Launched in July 2016, the 750-passenger Seven Seas Explorer stands out as an exciting new build even in a year full of exciting new cruise ships. It’s the first new ship by Regent Seven Seas in 13 years, and certainly the first since parent company Prestige was acquired by Norwegian Cruise Line two years ago. But, perhaps most auspicious, it’s the ship that Regent has declared to be “the most luxurious ship in the world.”
