The FairHelm Market Index summarises publicly visible yacht listings into model-level counts and indicative average prices. Weekly cadence, not a live broker feed. Use it to shortlist Baltic liquidity, then verify with a survey.
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.
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.
- Citeable metrics - aggregate tables ship Dataset JSON-LD on the market index hub.
