Afscheid van vijfvoudig Nederlands kampioen Lemsteraak BS2



Na 3 dagen racen onder varierende omstandigheden kwam ook dit jaar de Buikschuiver II als Nederlands Kampioen over de streep.  De strijd om de titel was dit jaar extra spannend door sterk zeilen van de jonge bemanningen van de Maasvogel (tweede plek) en de Marie Charlotte III (derde plek) en door toedoen van het weer. Zo finishten er in de zaterdagochtendwedstrijd slechts vier schepen binnen de tijdslimiet omdat de wind weg viel. De lange-baanwedstrijd op de zondag werd bepaald door een enorme windshift in het laatste rak, die nog voor een aantal wisselingen in de stand zorgde.

Ondanks dit alles wist Peter Houtzagers als schipper van de Buikschuiver II de titel voor de vijfde maal op rij binnen te halen. Deze vijfde titel betekent helaas ook het afscheid van Peter en de BS2 in de top van de Lemsterakenklasse. Hij wil zich meer gaat richten op zijn gezinsleven en zijn bedrijf Sailmon.  Peter heeft met de BS2 het lemsteraken-zeilen naar een hoger niveau weten te tillen en andere teams weten te pushen tot vernieuwing van schepen en verjonging van bemanning, wat uiteindelijk de klasse zeker ten goede zal komen.

Naast het afscheid van Peter Houtzagers was er ook het afscheid van Ruud van Hilst met de Wadwaai. Na meer dan 30 jaar aanwezigheid in de VA-klasse, laat Ruud nu een motorjacht bouwen bij de Workumer Jachthaven.

Er is nog een mogelijkheid Peter en de BS2 te bewonderen, want komend weekend (23 en 24 september) zal de Hylper Hurdsilerij voor de tiende maal plaatsvinden. Hier zal Peter Houtzagers met de BS2 voor de achtste maal succesvol proberen te zijn. Deze twee dagen wedstrijdzeilen, met daarnaast een geweldig walprogramma in de avond, beloven een mooie afsluiting te worden van het wedstrijdseizoen van de VA-klasse.

OCEAN Independence USA to represent new Van Oossanen and Fiorentino Fast Displacement XL®-300


Van Oossanen Naval Architecture joins forces with Milanese designer Federico Fiorentino for a new 47.5 metre superyacht concept. Cristiano Gatto will be responsible for the interior design.  The XL®-300 Sport will be taken into sales by Thom Conboy, President of the Americas of OCEAN Independence. Thom states: “It’s really exiting to be working with Van Oossanen, Fiorentino and Gatto on such a cool project which has an amazing potential for the US market.”

Named Fast Displacement XL®-300 Sport, this motor yacht is based on Van Oossanen’s innovative new Fast Displacement XL® hull form and operates with a total interior volume of less than 300GT. The new Fast Displacement XL-300 Sport (47.5m / 299GT) allows a top speed of 29 knots.

The Fast Displacement XL® concept is a radical evolution of the famous Van Oossanen patented FDHF (Fast Displacement Hull Form). The main advantage of the XL® according to Perry van Oossanen is that “it offers maximum length, superior comfort and the highest performance. It gives the possibility to create the longest yachts ever within the 200,300 or 500GT boundaries.” An increase in length of 20% will result in 10% more interior space and 30-40% more exterior deck area, creating unprecedented exterior lounge, pool and sun bathing areas.  “So it is possible to have a 45+ metre yacht, reaching close to 30 knots, with a 6ft draft, for less than 300GT”, Perry explains.

The exterior styling of the Fast Displacement XL®-300 Sport was provided by Fiorentino. Federico:  “I gave this yacht a contemporary sleek and sharp look that perfectly combines with the lightness of its generous open spaces. An aggressive attitude reflects the high performance hull that lies below the waterline.” The famous interior designer Cristiano Gatto has been approached to create the interior décor for this sleek cruiser.

Accommodation is for ten guests split across five staterooms, including a main-deck owner’s cabin as well as three doubles and a twin cabin below decks. The crew quarters would be situated in the bow, accommodating six people in three en-suite cabins.

Key features include a superyacht helipad on the foredeck, an aft-deck infinity pool and a side-loading garage that is large enough to house two Jet Skis as well as a 6.25 metre tender. Van Oossanen adds that this design could be built from an aluminium hull and superstructure to Lloyd’s and ABS standards, compliant to LY3.

Power would come from twin 2600hp MTU 16V2000 M96L diesel engines for a top speed of 29 knots and a maximum cruising range of 3,500 nautical miles at 12 knots. Meanwhile, a pair of gyroscopes with active interceptors would ensure a smooth cruising experience for all those on board.

Mulder’s Delta One exceeds expectations on sea trials


The recently launched Mulder ThirtySix, motoryacht Delta One, has successfully completed her sea trials off the coast of the Netherlands, from the marina of Scheveningen.

With naval architecture by Van Oossanen, exterior design by Claydon Reeves and interior design by Vickers Studio, the full aluminium M/Y Delta One exceeded expectations. Her patented FDHF hull shape behaved very well at sea, with winds up to 6 Bft on the North Sea during sea trials. Driven by twin Caterpillar C18 1.150HP engines, her top speed of 16.8 knots is matching calculations, as expected. At a cruising speed of 15 knots with an engine load of 67%, M/Y Delta One performed amazingly comfortable.

Due to the great synergy between her owners, IYR as owner’s representatives, the crew, Mulder Shipyard, Van Oossanen and Claydon Reeves + Vickers Studio, the Gross Tonnage of 298 has been meticulously optimized at all areas on board. Studious engineering combined with the strive to top-quality of all parties involved, the 36.00 metre yacht offers generous space to ten guests in five luxurious designed staterooms. The efficiently created tenderbay area features a Williams 625 Dieseljet, two Yamaha GP1800 jetski’s, Seabobs and extensive windsurf-gear.

Mulder Shipyard will present Delta One at the Monaco Yacht Show from 27-30 September.


Heesen’s first hybrid-propulsed FDHF motoryacht ‘Home’ exceeds expectations!


On 1 July 2017, the world’s first Fast Displacement motor yacht equipped with hybrid propulsion was delivered by Heesen to her Owner in international waters.  This 50m all aluminium motor yacht below 500GT with shallow draft, underwent intensive sea trials in the North Sea for five days in calm sea conditions, with waves of up to 0.5m and light breeze.

The results are impressive: not only has HOME easily exceeded her contractual maximum speed of 16.3 knots in the traditional diesel engine mode, but also expectations in her hybrid ‘silent cruising mode’. Thanks to two 127kW water-cooled DC electric shaft motors, she exceeded the predicted speed of 9 knots with noise and vibration levels well below the specification levels.

HOME is not only ultra-quiet, but she is also extremely fuel efficient. At 12 knots, she has a fuel consumption of 98 litres per hour (excluding generators) and at 10 knots in hybrid mode this further reduces to a staggering 45 litres per hour, which for a 50m yacht, displacing 295 tons and with a Gross Tonnage of 499, is an outstanding achievement.

This impressive performance is achieved with just two MTU 12V 2000 M61 engines of 600 kW each, which are smaller than those typically fitted on a yacht of this size. This once again proves the remarkable efficiency of Van Oossanen’s FDHF (Fast Displacement Hull Form).  With a particular attention to weight control, HOME is predicted to achieve a transatlantic range of 3,750 nautical miles while cruising at 12 knots, despite carrying just 45,000 litres of fuel. This is  further underlining the remarkable efficiency of the FDHF (Fast Displacement Hull Form).

Despite being powered by relatively small engines for her size — twin 804hp MTU 12V 2000 M61s — HOME will still achieve a respectable top speed of 16.3 knots when powered by her main engines and the diesel-electric propulsion system will allow for silent cruising at up to nine knots. Smaller engines mean the yacht will also be more spacious, with less room taken up by the engine room. Interior stylist Cristiano Gatto worked closely with the Owner to create an interior décor that boasts a sophisticated linear design based on a two-tone palette.

The striking profile was designed by Frank Laupman of Omega Architects  and is considered a design delight with her vertical bow and characterising spray rails, to her stern with a large fixed swim platform, wide sweeping stairs leading to the main deck and floor-to-ceiling glass windows.

HOME will début at the Monaco Yacht Show from 27-30 September 2017.

Heesen Yachts’s Project Antares: FDHF® hull and superstructure joined together


On May 14, 2017 the joining of the hull and superstructure of Project Antares, and the installation of her two MTU 8V4000 M63 engines, took place at the Heesen Yachts facility in Oss.

Project Antares is a 55m steel-hulled FDHF® vessel that was sold just over four weeks ago to a very experienced American yachtsman. She will have some special features to carry out her role as mothership to the owner’s sport fishing fleet, such as the possibility to re-fuel and re-charge two sport fishing boats, allowing for several days out at sea.

Moreover, Project Antares boasts a major difference from her equally beautiful sister ships: an owner’s apartment that is 30 per cent larger, having been extended from 62 to 80 sqm. Italian designers Francesco Paszkowski and Margherita Casprini are now working closely with the owner and his team to personalise the interior design of his new 740GT vessel.

Project Antares has now entered the outfitting phase and will be ready for delivery to her owners in November 2018.
