Winter Baltic voyage from Porvoo (Sköldvik) to the Skaw STS area off Skagen, fully inside the Baltic and North Sea SECAs. Optimised track held mean wave height of 1.03 m with a 2.68 m peak; Sea State 5+ reduced from 12.0% to 1.5%.
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 6.67% reduction is the delta sailed at the same speed band, under the same wind and wave conditions.
