Departing Tubarão on the Brazilian east coast, the vessel tracked north-east along the Brazilian bulge before turning north-west after the equator, transiting the Caribbean Sea and approaching the Gulf of Mexico via the Yucatan Channel. Mean wave height 1.69 m; 80.2% of waypoints Sea State 4+ vs 80.4% on the historical replay.
How the voyage performed across wave height and Douglas Sea State exposure — recorded waypoint-by-waypoint.
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 13.67% reduction is the delta sailed at the same speed band, under the same wind and wave conditions.
