Data Sources
Each figure on a True Fathom screen, report or export traces back to a named source below - a public regulator, an open dataset or our own measurement. No anonymised aggregators, no "proprietary feed".
Designations are sourced from each issuing authority's own publication, not from a re-packaged aggregator, so the provenance on a hit is the regulator itself.

Licence terms above are indicative and summarise each issuer's published posture; the authoritative, per-source licence register is maintained internally and governs what may be redistributed. Sources are added and refreshed continuously, so coverage of any single list reflects its current onboarding state.
Every value is fetched into a raw archive first, refined into our schema, then scored - and it keeps a provenance block all the way through, so the source, fetch time and confidence travel with the field onto the screen and into every PDF and Excel export.

}How those inputs are weighted into a score is on the methodology page; live coverage and freshness per source is on data accuracy.
The free tier gives you one vessel screen a month, every field carrying the source it came from.
