India-to-Brazil voyage from Gujarat to Rio de Janeiro, 25 days westbound across the Indian Ocean, around the Cape of Good Hope, and across the South Atlantic. Sea State 5+ cut from 26.1% to 23.4%. Pure routing result with no ECA fuel-switching.
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 0.94% reduction is the delta sailed at the same speed band, under the same wind and wave conditions.
