The Greg Mortimer Antarctic ship by Aurora Expeditions is designed to make the experience at sea easier for people who usually get queasy. But if a new ship called the "X-Bow" delivers on its promises, that could be a problem of the past. The first X-Bow ship to make its appearance on the consumer market is the Greg Mortimer by Aurora Expeditions, which specializes in cruises to Antarctica. "What we've lost is that big Leonardo DiCaprio moment at the front of the ship," Primrose says to CNN Travel, referring to its unique design. "But then when the ship is stationary we have hydraulic platforms that pock out from the sides and go flat."
