84 Revolution By Ocean Alexander Later This Year Expect the 84R (Revolution) from American Builder Ocean Alexander later this year. This is when the yard plans to present it at the 2019 edition of the Fort Lauderdale International Boat Show (FLIBS). It was only last year at the same FLIBS that Ocean Alexander displayed the OA90R, the slightly larger sibling. There are some key differences between the two models especially regarding styling and superstructure arrangement. The window design sculpting is certainly different on both models and offer striking visual references.
