Featured solutions

The flexible design of the INFINITY class series opens up to new possibilities for every new vessel. The 'Ocean Explorer' is vessel number four, and will be 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. Furthermore, and novel for this vessel, is a unique entrance atrium on deck 4 and 5 in way of main passenger entrance port and starboard. Another feature is an atrium forward consisting of a two-level lounge with piano bar and panoramic bow windows.

Like her sister vessels in this series, she is carrying the patented Ulstein feature, the ULSTEIN X-BOW®.
