Antarctica21 Magellan Discoverer First Guests December 15

Antarctica21’s Magellan Discoverer is set to take its first guests on December 15, 2026, as the Chilean operator’s 2026-27 season, already under way on sister ship Magellan Explorer, moves from Patagonia into Antarctica. Cruise Industry News, citing a company update, said the newbuild will then run fly-cruises to the Antarctic Peninsula after Magellan Explorer’s November air-cruise window opens from Punta Arenas.

Travelers shopping a 2026-27 Antarctica trip now have a dated split: Magellan Explorer is already sailing, Magellan Discoverer boards in December, and the last Explorer Antarctic departures run through late March 2027. For how air-cruise and sea-voyage products differ, start with Deep Arrival’s Antarctica expedition cruise guide, then match dates to the ship you can still book.

Magellan Explorer Already Sailed From Puerto Montt

The 2026-27 program did not wait for the new hull. Magellan Explorer, the 2019 ASENAV-built sister, started the season on September 15 from Puerto Montt, according to both Cruise Industry News and Chilean broadcaster ITV Patagonia. The first block is a wilderness sea voyage through Patagonia and the Chilean fjords, not an Antarctica landing.

ITV, reporting on September 17, said passengers on that opening run would see the Gulf of Penas, the Beagle Channel, Caleta Tortel, and Pio XI Glacier, among other stops. That is a Chile-coast itinerary, useful for travelers who want sub-Antarctic scenery without the Drake Crossing or a King George Island flight. It is also the ship that will later handle Falklands, South Georgia, and Peninsula fly-cruises.

ITV put the operator’s full season at 52 confirmed expeditions. That figure is the current published load, not a daily sailing list. Anyone holding a voucher or a waitlist seat still needs the exact departure on Antarctica21’s booking page, because weather, ice, and aircraft slots can move individual dates even when the season itself is locked.

Magellan Discoverer First Guests Board December 15

Cruise Industry News said Magellan Discoverer, built at ASENAV in Valdivia, Chile, will welcome its first guests on December 15 and then run Antarctic fly-cruises. Antarctica21’s own Magellan Discoverer ship page lists the vessel as South America’s first hybrid-electric polar cruise ship, ice class PC6, 94 meters long, with hybrid-electric diesel propulsion and a 14-knot open-water speed.

Capacity on the operator’s spec sheet is up to 88 guests for air-cruises and 96 for sea voyages, with 67 expedition staff and crew. A 2024 company journal post described 40 cabins across three passenger decks, including veranda suites, family and triple cabins, and single verandas, plus an elevator serving five decks, a wet science lab, gym, sauna, and observation lounge. Treat cabin mixes as the operator’s published layout, and confirm the category you are buying on the live fare page.

The newbuild replaces Ocean Nova, which Antarctica21 had run seasonally under charter. Travelers who previously booked Ocean Nova dates should not assume the same cabin, gangway, or activity roster. Discoverer is a purpose-built sister to Explorer, not a renamed charter. CIN also noted a dedicated science lab operated with Chilean scientific institutions; that is a product detail, not a passenger science-for-credit program unless the operator later sells it that way.

Punta Arenas Fly-Cruise Window Opens in November

Starting in November, Magellan Explorer is scheduled to operate fly-cruises from King George Island in the South Shetland Islands. Guests begin in Punta Arenas, take a roughly two-hour flight to Frei Station, board the ship, and explore the South Shetlands and the western Antarctic Peninsula before flying back to Chile. CIN said the itineraries are weather-dependent and sail among icebergs when ice and wind allow.

That air-cruise pattern is Antarctica21’s core product, pioneered in 2003, and it is the reason Punta Arenas hotel nights, airport buffers, and baggage limits matter as much as the ship’s cabin. A delayed flight to King George Island can compress landings even when the vessel is already in position. Build a spare hotel night in Punta Arenas before the flight day; Deep Arrival’s Punta Arenas cruise-day guide covers what to do if the aircraft holds.

CIN said Magellan Explorer would offer Falkland Islands and South Georgia cruises from mid-October, then arrive in Antarctica in November. Those mid-October sailings are sea voyages, not the two-hour Punta Arenas hop. Do not pack for a fly-cruise if your confirmation is a Puerto Montt, Ushuaia, or Falklands embarkation. The boarding city on the invoice is the one that governs flights, visas, and transfer insurance.

Rest of the 2026-27 Calendar, Dated

Put the season on a single timeline. September 15: Explorer leaves Puerto Montt for Patagonia and the fjords. Mid-October: Explorer is scheduled for Falklands and South Georgia. November: Explorer starts King George Island fly-cruises from Punta Arenas. December 15: Discoverer takes first guests and joins the Antarctic air-cruise set. Late March 2027: Explorer’s similar Antarctic expeditions are scheduled to wrap.

ITV quoted Antarctica21 chief executive Veronica Peragallo saying the season start reflected the team’s work and guest confidence, and that Discoverer, built in Chile, would open a new stage of small-ship expeditions from Magallanes to the Antarctic Peninsula. That is the operator’s framing. The traveler decision is narrower: pick Explorer dates that already exist, or hold for Discoverer’s December 15 debut if the new hybrid ship is the point of the trip.

Magallanes region tourism officials, as cited by ITV, project about 70,000 cruise passengers and 160 port calls across the 2026-27 cruise season. That is a regional forecast, not Antarctica21’s passenger cap. Boutique ships under 100 guests still sell out on peak December and January wildlife dates, which is why the December 15 Discoverer debut is a booking event rather than a walk-up sailing.
