His Majesty’s Yacht Omega was originally constructed for naval service at the Admiralty's Devonport Dockyard during World War I. Following the conclusion of the war, she was employed as a patrol boat during the Schneider Trophy Races held at Spithead from 1929 to 1931. During this period, British entries won the trophy outright each year.

Subsequently, Omega was sold to Mr. A.C. Foreman, who owned the vessel for twenty-three years. During World War II, the Admiralty requisitioned her for the Dunkirk evacuation. Afterward, she continued naval service on East Coast patrol duties, later serving as a barrage-balloon vessel and finally as an accommodation vessel. Prior to being returned to Mr. Foreman, the Admiralty undertook a comprehensive reconditioning of the yacht.

Omega is a substantial ketch-rigged yacht featuring a straight stem and an elliptical stern. She is carvel-built and powered by a 68hp Gardner diesel engine.

In 1985, Mr. and Mrs. Rouse acquired Omega. They maintain her at the Severn Motor Yacht Club, Clerkenleap, Worcester. The yacht is also a member of the Association of Dunkirk Little Ships.
