Methodology

How this voyage was verified

The historical AIS track was pulled from public records and matched against the master’s own reports. The VF Engine then re-routed the same vessel under the weather as it actually occurred — not a forecast. Both tracks were scored by the same FOC prediction model and compared waypoint by waypoint. The 14.34% reduction is the delta sailed at the same speed band, under the same wind and wave conditions.
