Launched in 2019, the Greg Mortimer is a cutting-edge expedition vessel purpose-built to explore the polar regions—and it brings that same spirit of adventure to Alaska’s glacial waters. The ship's signature inverted X-Bow™ delivers exceptional stability in dynamic seas, while its intimate 154-guest capacity fosters a personal onboard experience. From hydraulic viewing platforms that extend over the water for extraordinary wildlife encounters, to rapid-deploy Zodiac platforms that offer swift access to nature—every detail is designed to deepen your connection to Alaska's untamed landscapes.
