Boatpedia treats specifications as cited facts with confidence, source type, unit normalization, and variant scope.

Source Confidence Ladder

Confidence rises when a fact is supported by official documents, stable class records, or repeated independent sources.
High confidence
Official builder, designer, class association, manual, brochure, or verified spec sheet.
Working confidence
Trusted catalog, review, survey note, or repeated independent source that agrees with known context.
Low confidence
Single listing, forum mention, import placeholder, or uncited inherited data.

Verification Workflow

  1. 1

    Capture the original claim

    Store the source title, URL, retrieval date, original units, and exact field context. A brochure value and a broker value should not collapse into one anonymous number.

  2. 2

    Normalize the field

    Map the value to Boatpedia measurement definitions such as LOA, beam, draft, displacement, sail area, fuel, or water capacity.

  3. 3

    Set scope

    Decide whether the fact belongs to the builder, model, variant, production band, or configuration package.

  4. 4

    Assign confidence

    Use source quality, agreement between sources, and whether the value matches the known production band.

  5. 5

    Expose uncertainty

    Show pending, variant-dependent, source-count, or last-verified states instead of presenting weak data as complete.

What Gets Stored With a Fact

FieldMeaningBoatpedia use
Fact keyStable field identity, such as dimensions.loa_m or production.year_introduced.Keeps search, API, compare, and page rendering aligned.
Value and unitOriginal and normalized measurement values.Supports metric/imperial display and formula calculations.Unit conversion should not imply more precision than the source provided.
CitationThe source document that supports the field.Lets users inspect where a claim came from.
Verification statusCurrent confidence and review state.Prevents imported or conflicting data from looking final.
