M/V Janssonius is one of the newest vessels in Antarctica.  The ship exceeds all green requirements of the Polar Code. Janssonius has a maximum capacity of 170 passengers (80 cabins), and a crew and staff of 72.

Janssonius is 353 feet long and has a beam of 58 feet. This Antarctic cruise ship has an ice rating of Polar Class 6 (equivalent to 1A-Super), the highest Polar Class notation for ice-strengthened vessels. Janssonius is ideally suited for Antarctic exploration.

Janssonius is a swift Antarctic cruise vessel, with an average cruising speed of 15 knots. That’s up to 5 knots faster than many other polar expedition ships–a real advantage when crossing the Drake Passage.


Onboard amenities include a library, bar, lecture/observation room, dining room, spacious observation lounge, and infirmary.

All meals onboard the ship, including snacks, coffee, and tea are included in all itineraries. Janssonius has a non-smoking policy, but guests can smoke in certain designated outside deck areas. Laundry service, bar, beverages, telecommunication, and excess baggage all carry an additional cost.


Janssonius philosophy is to keep open-sea crossings short, allowing the voyages to maximize onshore and near-shore activities. Janssonius carries a fleet of rigid-hull inflatable Zodiac boats — enough for all passengers to be off the ship at the same time. The vessel has two separate gangways and a sheltered indoor Zodiac embarkation platform that can also be used for special outdoor activities, such as kayaking. Zodiac cruising and onshore hiking are included with every departure (weather permitting).

Special interest activities such as kayaking, hiking, snowshoeing, mountaineering, and polar diving are available on selected voyages. Our team of LANDED travel specialists can help you select the voyage that’s right for you.

When you aren’t exploring the Antarctic on land or cruising the coastline in a Zodiac, you can enjoy the Janssonius program of lectures, delivered by the expedition team’s naturalists and adventure guides.
