The 55 metre superyacht Quinta Essentia, the largest vessel ever launched by the Netherlands’ Heesen Yachts, has been listed for sale for $100 million.

With sleek exterior lines by Frank Laupman of Omega Architects, the yacht’s most striking feature is a grand swimming pool on the aft deck complete with a waterfall.

The yacht has a very modern interior by Ken Freivokh Design and Michela Reverberi with metallic silver accents.

More renowned for its prowess with wheeled vehicles, Toyota Motor Corp. is increasing its seaborne fleet with the launch of a new leisure boat, the Ponam-35.

But the 11.95-meter cruiser is still related to the car manufacturer’s mainstream products as its two V8-cylinder engines are adapted versions of the 4.5-liter V8 diesel engine that can be found in the Toyota Land Cruiser.

And while elsewhere it might be considered unusual for a car firm to dabble in pleasure boats, several of Japan’s other major auto firms also have boat divisions.

Pearl Motor Yachts, one of the UK’s leading luxury yacht builders, has announced a special collaboration with British interior designer Kelly Hoppen MBE.

Kellyis has been brought on board to design the luxury interior of the flagship Pearl 75, which will be launched in early 2012.

Kelly creates stunning interior designs for luxury homes, yachts and private jets for an ever-expanding international high-profile client base.

A Saudi sheikh left Roman Abramovich stranded at sea this week after taking the last megayacht berth at the so-called “Millionaire’s Quay” in Cap d’Antibes.

The Russian oligarch had wanted to moor his massive $800 million, 533-ft. yacht Eclipse, at the famed dock but arrived to find the only available spot had just been snatched by Saudi Arabian royal Prince Aziz al Saud.

According to Dailymail, the last space in Europe’s biggest yachting harbour simply wasn’t big enough for the two superyachts.

This superyacht - dubbed the ‘Tropical island Paradise’ – has been designed by British boat builders Yacht Island Design.

The 90m Tropical Island Paradise design has a theme that is centred around a secluded island paradise, with elements inspired by the islands of the Caribbean.

The main exterior deck is a private beach “cove” with a voluminous ocean view swimming pool located forward that is fed by a stream emanating from a cascading waterfall on the volcano further aft.

Six months after he finally took delivery of the Eclipse, the world’s largest yacht, Roman Abramovich is offering it up for charter at a rate of $2 million per week.

The 538-ft. Blohm + Voss behemoth is available via ultra-exclusive brokerage SuperYachtsMonaco, and is the world’s most expensive yacht charter by far.

The yacht, which has space for 30 guests and 75 crew, reportedly features a military-grade missile defense system, armor plating, bulletproof windows, three helipads, two swimming pools and a wellness center, among other luxe amenities.
