Originally built as an oceanographic research vessel for the United States agency NOAA (National Oceanic and Atmospheric Administration), the M/S Ushuaia has been refurbished to accommodate a maximum of 84 passengers in 41 comfortable twin cabins and suites.

The ice-strengthened polar vessel is very well appointed and provides ample deck space and an open bridge policy. During the days the ship is underway, guests are invited to observe the navigational operations of the ship and officers will gladly answer questions. A full complement of inflatable landing craft ensures superb landings and wildlife viewing opportunities on the otherwise inaccessible coastline.

All cabins include en suite facilities, individual temperature controls and ample storage space. Public areas feature a large dining room (one open sitting), an observation lounge and bar, a conference room with modern multimedia equipment, a well-stocked library, a changing room and a small infirmary. A gift shop is stocked with apparel, film, sundries, gift and souvenir items.

The Ushuaia is equipped with the INMARSAT system, which allows direct communication with the ship by telephone and fax from any location in the world. Emails can be sent and received at a per-minute charge. The ship's bridge has a computer for passengers' use, and emails will be sent several times a day. There is no Internet access.

Electric current on board is 110 V/ 60 Hz and cabins are fitted with multi-type sockets suitable for several international plugs. However, guests are advised to bring necessary converters and any special adapters, as only a limited number can be borrowed on board. Some outlets in public areas are 220v-240v and are clearly marked, though they are fitted with Argentine outlets.

The Ushuaia's expert captain, officers and crew are highly experienced in Antarctic navigation and have a great love of nature. An onboard specialist team of international expedition leaders and lecturers enhances the voyage, and all are extremely knowledgeable, enthusiastic, helpful and dedicated to the protection of the environment. The ships's chefs prepare excellent cuisine including regional specialties, and the bar is well-stocked with carefully selected wines and spirits. Most special dietary requests can be readily accommodated with at least three weeks' advance notice.
