Seven Seas Explorer is the lead vessel of Regent Seven Seas Cruises' Explorer class, delivered by Italy's Fincantieri in 2016 and famously marketed at launch as 'the most luxurious ship ever built.' A compact 55,254-gross-ton ship carrying just 750 guests with a crew of around 550, she is entirely all-suite and all-balcony, with every stateroom featuring a private veranda. Her fully all-inclusive fare covers fine dining, shore excursions, beverages and gratuities, positioning her at the top end of the ultra-luxury market.
