Yacht news

On the morning of 03 May 2015, the large private yacht Kibo (now Grace) was at anchor off Portals Nous in the island of Majorca. A party of 6 guests were on board.As was the normal practice when guests were on board, the work day started early by cleaning the exterior of the yacht and preparing various equipment and facilities for the use of the guests. It was decided that this would be a suitable opportunity to clean the rubbing strakes (known as “rub rails”) on the yacht’s hull approximately 3m above the waterline. This work involves a crew member working over the side of the yacht supported by a safety harness and a “bosun’s chair” that were secured to the yacht’s bulwarks. A deckhand / assistant engineer (“the Deckhand”2) was chosen for the cleaning duties and commenced the overside work, under the supervision of the Chief Officer (C/O) and the Third Officer (3/O).After working over the side for approximately 50 minutes, the Deckhand fell from the worksite into the water and sank below the surface. An on board rescue was commenced, and the Deckhand was recovered from water. The time from the Deckhand falling from the worksite to being recovered back on board the yacht was approximately 13 minutes. First aid was administered, and an ambulance was arranged from shore. With first aid continuing, the Deckhand was transferred to shore in the yacht’s tender where he was transferred to a local hospital for treatment.Due to being deprived of oxygen while under water, the Deckhand suffered hypoxic brain injuries and was left severely disabled. On 07 June 2017 the Deckhand died of bronchial pneumonia brought on by his immobility following the accident. A ruling of accidental death was recorded following an inquest at Birmingham Coroner’s Court.The investigation found that the primary cause of this accident was poor working practices on board and a failure to follow the yacht’s documented safety management system (SMS).

Over its 40-year history, Heesen has developed a reputation for building cutting-edge superyachts that have pushed boundaries in design, speed and efficiency. From record-breakers such as Octopussy to more recent innovators such as Galactica Star, Galactica Supernova and Home, Heesen’s facility in Oss continues to play host to remarkable superyacht projects.The latest project to draw on this extraordinary heritage is Cosmos, an 80.7 metre aluminium superyacht that is set to push the boundaries even further. With a designed top speed close to 30 knots and an efficient cruising speed in excess of 20 knots, Cosmos will use a development of the Fast Displacement Hull Form (FDHF) coupled with innovative construction and advanced propulsion solutions to set new standards for large aluminium yachts. Although the keel-laying ceremony is due to take place later this year in May, this is not the start of the project – indeed, an extraordinary amount of design and testing has already been undertaken and completed.The proof-of-concept and testing process has comprised several stages, starting with the base naval architecture of the vessel and its hull form, progressing through extensive computational fluid dynamics (CFD) work and physical tank testing of a scale model, and culminating with the design of the propellers and rudder system. For these aspects, Heesen has drawn not only on the expertise of its in-house design and engineering department but also that of long-standing partners Van Oossanen Naval Architects, and propulsion specialists at Rolls-Royce.The first stage was to develop the FDHF concept and ensure not only that Cosmos benefitted from the efficiency and speed gains of the design, but also that the yacht could retain inherent stiffness – a challenge because Cosmos features all-aluminium construction in order to achieve the client’s desired maximum speed of close to 30 knots. The solution was for Heesen to develop the Backbone® – a method of construction that could deliver the required stiffness in the yacht without adding weight that would have impacted on the yacht’s performance. Such has been the success of the design that the Backbone® has now been patented.A 3.7m scale segmented model of the yacht was built to use in physical tank tests at the Wolfson Unit in Southampton. After initial data on hydrodynamics, resistance and speed had been gathered, the model has been radio-controlled and self-propelled in order to measure the various bending forces acting within the hull and to prove the Backbone® concept. That provided valuable data for fine-tuning the structural design and to further optimise the construction method.For such a large aluminium yacht, it is particularly important to know the real forces created by the sea on the hull, not just to meet Lloyd’s Register requirements but to exceed those and construct the boat to the highest loads that could be encountered. Using the FDHF design and the Backbone® for such a large aluminium yacht requires a slightly deeper keel depth, but this actually brings further benefits. Due to the slightly increased draft Project Cosmos has a very low block coefficient, which means that the underwater body is very slim with nice verticals in the aft ship area, for an optimal flow of water towards the propellers. This results not only in improved performance but also in higher efficiency, ensuring fast cruising with comparatively low fuel consumption.<iframe width="1067" height="600" src="https://www.youtube.com/embed/RgjWgN0ESCg" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>Refining the propeller design is the ongoing job of research and design engineers at Rolls-Royce. Alongside the propeller design itself, the Promas system – where propeller and rudder are integrated into a single unit to optimise hydrodynamic efficiency – has been implemented in the design. Rolls-Royce engineers started by gathering CFD information of the water flow towards the propeller. Then the design process began with Rolls-Royce proprietary software: different iterations of propeller and rudder design were tried before arriving at the optimal solution, which was then tested in physical experiments. <iframe width="1067" height="600" src="https://www.youtube.com/embed/h3HsopvR6Qs" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>By creating a 1:11 scale model of the Promas rudder and propeller in the test tank facilities of the Rolls-Royce Hydrodynamic Research Centre (HRC) in Kristinehamn, Sweden, the propeller design was fine-tuned not only to ensure the speed and efficiency requirements are met, but also that any potential problems with cavitation can be eliminated. Cavitation is essentially where air bubbles form in the flow of water around and behind the propeller. It is particularly challenging at high speed, and as well as affecting performance it can also have severe impacts on noise and vibration – a critical consideration for any superyacht project, especially for one close to 30 knots! Cavitation issues were identified and eliminated by adjusting the rudder design. Finally, the tests proved that the propeller performed above expectations.Project Cosmos will feature variable pitch propellers that will enable the yacht to handle both impressive cruising speeds in excess of 20 knots, as well as reaching a maximum speed close to 30 knots – a considerable achievement for an 80-metre superyacht. With the hull design optimised, the construction engineering finalised and the propulsion system going through the last stages of testing, Cosmos is already proving a milestone project for Heesen and the teams involved.“Project Cosmos is raising the bar once again not only for Heesen, but for custom aluminium yacht building in general,” says Arthur Brouwer, CEO of Heesen. “Both from a technical standpoint and from a performance point of view we are pushing boundaries. Not only has this 80.7m project been designed to reach close to 30 knots, she has been designed for fast, 20+ knots cruising in an efficient manner. The solutions we have implemented to meet all these requirements are once again driving superyachting forward – just as Heesen has done with innovative and ground-breaking projects throughout its 40-year history.”

Dutch shipbuilder Heesen started year with the launch of YN 18455 Project - 55m superyacht Antares. Project was sold in May, 2017 to an American owner and now is heading to the North Sea to undergo her rigorous sea trials. <blockquote class="instagram-media" data-instgrm-captioned data-instgrm-permalink="https://www.instagram.com/p/Bsgy-59hV0P/?utm_source=ig_embed&amp;utm_medium=loading" data-instgrm-version="12" style=" background:#FFF;

Heesen are active in 40-60m yacht segment, but they are more focused now on 50-60m yachts, as they see their potential there, as well as fully-customized yachts up to 80m.

Italian shipyard Rosetti Superyachts and Italian designer Giovanni Ceccarelli made a collaboration and created two supply vessels concepts measuring 35 and 50 metres. "I wanted to create an original exterior profile distinguished by clean, essential lines that eliminate superfluous elements to arrive at a truly timeless design.” Giovanni Ceccarelli, a life-long sailor and yacht architect, loves to start from scratch with a hand sketch when he begins a new design for a shipyard or owner.The new 35m Supply Vessel concept will be built from steel and aluminium together to combine comfort and efficiency. The steel hull forms provide low hydrodynamic resistance. Aluminium for the superstructures and composite materials for the top deck, in order to ensure optimal weight distribution and a low centre of gravity which reduces motions and increases comfort under way.The interior general arrangements offer an owner’s stateroom on the upper deck, with 180-degree views aft through the full-height glazing and a private terrace. Inside, there’s a spacious main salon with dining area; and the forward galley can be directly accessed from the crew quarters. Four ensuite cabins provide comfortable accommodation for 8 guests, on the below deck."On the new 50m Supply Vessel Yacht, hull and superstructures are part and parcel of each other, much like in sailboat design. This is not a simple exercise in ‘redressing’ a standardised platform: the hull lines and the topside's ones are inextricably linked together to give continuity to the whole."The 50-metre concept has a beam of nearly 10 metres, which offers even more interesting layout solutions. The main deck is arranged on two levels and covers a total area of 170 sq/m, including a 13 sq/m infinity pool and expansive beach club. The pool is heated so it can still be enjoyed as a hot tub in colder climates. Alternatively, the space can carry toys or a mini submarine. The tender is housed inside a dedicated garage.”Like on the 35-metre concept, the main deck features a generous open-plan lounge and dining area separated by the staircase and integrated bar unit. The owner’s suite is located on the upper deck overlooking the aft deck. The sun deck is equipped with a Jacuzzi, dining and relaxation area.

63-meter superyacht North Star has been recently launched in Turkey. Espen Oeino has been responsible for the exterior design of the yacht, while RWD designed the interior. With the beam of 11.5 metres and more than 1400 GT volume, accommodation on board is for 12 guests in 6 cabins, with the crew quarters for 17 people.Simon Goldsworthy of Edmiston, said : "The owner intends to put her on the charter market with Edmiston this summer, and with her massive volume and a stunning interior, she’s sure to prove very popular with charterers. Once she has been fully sea-trialled and delivered, the intention is that she will make her yachting industry debut at the MYBA charter show in April.”
