Massive 480ft superyacht worth £30million can purposely SINK itself – but it does so for a very good reason

THIS gargantuan superyacht worth an eye-watering £30 million sinks at the push of a button - but for an unbelievable reason.

Unbelievable images show the industrial-ship-turned-megayacht submerge itself to hold various vehicles from land or sea on its aft.

The vessel - bizarrely named OK - is built to host a whopping 20 guests who can drive, fly, or sail onboard due to the vessel's ability to partially sink.

OK began its life back in Japan in 1982 as a yacht transportation ship - which, with its makeover, is still capable of doing.

In 2019 the works began to transform the industrial vessel into a £30 million work of art - and finished in 2022.

The 480ft semi-submersible is designed with open deck space that has endless storage for any vehicles its wealthy owner would want to put on it.

This could include up to a whopping 151ft sailing yacht and even a sea plane.

Maritime vessels are able to sail right onto the board with no problem thanks to the yacht's unbelievable ability to submerge its aft platform which sits in the middle.

It works by the ship taking on water ballast to allow the load to be floated over the deck.

Once it's in position, the water ballast is dumped from the vessel and the deck and cargo return to sitting above the water line - as if nothing happened.

If guests were to have smaller toys and tenders, it's no problem, as that's what the 40-tonne crane is for as it launches and recovers the vessels.

A luxurious car ramp allows road vehicles onto the deck - making the ship completely adaptable from land to sea.

OK also sports an ultra-luxurious indoor swimming pool that's surrounded with glass windows, allowing visitors to get perhaps a fake sea swim experience.

An outdoor cinema is also set up along with a botanical garden and a whopping four aquariums.

And in a bizarre addition, once the aft deck is cleared, the space can be used as an open-air tennis court.

Accommodation for guests and crew sits in the forward area of the luxury ship's structure and can sleep 20 guest onboard.

The unusual vessel was originally a transportation ship dubbed Super Servant 3, built by Japanese commercial shipbuilder Oshima Shipbuilding.

But, after being redesigned by exterior designer and 2015's Young Designer of the Year winner Timur Bozca, OK was born.

Discussing his creation, Bozca said: "The vision was to create a floating island concept that could hold many toys - even a seaplane or another superyacht - without breaking the powerful outlines of the previous version."

In recent years OK has resided at Karmarine Shipyard in Turkey, but it is unclear where the incredible vessel is now.

Similarly an ultra-luxury megayacht designed like a military-style aircraft carrier promises to be a sheikh's paradise at sea.

Plans for the "Floating Dubai" vessel include an enormous pool deck, a relaxing spa and not one, but two enormous helipads on board.

Christened UAE One, the superboat was designed by Milan-based Enzo Manca, who collaborated with a sheikh to make it the flagship of the United Arab Emirates.
