Antarctica21 has welcomed Magellan Discoverer, its first purpose-built hybrid-electric expedition ship. The vessel was christened in Punta Arenas, Chile, on November 6, 2026, ahead of its first passenger voyage on December 15.
Built by Chilean shipyard ASENAV in Valdivia, the ship accommodates up to 88 passengers in 40 cabins, all with private balconies. Onboard features include a 360-degree observation and walking deck, an accessible bow, a panoramic sauna, and a dining room that can seat every guest at once.
With a Polar Class 6 rating, Magellan Discoverer will operate alongside its sister ship, Magellan Explorer, during the 2026–2027 Antarctic season.
The vessel will mainly serve Antarctica21’s fly-cruise programme. Passengers fly for about two hours between Punta Arenas and King George Island, then continue on expedition voyages in Antarctica. This replaces the roughly two-day sea crossing through the Drake Passage in each direction, shortening travel time and avoiding potentially rough conditions.
For its inaugural voyage, however, the ship will sail south from Punta Arenas through the Strait of Magellan and across the Drake Passage. Passengers will return by air from King George Island.
Its hybrid diesel-electric propulsion system includes battery storage, allowing the ship to operate on battery power for limited periods with less noise. This capability is intended for low-speed travel, approaches to landing sites, and manoeuvres in areas where wildlife may be encountered. Antarctica21 says the ship adds quieter propulsion technology to its small-group air-cruise programme.
