Antarctica21 has officially welcomed Magellan Discoverer, its first purpose-built hybrid-electric expedition vessel, to its fleet. The ship was christened in Punta Arenas, Chile, on November 6th, ahead of its maiden passenger voyage scheduled for December 15th, 2026.
Built by Chilean shipyard ASENAV in Valdivia, Magellan Discoverer accommodates up to 88 passengers in 40 cabins, each featuring a private balcony. Onboard facilities include a 360-degree observation and walking deck, an accessible bow, a panoramic sauna and a dining room designed to seat all guests simultaneously. The vessel meets Polar Class 6 ice-class standards and will operate alongside its sister ship, Magellan Explorer, during the 2026–2027 Antarctic season.
The ship will serve Antarctica21’s air-cruise programme, which combines flights between Punta Arenas and King George Island with expedition voyages in Antarctica. The ~2-hour flight replaces the conventional sea crossing through the Drake Passage, which typically takes around two days in each direction, reducing transit time and avoiding potentially rough sailing conditions.
For its inaugural voyage on December 15th, however, Magellan Discoverer will operate a different itinerary, sailing south from Punta Arenas through the Strait of Magellan and across the Drake Passage before passengers return by air from King George Island.
Its hybrid diesel-electric propulsion system incorporates battery storage, enabling limited periods of battery-powered operation with reduced noise. The capability is intended for low-speed transits, approaches to landing sites and manoeuvres in areas where wildlife encounters are likely. According to Antarctica21, the vessel represents the company's latest development in its air-cruise offering, combining small-group expedition travel with quieter propulsion technology.
