Ocean Explorer, the newest addition to the fleet, is modern, elegant and purpose-built for polar exploration. The 138-passenger vessel has been designed with the latest in expedition ship technology. One of the ship’s key features is the ULSTEIN X-BOW®, a marine engineering innovation that ensures a comfortable and smooth sailing experience thanks to the inverted bow. Located at the bow is the two-story, light-filled library, which introduces a welcome airiness to the expedition ship.
