Heesen Yachts announces delivery of fully custom 51m motor yacht MySky (YN 16551)

January 12, 2015

Heesen Yachts is thrilled to announce that YN 16551 motor yacht MySky was handed over to her owners on November 28, 2014, following intensive sea trials in the North Sea.

The bold but sleek exterior of luxury yacht MySky comes from the pen of Frank Laupman of Omega Architects: Flush-mounted tinted windows thermo-bonded to the superstructure create a continuous wall of glass that gives this vessel a highly distinctive look.

The owners of MySky yacht appointed world-renowned architect Erick van Egeraat to design the ultra-contemporary, sharp and sophisticated interior. A combination of crisp white leather with dark high-gloss Makassar wood and spectacularly patterned backlit white onyx inlaid within a black marble base contribute to the strongly contrasting monochrome theme. This motif is used throughout the interior producing a highly stylised, luxurious ambience.

MySky superyacht accommodates up to 12 guests in five luxurious cabins. The spacious full-beam master suite is traditionally located on the main deck forward and boasts a large, elaborate bathroom including a natural stone clad steam shower and a spacious walk-in closet. The remaining four guest cabins are located on the lower deck and furnished to the highest specifications.

Guests will enjoy life at sea both inside and on-deck: The main saloon aft, with its large circular dining table, lounge and bar area with a 6 square metres LED screen connects to the main deck aft, which features built-in settees and seats around two low coffee tables for optimum relaxation. The upper deck lounge, with its 270-degree view and stunning rotating, circular, white leather seating area, opens onto the aft terrace, accommodating a large dining table ideal for entertainment and al fresco dining under the stars, even under way. Above, the Sundeck’s large Jacuzzi, surrounded by sun-pads, is perfect for recreation, rest and repose.

A fully equipped gymnasium is located on the sundeck and is key to the design that has been created to satisfy the owner’s requirement for quality time for sports, physical training programmes and being in the outdoors.

Finally, the touch-and-go helicopter pad forward of the bridge can transform into another large sun terrace providing secluded lounging even when the yacht is docked stern-to.

Mark Cavendish, Sales and Marketing Director of Heesen Yachts, comments: “MySky is a very important achievement for our shipyard. Working with Erick van Egeraat and his team – who are new to yachting but are a very talented team of architects – pushed Heesen to overcome its boundaries. I believe that MySky will turn heads!”

Younique Yachts’ Tender to 73m motor yacht YALLA shortlisted for Tender Design Award 2015

December 29, 2014

Built for Italian shipyard CRN earlier this year, a limousine tender to the 73-metre motor yacht Yalla (CRN 132) has been shortlisted for the Tender Design Award 2015. Younique Yachts has constructed T/T mega yacht Yalla in close partnership with two other Dutch companies: Frank Laupman of Omega Architects and Van Oossanen Naval Architects.

The unique design by Frank Laupman was built according to the highest quality standard. T/T superyacht Yalla is 31 ft long and with a water displacement of 4500 kg it reached a top speed over 40 knots during the trial run. During the mandatory sea trials on the North Sea the tender performed exceptionally well despite the choppy water.

People can board the ship on the lower aft deck or the higher foredeck, enabling the crew to help passengers get on and off board safely. A smartly designed bow ladder is available for easy access to the beach. Comfortable leather seating offers ample room to sit for 12 persons. To keep the temperature at a pleasant level, a double climate control system has been installed. The crew in the cockpit has a good view of the accommodation and can swiftly and easily reach the engine and installations.

Frank Laupman listened to the owner’s wishes and designed a tender that is just good-looking and representative as the mother yacht. The lay-out of its teak decks, the unique colouring of the window glass, the paint job, the leather and the finishing… Everything was designed and executed with the mother yacht in mind. The windows of the Tender to super yacht Yalla are real eye-catchers. The specialists of Younique Yachts custom built the 12 separate windows to form a sleek and smooth whole.

Unity and uniformity is what Younique Yachts is all about. Windows, door fittings, fender hooks and all other separate parts need to form a balanced unity.

New range of tenders

Younique Yachts is currently working on the design of a new range of 9.5m tenders. “The new range will be based on three different models,” says Egbert Wattel of Younique Yachts, “a Supply Tender for crews, a Sports Tender for owners and a Limousine Tender for official transfers. In the years ahead Younique Yachts will be offering these new models as well as its custom built products to the mega yacht industry.”

“The new range reflects our philosophy. We listen to the end user’s wishes and use our joint knowledge and experience to make all these wishes come true.” Younique Yachts is developing the new range in cooperation with trusted partners Omega Architects (Frank Laupman) and Van Oossanen Naval Architects.

42m ALIVE yacht by Heesen Yachts completes her sea trials

November 20, 2014

42m ALIVE yacht by Heesen Yachts, featuring a Hull Vane®, has completed her sea trials with great success, exceeding the contractual speed by 0,5 knots. The sea trials of YN 17042 superyacht ALIVE have taken place in open waters in a slight sea state (0,70m waves) with 3-4 SW winds.

Motor Yacht Alive reached the remarkable maximum speed of 16.4 knots, exceeding the contractual speed by 0.5 knots!

The contractual fuel consumption prediction proved to be correct: 4000nm at 12 knots. Over 750 miles come free of charge thanks to her remarkably frugal fuel consumption, that is 30 per cent less than on a conventional displacement yacht.

This is an important achievement and statement for this Dutch shipyard, as Alive superyacht is the first luxury vessel equipped with Hull Vane®.

The Hull Vane® is an under water foil that harnesses waves to produce power; this in combination with the Fast Displacement Hull Form and conventional diesel engines produces remarkable results. Proven during independent research conducted by Van Oossanen Naval Architects at two of the world’s most respected hydrodynamic laboratories — Wolfson Unit and Marin — it is today confirmed at sea.

Following the installation of the generators and engines in the hull and the joining of the hull and superstructure last July, work was immediately started on the insulation, pipe work and priming. Most recently the interior fit out has begun. The interior has been pre-fabricated on site at the Mulder Shipyard by the in house team of carpenters. The propulsion system is ready and the last parts of the superstructure have also been delivered, including the deck furniture, hardtop and mast. The construction progress of luxury yacht BN100 is on schedule.

British design agency Claydon Reeves is responsible for both interior and exterior design of the 34 metre full custom built, steel displacement yacht and the naval architecture is the work of the Dutch Van Oossanen Naval Architects. The Mulder 34 metre will be built to superyacht standards. The Mulder has a GT from 315 tons and will be built under RINA LY3, MCA classification and Unlimited Range. She will enjoy many features that are usually only associated with far larger yachts, in both operations and design.
