Plans for the world’s largest luxury yacht hotel, which was due to open in London in time for the 2012 Olympics, have been put on hold as a result of the global economic crisis.

According to the original plans, the 170 metre super-yacht would have been permanently moored at London’s Docklands, with 158 rooms and suites.

Remember the solar powered Dubai Sea Limousine (an eco-friendly mode of transportation to and from the islands of The World)?

Raising the bar further, Dennis Ingemansson has designed the Solar Gem superyacht that shows the trend toward the eco-friendly yachts of the future.

Not only is it made of recyclable material, but it also has a hybrid electric system which is fueled by solar and wind energy.

Russian oligarch, Roman Abramovich’s mega-yacht ‘Eclipse’ has finally made a preliminary launch at the Blohm & Voss shipyard in Hamburg, Germany where it was built secretly for more than two years.

Estimated to have cost around $500 million, the vessel is nearly 170 meters long.

It has room for 24 guests, with a crew of 70. It is 13,000 tonnes, and can achieve a top speed of 33 knots. Its cruising speed is 22 knots.

The Infintas yacht is the second design launch of Schöpfer Yachts and is just as impressive as its first one, the Oculus Superyacht.

The new 300-foot (91.5 meter) Infintas superyacht has been designed by E. Kevin Schopfer with Sparkman Stephens, Naval Architects.

While the Oculus was inspired by an oceanic fish, the Infintas draws inspiration from the infinity symbol, which is highlighted within the yacht’s elevation.

This amazing look machine is the Code X Yacht, an ultra performance hybrid sports boat built by Code-X in Meggen on Lake Lucerne in Switzerland.

She’s powered by a pair of Ilmor Marine 710 horsepower V10 Formula 1 engines that push along at 90 knots (167 km/h).

For less frenetic, more environmentally conscious cruising, the owner can choose, via a touch-pad screen, to rely either solely or partly on a bank of photovoltaic modules supplying electric motors and/or lithium batteries.

Alastair Callender took luxury yachting to all new highs with his recent project, the “Soliloquy,” which is not only a luxury yacht, but also an eco-friendly one.

It is run by wind, solar and Hybrid Marine Power technology.

“The use of renewable and hybrid-electric energy will bring zero-emission capabilities and result in greater savings in fuel costs”.
