Annual passenger volumes on this specific segment have historically exceeded 1.5 million travelers, with vehicle deck capacity accommodating several hundred cars and trucks per sailing. Seasonal schedule adjustments typically involve reduced late-night sailings during the off-peak winter months from November to March, while daytime services largely remain consistent.
