The reincarnation of a venerable British line that was founded in the 1950s when two men with the surname Swan began chartering ships to take well-educated British passengers to the Greek Islands, the new Swan Hellenic (reborn in 2020) has its sights firmly set on polar adventure. Its three luxury expedition ships — SH Minerva, SH Vega, and SH Diana — feature Scandinavian-inspired design, accommodate 152 to 192 guests, and cruise Antarctica and the Arctic in season (winter and summer, respectively) and more accessible destinations such as Africa, Central America & the Caribbean, Canada, and the Mediterranean in between.
