When it launched in July 2016, 750-passenger Seven Seas Explorer stood out as an exciting new build even in a year that was full of exciting new cruise ships. It was the first new ship by Regent Seven Seas Cruises in 13 years, and certainly the first since parent company Prestige was acquired by Norwegian Cruise Line in 2014. But, perhaps most auspicious, it was the ship that Regent declared to be “the most luxurious ship in the world.” Since then, Seven Seas Explorer, which underwent a dry-dock refresh in May 2023, has been joined by equally luxurious sister vessels Seven Seas Splendor and Seven Seas Grandeur.
