Quick note before we start: the correct designation is HMY Britannia—Her (now His) Majesty’s Yacht—not “HMS.” She’s the last Royal Yacht, launched in 1953, commissioned in 1954, retired in 1997, and now one of Scotland’s most popular attractions in Edinburgh’s Port of Leith.

Fast Facts (Specs & Power)

  • Builder: John Brown & Co., Clydebank, Scotland (launched 16 April 1953; commissioned 11 January 1954).
  • Dimensions: length ~125.6 m (412 ft), beam ~16.8–17 m, draught ~4.6–5.2 m, gross tonnage ~5,769 GT.
  • Propulsion: two Pametrada/Parsons geared steam turbines, ~12,000 hp.
  • Speed/Range: about 21–22 knots top; roughly 2,400 nm range at cruising speed (period figures).

Service Highlights (1954–1997)

  • Served as a floating royal residence and state venue for 44 years.
  • Sailed more than 1,000,000 nautical miles, visiting 600+ ports in 135 countries, and undertaking 968 official voyages.
  • Final foreign mission: carried Governor Chris Patten and the Prince of Wales home from the 1997 Hong Kong handover; decommissioned on 11 December 1997.

Design & Interiors

  • Understated post-war design chosen by the late Queen and Prince Philip; the teak-clad Sun Lounge was Her Majesty’s favorite room.
  • The State Dining Room—the largest space aboard—can host up to 96 guests for dinner (also used as a cinema and, historically, a dance floor).
  • Crewed like a small navy: more than 200 personnel at full complement in service years.

Where Is Britannia Today?

Since 1998, HMY Britannia has been preserved as a museum ship in Leith, Edinburgh, operated by The Royal Yacht Britannia Trust. It’s repeatedly ranked among the UK’s top visitor attractions, and event spaces aboard are still used for private dinners and receptions.

Visitor Tips

  • Plan 1.5–2 hours to see the Bridge, State Apartments, crew quarters, and Engine Room. (Clocks are famously set to 3:01 pm, the time of the Queen’s final departure.)
  • If you’re hosting: the State Dining Room accommodates formal dinners; receptions can use multiple spaces depending on capacity.

Key Takeaways

  • HMY (not HMS) Britannia is the last Royal Yacht, launched 1953, commissioned 1954, retired 1997.
  • Built by John Brown & Co.; ~126 m long with steam-turbine power and ~21–22 knots speed.
  • Completed 968 official voyages and over 1 million nautical miles, visiting 135 countries.
  • Now a leading museum attraction in Leith with notable interiors like the State Dining Room (up to 96 seated).
