Antarctica21 has announced the launch of Magellan Discoverer, the first hybrid-electric expedition cruise ship built in the Americas. The vessel is set to enter service for the 2026–27 Antarctic season, with bookings now open through early 2028.
Built in Chile and designed specifically for Antarctica21’s air-cruise expeditions, Magellan Discoverer marks the next phase in the company’s small-ship fleet evolution. Measuring 94 metres in length, the ship will accommodate 76 guests across three passenger decks, supported by 67 crew members, maintaining the high crew-to-guest ratio that characterises the Antarctica21 experience.
The vessel features a hybrid-electric propulsion system that combines marine batteries with International Maritime Organisation (IMO) Tier III-compliant engines, helping reduce carbon dioxide emissions and underwater noise while improving overall energy efficiency. The ship also incorporates systems that recycle engine heat for onboard heating and recover operational energy, supporting lower-impact expedition cruising in Antarctica’s fragile ecosystem. Built to Polar Class 6 specifications, Magellan Discoverer is designed for safe and responsible navigation in polar waters.
The ship offers 40 cabins, including Grand Veranda Suites, Family Suites, Deluxe Veranda Cabins and Single Veranda Cabins. Each cabin features a private balcony, appealing to travellers seeking privacy and comfort while exploring remote destinations. Public spaces include an observation lounge, gym, sauna and dining areas designed by Tomas Tillberg Design, reflecting a contemporary aesthetic inspired by Patagonia and Antarctica.
Magellan Discoverer will join the company’s existing vessel, Magellan Explorer, expanding Antarctica21’s capacity for its signature air-cruise expeditions. Travellers fly directly from Punta Arenas in Chile to King George Island, bypassing the Drake Passage and allowing more time exploring Antarctica — a format increasingly popular among travellers seeking efficient and comfortable polar journeys.
Commenting on the launch, Juan Cristóbal Del Pedregal Bravo, Senior Commercial Director of Antarctica21, said the new vessel reflects the company’s continued commitment to responsible, small-scale Antarctic travel. He noted that the hybrid-electric technology supports environmental goals while the boutique ship size ensures the flexibility and personalised experiences expected by expedition travellers.
Antarctica21 remains CarbonNeutral® certified and continues to invest in sustainability initiatives, including renewable energy integration at its Explorers House facility in Punta Arenas and testing synthetic e-Fuels for Zodiac operations. The introduction of Magellan Discoverer further reinforces the company’s commitment to combining technological innovation with low-impact exploration in Antarctica.
