A jaw-dropping 480-foot superyacht that can be submerged in water and boasts an open-air tennis court has set sail after a three-year conversion.
The unique vessel, named OK, began its life as a yacht transportation ship in Japan in 1982 before work began to transform it into a semi-submersive yacht at the Karmarine Shipyard in Turkey.
Exterior designer Timur Bozca, who won the Young Designer of the Year award in 2015, said OK has the ability to submerge almost 70 percent of itself.
The vessel – described as an undiscovered island – has room to carry a 46m sailing yacht and a sea plane and is estimated to be worth $40 million.
It also features a tennis court, outdoor cinema and room for 20 guests.
It was originally built in 1982 as a semi-submersible yacht transportation ship – but has been transformed into an expedition vessel.
It is currently based at Karmarine Shipyard in Turkey.
The vessel’s submerging capacity enables it to sink the middle platform of the boat in order to allow cargo to be carried just above water.
The feature also means that once the deck is cleared guests can use the open-air tennis court on the water.
Designed with enhanced internal strength, the vessel, which has enough room to carry a 150-foot sailing yacht and a sea plane, can handle both stern and side loading.
