Sophisticated yet robust, with greater space and interior volume than other comparable sized explorers, the Doggersbank 66’ Offshore by Altena is ideally positioned for solo sailors or adventurous couples looking to strike out on their next seagoing voyage. Easy to self-pilot and boasting ample deck space, including room for a max. 16′ / 5.00m tender and al-fresco dining, the boat has an ergonomically designed interior capable of accommodating six guests in three elegant lower deck cabins, including two full-beam doubles.
This beauty of an explorer yacht already comes packed with a tender and motorcycle, and is in exquisite condition.
