About This Score

This is a provisional score based on publicly available data only. Unlike verified yachts, this listing lacks:

  • Independent on-board inspection
  • Crew qualification verification
  • Maintenance record audit
  • Safety equipment inspection

The actual safety profile may differ significantly.

Provisional scores are calculated from eight factors: vessel age, refit recency, classification society, flag state, crew-to-guest ratio, builder reputation, vessel size, and charter region coverage. All provisional scores are capped at 75/100. Learn how scores work →
