The FairHelm Market Index summarises publicly visible yacht listings into model-level counts and indicative average prices — updated on a weekly cadence, not a live broker feed.
What the index measures
Each row ties a yacht model (brand + slug) to:
- Listings worldwide — count of active public listings matched to that model family at snapshot time
- Average price (EUR) — arithmetic mean of listed ask prices in EUR where currency conversion is applied consistently
- Regional splits — Sweden, Denmark and Germany when sample size allows
The index answers: “How liquid is this model right now, and what is the typical ask band?” It does not predict your negotiation outcome or replace a survey.
Data sources
| Source type | Role |
|---|---|
| Public listing portals | Primary counts and price signals |
| Normalisation rules | Model slug mapping, duplicate suppression, currency to EUR |
| Manual QA | Tier-1 models reviewed for mapping drift |
We do not ingest private broker-only inventory or paid feed APIs in this release (see deferred roadmap for live feeds).
Refresh cadence
- Weekly cron (Monday 03:00 UTC) rebuilds snapshots for tracked models
- Hub page shows latest
dateModifiedfrom the newest snapshot row - Per-model market pages link from index rows when a snapshot exists
Stale rows (zero listings after prior data) remain visible with “—” until the next successful crawl.
Limits and fair use
- Indicative only — asking prices ≠ sold prices; refit and region skew averages.
- Coverage bias — models with few listings show volatile averages; treat N<5 as directional.
- Not financial advice — use alongside survey cost planning and buyer advisory.
- AI / SEO — aggregate tables ship Dataset JSON-LD on the market index hub for citeable metrics.
