The largest and most extravagant of the WIDER Superyacht range, the STERN represents the finest in style, design, practicality and ingenuity.
Originally developed to fulfill an owner's desire to equip his vessel with a submersible for thrilling underwater adventures, the STERN is a no-compromise vessel that features advanced multi-functional systems, user-friendly technology, diesel-electric propulsion, and an enhanced relationship with the sea via the STERN beach club area, side platforms, balcony, and an interior seawater swimming pool.
Constructed entirely in aluminium, the elegant silhouette of the WIDER 165 was created by Fulvio De Simoni in collaboration with Tilli Antonelli and the in-house WIDER design team. The STERN has been designed to enhance the owner's contact with the sea, while significantly increasing interior volumes compared to other 165' motor yachts.
The STERN Beach Club has some of the most generous measurements of any other in the market in comparison with similar length yachts. As a result, you can enjoy moments of pure relaxation in close contact with the sea. There are two platforms on either side that drop down at water level. The hangar, with an indoor salt water pool, can host a tender such as the WIDER 32, and a submarine or, alternatively, a spa.
The STERN is equipped with a serial hybrid propulsion system and azimuthal thrusters, a system with four generators controlled by a smart power management system in conjunction with the very latest cutting-edge battery technology. The power produced runs the yacht and all the hotel functions bringing about many advantages, from greatly reduced consumption to highly increasing the cruising range.
The traditional engine room has been replaced by a more flexible structure allowing the use of the central part of the hull for accommodation, so more spacious guest cabins can be designed at the heart, and the most stable zone, of the yacht. A Power Generator Room is in the bow and a Technical Room in the stern where the lithium polymer (LiPo) batteries are housed. Only possible because the power is transferred to the azimuthal thrusters via flexible wiring replacing the rigid drive shafts.
All the on-board power sources are controlled by the Power Management System (PMS) developed by WIDER with Nidec Industrial Solutions, a market leader in the field of energy technologies. The system is fully integrated with the superyacht and handles the power coming from shore, the generators and the battery packs, and distributes it to the hotel functions, the propulsion system and the battery recharge system as required.
The entire propulsion system is completely modular: the STERN can be run exclusively by the batteries in Zero Emission Mode (ZEM) or by activating up to four in-line diesel generators. This allows the greatest navigation range to be achieved while limiting fuel consumption.
Wide floor-to-ceiling windows envelop the lounges of the main deck, allowing natural light to pleasantly illuminate the spacious living areas and allow magnificent views of the yacht’s surroundings.
One of the most exceptional features on board can be found in the area reserved for the owner: an apartment that extends across the complete beam of the yacht with two private balconies overlooking the sea.
On the main deck, as well as a spacious lounge again with full height windows making it extremely bright, there is a gym and a sauna. On the upper deck, there is the Sky Lounge and a dining area with sliding doors, which once retracted create the feeling of an open but sheltered alfresco dining area.
On the lower deck there are four spacious guest cabins all with bathrooms; two of them double VIP cabins and two twin cabins.
A large cabin on the upper deck adjacent to the wheelhouse is reserved for the captain. Crew members have four twin cabins in the lower deck, along with the wide crew mess. These cabins are on either side of a central corridor with direct access to the engine room in the bow and away from guest cabins. Accommodation meets the latest LY3 standards.
The beach club of the STERN is an ideal hangar for a designer tender like the WIDER 32, due to the ease with which the floating launching system makes exit and entry manoeuvres with the tender possible. The submarine will also be stowed here and likewise the launch and retrieval is simple for the crew.
On the upper deck towards the bow there is a helipad that can easily be transformed into a dance floor.
The maximum speed of the STERN is 14 knots. At a cruising speed of 13 knots, the yacht is estimated to have a range of 3,100 nautical miles that rises to 5,400 at an eco-speed of 10 knots.
The yacht has the ability to run just on its battery power in Zero Emission Mode with silent cruising at a reduced speed of 5 knots. This is the ideal selection for short trips or in order to cast off early in the morning ensuring the utmost quiet with no generators needing to be started.
