Mega Yacht Economics
Azzam (180.6m, 2013) is the world’s longest private yacht. Built for the President of UAE Khalifa bin Zayed, it cost an estimated $600M.
REV Ocean (182.9m) is technically a research vessel, not a private yacht — though built with private funds (Norwegian billionaire Kjell Inge Røkke). Sometimes counted, sometimes not.
Operating costs run 10% of build price annually. Azzam at $600M cost ~$60M/year for crew, fuel, and maintenance. Crew alone is 50-60 people.
