The Sea Spirit is Poseidon Expeditions' intimate all-suite vessel carrying just 114 passengers, originally built in 1991 and continuously upgraded including the addition of Rolls-Royce Zero Speed Stabilizers for smoother polar navigation. Every cabin faces outward and many feature private step-out balconies — rare on a ship this size — giving guests a front-row view of Antarctic icebergs and Arctic wildlife from their own stateroom.
