If you are shopping for a small-ship Antarctica voyage for the 2027-28 or 2028-29 season, Secret Atlas has opened a new product line on MV Aureum, a 36-guest ice-class explorer yacht built around Expedition Micro Cruises rather than a 200-passenger polar template.
The operator’s public Aureum ship page lists capacity, cabins, Zodiacs, guide ratios, and polar itineraries, while trade reporting from DRIFT Travel and Seatrade Cruise confirms the Antarpply Expeditions partnership and booking window for those two polar seasons.
The traveler decision is concrete: compare a 36-guest fly-and-cruise or South Georgia depth product against larger expedition ships before the early-booking inventory for those seasons tightens.
- What: Secret Atlas launches Antarctica and South Georgia Expedition Micro Cruises on MV Aureum.
- Capacity: 36 guests, 22 cabins, four Zodiacs, about 24 crew, 1:6 guide ratio.
- Seasons: Operator and trade sources list 2027-28 and 2028-29 polar seasons open for booking.
- Solo angle: Eight dedicated single cabins, about 36 percent of cabins, with no single supplement.
- Access modes: Fly-cruise via Puerto Natales, Chile, plus air-and-sea Drake options and South Georgia depth voyages.
What Aureum changes for polar shoppers
Most Antarctica ships still group landings in waves because they carry far more guests than a single beach or Zodiac rotation can handle at once. Aureum is sold as a different scale. Secret Atlas states a hard 36-guest ceiling, four Zodiacs, and the ability to put every guest ashore within minutes when local conditions allow.
That scale is the product, not a marketing flourish. It changes how you plan a day: fewer landing waves, less time waiting for the next boat group, and more room for the expedition team to hold a wildlife moment without a second and third rotation waiting on deck. Travelers who hate queueing for Zodiac turns will feel that difference more than travelers who mainly want a hotel-style polar cruise. Compare those priorities before you fixate on cabin square footage alone.
DRIFT Travel reports the ship will sail for Secret Atlas through a long-term partnership with Antarpply Expeditions, a company with more than 25 years of Antarctic operations. Secret Atlas itself has been known for Arctic micro-cruises since 2019. Aureum is the bridge that moves that small-group model into Antarctica and South Georgia for the first time under the Secret Atlas brand.
Co-founder Michele D’Agostino, quoted in the DRIFT report, frames the launch as an expansion of the same principles the brand used in the Arctic: small groups, deeper wildlife time, and access that larger ships cannot match. Treat the quote as brand positioning. Treat the schedule facts, cabin map, and capacity numbers as the booking data that matter.
Cabins, solos, and onboard layout
Secret Atlas lists five cabin categories on Aureum: Classic Twin, Signature Twin, Classic Single, Signature Single, and Signature Suite. Twin cabins run about 17.5 to 18 square meters. Suites on the bridge deck reach about 24.5 square meters with panoramic windows and a sitting area.
The solo story is unusually strong for polar cruising. Eight cabins are dedicated singles, split between main-deck Classic Singles with portholes and upper-deck Signature Singles with windows. The operator markets those cabins without a single supplement, which is a material price and planning difference versus lines that force solo travelers onto a full twin fare or a same-gender share.
Public spaces are organized around watching ice and wildlife rather than nightlife. The ship page highlights a bridge lounge with open-door bridge access, a forward observation deck at the bow, a lounge and restaurant sized for one sitting, and a top-deck wellness area with sauna and hot tub. Active fin stabilizers and hybrid diesel-electric propulsion with battery support are listed as comfort and noise-reduction features for open-ocean and marine-mammal waters.
Ice class is listed as 1C. That is enough for typical Antarctic Peninsula and South Georgia expedition work, not a claim of year-round heavy icebreaking. Expect routes to flex with wind, ice, and wildlife the same way other expedition products do.
How the fly-cruise and Drake options work
One of the clearest product decisions is whether you want to cross the Drake Passage by sea, skip it by air, or do one direction only.
According to DRIFT Travel and the operator itinerary pages, Secret Atlas is packaging Antarctica-by-air programs through Puerto Natales, Chile, with a charter flight of roughly two and a half hours to King George Island in the South Shetlands, where guests join Aureum. That flight can replace as much as four days of open-ocean transit on a traditional Ushuaia round trip.
Air-and-sea products keep a one-way Drake sailing and replace the return or outbound with a flight. That preserves the experience of arriving by sea for travelers who want it, while shortening total open-water days. Peninsula programs also market pushes toward the Antarctic Circle at 66 degrees 33 minutes south when ice and weather allow. Circle attainment is never guaranteed on any polar voyage, and Secret Atlas does not claim otherwise.
If you are comparing expedition products more broadly, Deep Arrival’s guide to the Douglas Mawson polar expedition ship is a useful side-by-side reference for how another small polar vessel packages capacity, decks, and expedition systems. For a second product baseline on polar decks and cabins, see the MS Expedition ship review.
South Georgia depth and combined history voyages
Aureum is not only a short Peninsula flyer product. Secret Atlas lists multi-day South Georgia depth voyages that spend more time on the island than itineraries that treat South Georgia as a brief stop on a longer Antarctica circuit. Those sailings target king penguin colonies, seals, albatrosses, and historically significant landing zones when conditions allow.
A longer combination voyage links South Georgia, Elephant Island, and the Antarctic Peninsula in a sequence tied to the Endurance expedition story. That product is for travelers who want history and wildlife on the same ticket and who can give nearly three weeks to the trip rather than a shorter fly-cruise window.
Related Deep Arrival expedition coverage already tracks the small-ship segment elsewhere, including Heritage Discoverer’s 2027 voyage slate and Aurora Expeditions’ child-age policy change. Those posts are chronology and category context, not substitutes for Aureum’s cabin and season facts.
| If you | What to do |
|---|---|
| Want Antarctica with minimal Drake time | Start with Puerto Natales fly-cruise departures and confirm charter flight timing and baggage limits. |
| Want one Drake crossing only | Compare air-and-sea one-way sail packages against full Ushuaia round trips on larger ships. |
| Travel solo and hate single supplements | Prioritize the eight dedicated single cabins before twins sell and only shared options remain. |
| Care more about South Georgia wildlife than a short Peninsula dash | Shortlist the South Georgia depth sailings rather than the shortest fly-cruise options. |
| Need circle-push attempts | Read the specific itinerary language and treat circle attainment as weather-dependent, never guaranteed. |
- Book early for singles: Only eight single cabins exist on a 36-guest ship; they are the scarce SKU.
- Match trip length to product: Fly-cruise Peninsula trips and multi-week South Georgia combinations are different calendars and budgets.
- Plan Patagonia or Ushuaia buffers: Air-cruise guests should budget hotel nights around Puerto Natales weather and charter delays.
- Compare landing group size: Use the 36-guest figure when weighing Aureum against 100-plus passenger expedition ships.
- Confirm inclusions: Zodiac boots, Wi-Fi fair-use rules, and park fees can differ by voyage; verify the exact package before deposit.
Exact published fares move by cabin and departure, so treat the operator’s live dates-and-rates pages as the source of truth for deposit amounts and cancellation windows. The durable facts for planning are capacity, season window, access modes, and the solo-cabin policy.
When does Secret Atlas sail Aureum to Antarctica?
Operator and trade sources list the 2027-28 and 2028-29 polar seasons. Check the live Secret Atlas dates page for the exact embarkation list, because individual departures can still shift while the program ramps up.
How many guests are on Aureum?
Thirty-six guests across 22 cabins, with four Zodiacs and a published 1:6 senior guide ratio. That is the core product difference versus larger expedition ships.
Can solo travelers avoid a single supplement?
Yes on the eight dedicated single cabins as marketed by Secret Atlas. Once those are gone, twin occupancy or a share may be the only remaining paths, so solos should book early.
Does the fly-cruise remove the Drake Passage completely?
On pure fly-cruise Peninsula programs that board at King George Island after a Patagonia charter, guests avoid a full round-trip Drake sailing. Air-and-sea products still include one sea crossing. Always match the itinerary code to the access mode you want.
