The Royal Yacht Dannebrog serves as the official and private residence for the Royal Couple and other members of the Royal Family when they are on official visits overseas or on summer cruises in home waters.

The Royal Yacht Dannebrog was named by Queen Alexandrine in Copenhagen in 1931 and hoisted its flag for the first time on 26 May 1932.

Dannebrog now serves as the official and private residence for the Royal Couple and other members of the Royal Family when they are on official visits overseas or on summer cruises in home waters.

The Royal Yacht also takes part in surveillance and sea rescue operations when at sea.

Dannebrog was built in 1931-1932 at the Naval Dockyard in Copenhagen as a replacement for the previous royal vessel, the paddle steamer Dannebrog from 1879.

The ship’s hull is a riveted steel construction on transverse frames. The ship has a clipper bow and an elliptic stern. Seen from the outside, the Royal Yacht can be divided into two sections. In front of the funnel, there is space for crew accommodations, cargo and the engine. At the rear is the royal compartment, which could accommodate patients if the vessel is ever used in its role as a hospital ship. During visits to Danish and foreign ports, the covered quarterdeck is used for receptions.

Since it was commissioned in 1932, the yacht has travelled more than 300,000 nautical miles (600,000 km) and visited most of the ports of Denmark, Greenland, and the Faroe Islands. The yacht has also visited European ports, especially in France and cruised the Mediterranean and the Caribbean Seas.

A major overhaul was carried out in 1980/81 to extend the life of the yacht beyond around the start of the 21st century. Having now passed that point, the 75-year-old yacht is still in excellent condition, with major improvements including replacement of the yacht's main engines.
