ORR Certificate Summary — Lupo Di Mare (Italia 12.98)
Rev: v1.1 · Updated: 2026-06-05
TL;DR: The 2026 ORR certificate has been submitted to the race office — treat as FINAL / valid for racing. The physical/measured numbers (boat-speed polar, sail areas, dimensions, stability) and the rating (GPH 557.1 SpM) are from the submitted cert and usable now. The one thing still gated is corrected-time / class placement against the fleet — and that waits on the 2026 fleet rating list, not on our cert: the published entry sheet carries no competitor ratings yet.

Physical / measured
These come from physical measurement and the VPP hull model. Route, plan sails, and brief crew on them.
Boat-speed polar
The cert boat-speed polar is the routing source-of-truth. See the full analysis and the loaded .pol file:
- Analysis: ../02_polars/lupo_polar_analysis.md
- Raw polar: ../02_polars/lupo_polar_raw.pol
Route offshore at S3 (~10% degradation), not at certificate (flat-water, full-crew) speeds — see ../02_polars/polar_degradation_scenarios.md.

Rating (from the submitted cert)
| Item | Value |
|---|---|
| GPH (General Purpose Handicap) | 557.1 SpM |
| Sec/mile time allowances | per submitted cert (ORR Performance Curve Scoring) |
| Class / SDL (Scoring Distance Length) assignment | per race office on the 2026 fleet list |
Still gated — but on fleet data, not our cert: corrected-time, competitor-comparison, and division/start-group analysis wait on the 2026 fleet rating list. The published entry sheet lists no competitor ratings, so "what we owe / are owed" math is not yet buildable. This is a fleet-data gap, not a draft-cert caveat.
What this cert unlocks now vs. what stays gated
| Now (usable) | Gated until the 2026 fleet rating list publishes |
|---|---|
| Route with the cert boat-speed polar (at S3) | Corrected-time / elapsed-vs-corrected analysis |
| Plan sail crossovers off measured areas | Class / division placement, start group |
| Brief crew on stability (LPS / SI) and dimensions | Rating-based competitor comparisons |
| Load polar into Expedition / Adrena | Any "what rating do we owe / are owed" math |
When the 2026 fleet list publishes with ratings, build the corrected-time/competitor analysis off it. (If the cert is ever reissued, rebuild the polar with python scripts/build_polar_from_orr.py → bash scripts/sync-polar.sh.)
