Can ship design cure seasickness?

In October 2019, the first ULSTEIN X-BOW® polar expedition cruise vessel, 'Greg Mortimer', left Ushuaia for her inaugural voyage. She was heading for the dreaded Drake Passage to reach Antarctica.

The X-BOW® makes a huge difference in sea behaviour. It splits the wave energy and reduces the slamming impact. Successfully proven in more than 100 ships, the hull shape has recently become a game changer for expedition cruising. Yachts will be next.
