We introduced you to the 115-metre Migaloo submarine concept in 2013, and now the designers at Migaloo Private Submersible Yachts have come up with the perfect place to keep it alongside: the semi-submersible Kokomo Ailand. With an LOA of 117 metres and a beam of 78 metres, you won’t be stuck for space. Initial renderings show a garden deck with alfresco dining, and a jungle deck with waterfall, palm trees and a botanical garden.

The semi-submersible ‘yacht’ has a draught between 9.7 metres and 20.5 metres

The owners benefit from a penthouse deck, a staggering 80 metres above the water, incorporating two elevators and a glass-bottomed hot-tub. A helideck is available for quick transfers and there is a planned spa deck.
