1.2.3
- Add applied RAO gain, phase and heading-response charts for all four sailboat presets: 28, 34, 42 and 50 ft.
- Sample the production C++ transfer function directly, showing all six motion components, translation and rotation units, relative wave propagation headings, phase convention and constrained yaw.
- Include the new PNG/SVG/PGF charts in each vessel chart archive and PDF. Add viewable 28 ft previews and standalone regeneration commands in the RAO documentation.
- Preserve all five interchangeable simulation datasets and the existing vessel response equations and numerical quality gates.
The charts show the deep-water transfer-function slice, not sea-state-weighted motion spectra. The vessel presets remain estimated zero-speed analytical surrogates, not measured hull RAOs.
Tag v1.2.3 is published from the exact main commit after numerical tests, simulation audits, all five chart jobs and all nine PDF builds pass. All 24 data, chart, PDF and audit assets plus SHA256SUMS are verified before publication. Previous releases remain unchanged.
