derives from the study's own source model and analysis — it is visual and preliminary engineering geometry, not a survey-grade hull surface.

These lengths describe different extents of different sources. They are not interchangeable, and the study keeps them apart:

Reconstructed hull span
30.922117 m
Historical as-built length
28.72 m
Modern AIS length
32.0 m
Source model extent
32.118429 m

Hull constants at the canonical trim — a plane 1.8 m aft to 1.5 m fore — hold for every rig: immersed volume 151.147 m³, displacement 154.925 t at 1.025 t/m³, centre of buoyancy 14.690 m from the aftmost station.

The library behind the desk

The desk does not answer from memory. It reads a knowledge base built from one book, ingested whole.

Every dimension the study asserts about masts, yards, and sails traces to Underhill's Masting and Rigging — 326 pages, 697 records, 185 figures, and 23 reviewed calculations in the authenticated library export. Where a number is proportionally inferred rather than sourced, the study says so.

Ask the drawing office

A conversation with the study itself — about the vessel, her rigs, or the corpus.

The desk answers from this study's knowledge base, cites the library as it goes, and says plainly when the evidence is missing. Rig names in an answer load that rig in the drawing above. Asking is read-only — it explains and compares, it does not change the study.
