A high-end luxury yacht with its own volcano
As luxury yachts go this will be up there with the best.
According to website Australian.au this one comes complete with a volcano, cascading waterfall and floating tropical islands.
The futuristic luxury yacht
The lavish 90m vessel - designed by British boat builders Yacht Island Design - is fittingly called Tropical Island Paradise and can accommodate up to 10 guests.
The designers have let their imaginations run wild, with a waterfall flowing down through the volcano into a huge swimming pool which is surrounded by secluded cabanas and palm trees.
Inside the volcano is an owner's suite spread over two floors, a cinema, gym, library and private spa.
There is also a helicopter landing pad, large bar and, for extra seclusion, small floating islands at the back of the boat which come complete with deckchairs and pergolas.
The designers say the fanciful yacht - which does not have a price tag and is still at the concept stage - challenges the norms within the yachting industry with "bold and daring ideas".
The company has also designed a luxury yacht based on the streets of Monaco and its Grand Prix circuit, which features a fully functional go-kart track, a huge swimming pool and luxury apartments.
It also creates bespoke vessels for discerning millionaires.
