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 →
