Aurora Expeditions vs Poseidon Expeditions
Choose Aurora for a 3-ship fleet with Arctic and Antarctic coverage and B Corp credentials.
Choose Poseidon for a single, smaller ship built around maximizing shore time and multiple landings a day.
| Feature | Aurora Expeditions | Poseidon Expeditions |
|---|---|---|
| Fleet | 3 vessels (Greg Mortimer, Sylvia Earle, Douglas Mawson) | 1 vessel — M/V Sea Spirit |
| Capacity | Up to ~130 | 114 passengers |
| Founded | 1991, Sydney | 1999, UK (HQ Limassol, Cyprus) |
| Hull / stabilizers | X-Bow design | Ice-strengthened hull, Rolls Royce stabilizers |
| Speed | Not verified* | 15 knots |
| Certification | B Corp; AECO founding member; IAATO member | IAATO member since 2011; AECO member |
* Aurora's cruising speed is not independently verified.
Fleet & Comfort
Aurora's three X-Bow ships spread activity across a slightly larger passenger count, up to roughly 130 guests per departure.
Poseidon runs a single ship, the M/V Sea Spirit (90.6m × 15.3m, ice-strengthened hull with Rolls Royce stabilizers, in service since May 2015), capped at 114 passengers — one of the smaller expedition-ship counts in the category.
Destinations & Access
Aurora runs Arctic and Antarctic itineraries with Zodiac-based landings.
Poseidon's priority is Antarctica, with Arctic voyages to Svalbard, Greenland, Jan Mayen, and Franz Josef Land, plus British Isles routes. Its smaller ship size means more of its passengers can go ashore per landing under IAATO group-size limits, supporting multiple landings a day.
Activities & Price
Poseidon offers sea kayaking, overnight camping in Antarctica (capped at 40 participants), Zodiac cruising, and photography-focused programming; its starting fare is not independently verified here. Aurora's published fares start at $8,427 (Spitsbergen: Realm of Ice & Wildlife, 8 days), and its comparable activity list — beyond standard Zodiac landings — is not independently verified.
Sustainability & Certification
Aurora is B Corp certified in addition to its AECO and IAATO memberships. Poseidon has been an IAATO member since 2011 and is also an AECO member, and partners with Polar Bears International, Oceanites, South Georgia Heritage Trust, and Clean Up Svalbard. Poseidon has also won International Travel Awards' Best Polar Expedition Cruise Operator title 2022–2025 and a World Travel Awards recognition in 2021.
