No, Regent and Oceania are not owned by the same company. Regent is a luxury cruise line owned and operated by Norwegian Cruise Line Holdings Ltd., while Oceania Cruises is part of Norwegian Cruise Line's Prestige Cruise Holdings subsidiary. Founded in 2002, Oceania was created to offer an upscale yet casual cruising experience that appeals to mature travelers who enjoy exotic destinations and immersive cultural experiences on board luxurious mid-sized ships. Its fleet consists of six vessels with an average age of 4 years old – among them, Marina (2010) and Riviera (2012). On the other hand, the prestigious Regent Seven Seas Cruises was founded in 1991 as RadissonSeven Seas Cruises; it offers a full-service all-inclusive cruising experience aboard its four ships: Seven Seas Voyager (2003), Seven Seas Mariner (2001), Seven Seas Navigator (1999) and Explorer(2016). It also recently launched its newest ship - The Splendor which joined their fleet earlier this year in 2020. Both brands have much to offer but they cater to different types of passengers looking for distinct experiences at sea.
