Featured solutions

The flexible design of the INFINITY class series opens up new possibilities for every new vessel. The 'Ocean Explorer' is vessel number four and is operated by Vantage Cruise Line. The 'Ocean Explorer' stands out from vessel number 1, the 'Greg Mortimer' by having an infinity pool installed on deck 7. Like her sister vessels in this series, she is carrying the patented Ulstein feature, the ULSTEIN X-BOW®.

A new feature on this vessel is an atrium forward consisting of a two-level lounge with a piano bar and panoramic bow windows.

When the vessel visited Oslo in July 2022, some of our ship designers paid a visit on board for the first time since the vessel's completion at the CMHI yard. They received feedback from the crew, who are stunned by the vessel's soft motions in the sea, comparing her movements to a dolphin. The bow lounge with the windows is impressive and adds an extra wow factor - and a lot of light - to the vessel, and the lounge is very popular among the guests.

The bow lounge with windows, the photo was taken by the Ulstein designers in July 2022.
