Source Policy

Luxury Ship Index treats sources as a first-class part of the editorial product. Every material specification in a published profile is tied to a source row in the canonical record, with a public URL where possible, and rendered to the reader in the article's source notes section.

Short answer

Luxury Ship Index prefers official cruise-line, shipyard and classification-society sources. Reputable industry publications are used for context and for fields that official sources do not publish. Anonymous forums, AI-generated pages, scraped travel sites and OTAs with unclear data lineage are not acceptable as factual sources.

Key claims

  • Every material ship specification is tied to a source row with a public URL where possible.
  • Official cruise-line, shipyard and classification-society sources outrank everything else.
  • Reputable industry publications fill gaps but never override official figures.
  • Anonymous forums, scraped travel sites and AI-generated pages are never used as factual sources.
  • Source URLs are rendered publicly in the article — not hidden in the CMS.

Preferred sources

Use first:

  • Official cruise-line ship pages and PDFs;
  • Official press releases and fact sheets;
  • Official deck plans;
  • Shipyard references (e.g. Meyer Werft, Fincantieri);
  • Classification society data (Lloyd's Register, RINA, DNV, ABS, Bureau Veritas);
  • Ship registry data;
  • Regulatory documents (port-state inspections, IMO records).

Secondary sources

Used to supplement official data, fill missing fields and provide context. Where a secondary source disagrees with an official one, the official figure wins:

  • Cruise Industry News;
  • Seatrade Cruise;
  • Travel Weekly;
  • Baird Maritime;
  • Other reputable maritime publications;
  • Reputable luxury travel media used for design / amenity context.

Not acceptable as factual sources

The following may inform editorial questions, but are never used as factual sources:

  • Reddit, TripAdvisor and Facebook groups;
  • YouTube comments and anonymous forums;
  • AI-generated pages or summaries;
  • Scraped travel sites and aggregators with unclear data lineage;
  • OTA pages where the underlying source is not visible.

Public source notes

Every analytical page renders a source-notes section that lists each source by name, links to its public URL where available and shows the retrieval date. Outbound links use rel="noopener"; we do not use nofollow on links to official cruise-line, shipyard, classification or reputable industry sources, because pointing to authoritative material is itself an EEAT signal.

Data conflicts

When sources disagree:

  1. Prefer the official cruise line, shipyard or classification source.
  2. Note the discrepancy if material.
  3. Do not average conflicting figures.
  4. Mark the relevant field as needing verification.
  5. Reduce the data confidence rating if the conflict affects interpretation.

Missing data

If a specification is not publicly available at the time of the last review, the field is left blank rather than estimated. Calculated metrics that depend on a missing input are themselves left null, and the affected score components fall back to a neutral value with low confidence.

Limitations

Source URLs may move, redirect or break over time. Where a source URL goes stale, the Research Desk verifies the field against an alternative official source, updates the record and logs the change in the article's changelog per the corrections policy.

Luxury Ship Index Research Desk

The Luxury Ship Index Research Desk analyses publicly available cruise line documentation, shipyard data, deck plans, reputable industry reporting and independently calculated ratios to produce plain-English technical profiles of luxury cruise ships. Research Desk articles do not invent fake human editors, fake credentials or fictional maritime careers; the byline reflects the editorial standard, not a single contributor.
