Royal yachts are luxurious vessels owned by monarchs or royal families, designed for both leisure and official functions. These yachts often feature opulent interiors, advanced technology, and amenities such as swimming pools, helipads, and spacious decks. They serve as a symbol of prestige and are used for state visits, ceremonies, and private retreats. Historically, royal yachts have played significant roles in maritime tradition, showcasing the power and wealth of a nation. Notable examples include the HMY Britannia, which served the British royal family for over 40 years, and the Royal Yacht of Monaco, reflecting the unique heritage of their respective countries.
