EstimateTraffic & operations history
Traffic is not availability. Capacity is not occupancy. A reservation flag is not a live berth. EMODnet density is historical context. Forecast is deferred.
Current traffic

UNKNOWN because: AIS_NOT_CONFIGURED — congestion is not inferred from compiled peak labels.
Declared capacity
240 compiled class berths · Class counts are not physical HarborBerth rows and not current availability.
Observed occupancy
