Not all yachts are meant to spend their lives floating in sunny, calm waters. The Damen Expedition Yachts are meant for exploration and have the IMO Arctic and Antarctic certifications to prove it. The 227 feet version houses a fully-equipped dive center with tri-mix facilities for deep diving, a U-Boat C-Researcher submarine, and a Saab Falcon remote vehicle. On the deck is a fully-certified helipad with a hangar for the custom Airbus H130 helicopter, as well as space for multiple tenders. Despite its rugged feature list, the interior is far from utilitarian, so as to provide greater comfort on long voyages.
