Poseidon Expeditions - your polar cruise operator

About us / Our ships

Small Ships — Big Advantages

Our fleet goes where other ships cannot follow. Our small expedition ship Sea Spirit can navigate into protected channels and bays that are out of bounds to larger cruise ships. Importantly, her smaller passenger numbers mean that everyone can go ashore simultaneously at landing sites in Antarctica and the Arctic where regulations limit the number of visitors ashore. Our icebreaker 50 Years of Victory is perfectly suited to cruising across the frozen Arctic Ocean. She is the only vessel currently capable of fulfilling your dream of reaching the North Pole!

The balance between luxury and expedition is another important factor that we have carefully considered. We pride ourselves on offering the perfect combination of both. Our ships provide a high level of comfort and amenities, while our crew and staff deliver the extraordinary service expected by discerning cruise-travelers. At the same time, we offer exciting excursions and adventure options to satisfy your inner thrill-seeker. All of this is available on itineraries that take you deep into the most remote areas of the planet, fulfilling your desire for real expedition.

This careful balance is reflected in the elegant and easygoing atmosphere on board. On our ships you can enjoy an authentic and exciting adventure as well as relaxation with friends, all in exceptional comfort and style.

Nuclear icebreaker


The i/b 50 Years of Victory is the largest and most modern nuclear-powered icebreaker in the world. The spoon-shaped bow of the ship is designed for greater icebreaking ability and makes the ship capable to force its way through 2.5 meters thick ice fields.
