Data Confidence & Provenance Intelligence

Understand what Superyacht Guide knows, what the evidence supports, what is reported, what is estimated and where evidence remains limited.

There is no single yacht “accuracy score”. Confidence belongs to individual facts and data categories. The same yacht can have a source-backed identity, strong technical records, an estimated valuation, low-confidence ownership reporting and verified documentary operating-cost evidence at the same time.

How confidence is classified

VERIFIED

Strong documentary or primary evidence, used only where the evidence type supports that description.

SOURCE-BACKED

Attributable evidence supports the record, without implying every individual field has been independently verified.

REPORTED / ESTIMATED

Publicly reported information or an editorial, market or modelled estimate rather than a verified legal or transaction fact.

LIMITED / CONFLICTING / UNKNOWN

Evidence is sparse, uncertain, disputed, conflicting or not currently sufficient.

Provenance profile

Sirena Marine · 42.23 m

0 record-level sources

Existing record verification: Source review pending · Not yet assessed
This existing record-level assessment is separate from the dimensional analysis below.

Identity

LIMITED EVIDENCE

Identity data is recorded, but no YachtSource evidence is attached to the public record.

Evidence: Confidence not assessed

Record-level sources may support several profile fields. A source count does not mean every individual field has been independently verified.

Technical data

LIMITED EVIDENCE

7 technical data areas are populated, but no YachtSource evidence is attached.

Evidence: Confidence not assessed

Technical confidence is conservative because existing YachtSource records are often record-level rather than mapped one-to-one to every technical field.

Build / project status

Important: More sources do not automatically mean a fact is more accurate. One authoritative primary document can be stronger than many derivative articles. Source count, source quality, recency, conflicts and whether a figure is reported, estimated or documented must all be considered together.
