Antarctica21 adds 88-guest ship to Antarctic air-cruise inventory

By Elena Vasquez

Magellan Discoverer can carry up to 88 guests when its first Antarctic air-cruise departs December 15, adding a 40-cabin vessel to Antarctica21’s two-ship lineup for the 2026–27 season.

Antarctica21 christened the new expedition ship in Punta Arenas, Chile, on Friday, November 6. It bills the vessel as the first hybrid-electric ship, combining battery and engine power, with azimuthal propulsion—rotating pod-mounted thrusters—built in the Americas. That “first” designation is the operator’s claim; the announcement provides no independent certification or comparative vessel list.

Magellan Discoverer has 40 cabins, each with a private balcony, and can carry a maximum of 88 guests on Antarctic air-cruises, supported by an expedition team and 67 crew. Single-setting dining serves Chilean-inspired menus and Chilean wines. Other features include a 360-degree walking deck, an accessible bow and a sauna with wide windows; Tomas Tillberg Design created the interiors.

What does the launch change for travel sellers?

For sellers, the launch expands bookable inventory but does not yet establish demand. The announcement discloses no sailing count, booking tally, fare, occupancy rate or commission structure, so it cannot support a forecast of revenue or market-share gain.

That absence matters. Antarctica21 says air-cruises on both Magellan Discoverer and Magellan Explorer are on sale through the 2028–29 season, giving intermediaries a multi-season window to sell the vessels. Availability is not occupancy. Actual pricing and take-up will determine whether the added ship changes Antarctica21’s revenue or merely adds capacity.

The operator also names no booking platform or trade-partner terms, leaving sellers without terms that could shift distribution economics. Long sales dates extend the commercial horizon, but they do not constitute evidence of bookings.

How does the propulsion claim work?

Magellan Discoverer combines an ABB Onboard DC Grid power system, two ABB Azipod units and a Corvus Energy battery storage system. On battery power, Antarctica21 says the ship can operate in near silence with zero emissions.

The company plans to use that mode during low-speed transits, approaches to landing sites and manoeuvres near wildlife; this is an operating intention, not published test data. Two MAN main engines use Selective Catalytic Reduction, an emissions-control system, and meet the International Maritime Organization’s (IMO) Tier III standard, while a heat-recovery system warms interiors and onboard water.

The zero-emission claim applies only to battery operation. The announcement publishes no battery size, operating range or full-vessel emissions test, preventing an independent comparison with conventional expedition ships.

Antarctica21 is also CarbonNeutral certified, a company-level designation whose scope the announcement does not specify. The operator belongs to the International Association of Antarctica Tour Operators (IAATO).

Who built the vessel, and what remains unproven?

ASENAV designed and built Magellan Discoverer in Chile and also delivered Antarctica21’s Magellan Explorer in 2019, giving the operator a repeat-builder relationship. The announcement does not compare the two vessels on capacity, fuel consumption or operating costs, so sellers cannot derive a unit-economics advantage from the shipbuilding link.

Chief executive Verónica Peragallo called the ship the company’s “most refined air-cruise offering, and our most responsible.” She said: “Antarctica21 was founded on the belief that there had to be a better way to reach and explore Antarctica, and that spirit still drives everything we build.”

Peragallo added that the vessel carries small groups and a team that knows every guest, and produces “the quietest, cleanest propulsion we have ever put to sea.” She thanked the hundreds of people at ASENAV, Antarctica21 and partner companies who worked on the build.

Antarctica21 says it pioneered the Antarctic air-cruise format—flying guests over the Drake Passage before they board expedition vessels—in 2003. That history supports the company’s brand positioning, but the announcement supplies no operator-wide market share, guest spending or profitability figures.

Actual occupancy rates, prices and operating data from the December 15 sailing and the 2026–27 two-ship deployment will show whether the 88-guest vessel expands revenue and market share rather than simply adding inventory.
