Douglas Mawson features the X-Bow by Ulstein Design & Solutions, and is equipped with Safe Return to Port, virtual anchoring and zero speed stabilizers. The vessel provides a wide range of amenities, including a swimming pool, bar and restaurants, lounges, a boutique, gym, spa, and sauna, all while maintaining an exclusive atmosphere for the guests.
The vessel represents an international collaboration between Norwegian naval architects (Ulstein), Swedish-American interior designers (Tomas Tillberg Design USA), Finnish interior contractors (Makinen), and a Chinese Shipyard (CMHI).
