Seabourn’s trio of sisters, each carrying 450 guests, offer a stylish and relaxed experience with lots of al fresco options, plenty of deck space, and a close connection with the sea. New slightly larger ships join the fleet in late 2016 and 2017, to extend a global range of itineraries, with short options and opportunities to combine a series of cruises to create long voyages, with inclusive fares, open dining and a laid back elegance.
