Frederik IX (definitive issue): "As crown prince he broke with a long tradition in the royal family by training with the navy instead of the army, and he became the first king since Christian IV (1577-1648) who could sail a ship. His long career as a naval officer came to influence his style as king to a high degree". (Amalienborg, Copenhagen, 2024)
