Sleek, space age, and sparkling. If these naval architects have their way, the superyacht of the future will resemble more of a floating piece of art, than a traditional boat.



From glass cubes inspired by Lego, to spiraling decks modeled on opera houses, these are some of the dream designs of industry insiders.



But will their fantastical vessels actually see the light of day? With estimated price tags in the hundreds of millions of dollars, it will take an adventurous client -- and one with deep pockets at that. Courtesy Lujac Desautel

"Paying homage to the skyscraper and acting as a canvas to the sea, GLASS is organized vertically in three cubic floors stacked upon each other like Lego blocks," he explained.



"Not only is glass a beautiful material which allows for an abundance of natural light and uninterrupted views -- it's also an extremely strong material which can be manufactured to be as tough as concrete."

The 22-year-old designer knows a thing or two about luxury yachts -- he crewed on them in the Mediterranean during his summer holidays at architecture school.



"It seemed crazy to me that someone would spend tens, if not hundreds of millions of dollars, on a boat that had little to no windows. It felt unnatural to be cruising on the most beautiful waters in the world, and have little notion of the outside environment," he explained.



"I asked myself, if the tallest buildings in the world are built out of glass then why can't a boat? Ultimately, GLASS was a natural manifestation of these simple questions." Courtesy Lujac Desautel

It seems fitting that the first sketch of this space-age superyacht was penned on a napkin. In many ways that's exactly what it looks like, against the endless expanse of ocean.



"Most yacht clients, whilst they like to have a unique design, tend to be pretty conservative and don't want to be too different from the majority," explained



"For this reason, superyacht design is incremental and design evolves at a very modest pace." It seems fitting that the first sketch of this space-age superyacht was penned on a napkin.

"There is no doubt that an owner who would commission STAR would be one who wanted to 'break the mould,'" said Russian designer Lobanov.



At 132 meters long, and 60 meters high, the STAR would have a price tag "somewhere in the region of €450 million ($562 million)," said Lobanov. Courtesy Igor Lobanov

This superyacht would accommodate 36 overnight guests and feature a helicopter landing pad.



"Each superyacht owner is different -- some like to be very involved in the creative process and help sculpt their dream boat in every detail. While others give a loose brief and leave the designer to it," explained Lobanov.



"Ultimately, owners tend to be money-rich and time-poor, so the final vessel should provide a haven for them to escape." Courtesy Igor Lobanov

"The idea was that the frames could be like veins," explained Hadid. "I like this kind of project because every time you do them, you learn about some other type of parameters which you had not always considered.

X R-EVOLUTION, designed by Stefano Pastrovich



At first glance, it might look as though there are five vessels in this picture. In fact, it is just one. The 77 meter superyacht X R-Evolution features detachable floating decks which can be deployed away from the main boat.

"I wanted to have a boat that was able to access the islands from very close -- which isn't always possible in superyachts of this size."

If a superyacht isn't big enough to really "get away from it all," guests could always float away on their own deployable deck.



"I do very extreme designs, because that's me, that's my personality," says Pastrovich.



"My customers are very genuine, brave, challenging people. They don't want another white piece floating on the water. They want something incredible that does not exist." Courtesy Pastrovich

Pastrovich is also behind the 92 meter Beach Club concept, resembling something between a fishing trawler and a private island.



"For a long time I've tried selling the idea to my clients of putting sand on a vessel -- people thought I was insane," he says with a light laugh.



"But I like the idea that the cabin is in a beach house style, and that when you wake up in the morning there is a little umbrella outside your room and you feel like you're at the beach." Courtesy Pastrovich

With designs like this, it will take an ambitious client to make Pastrovich's dream boat a reality -- a hard task in what he describes as a "very conservative yachting industry."



"I think there is a new market emerging from Asia and the Middle East, and they are the ones who invite you to do some crazy, unknown things," he explained.



"I think the Asian market in particular will go for something unconventional because they don't know what is conventional. China, for instance, is not a country that is used to going to the beach like Europeans. So they're discovering the world of the sea.



"They can say 'let's go outside the box,' because they don't have a box to begin with." Courtesy Pastrovich
