A Luxury Yacht (also called super yacht, large yacht and mega yacht) is a very expensive, privately owned, and professionally crewed sailing or motor yacht.
Bryan Mills got into a car chase with Ali and jumped onto the yacht that Raman owned, that headed down the Seine. Bryan killed all seven of Raman's security guards and finished by getting into a violent knife fight with Ali, which killed him. Bryan then took Ali's Taurus PT145 Millenium Pro Pistol and went into Raman's Bedroom where he saw Raman holding a knife to Kim's throat. Bryan aimed his gun at Raman's head and Raman attempted to negotiate only for Bryan to shoot him in the head anyway, and got Kim back.
