SPOTTED ON VPLP's WEBSITE

I found the pictures of HEMISPHERE mast in the news section of VPLP's website. The mast is 53 meter long and HEMISPHERE boosts a 44.2 m meters. She is the largest catamaran in the world and I thought production had stopped at DEREKTOR shipyard. I hope it is the sign the HEMISPHERE is still on the track and will be launched in a near future. We are all waiting for her.

Does any one of you have some news ?

MORRELLI AND MELVIN - NEW WEBSITE AND BLOG ONLINE

The california based design office has launched a new website and also, for those of you like me who are into RSS flux, a blog updated more often than their previous website and that's great news.

As I have stated in a previous post about reverse bows and the Aeroaycht 110, Morelli and Melvin have become kind of specialists in the design of such hull shapes. They recently took part to the BMW ORACLE trimaran amas design. The team contributed to Sailing Scuttlebut about the use of hydraulics and stored power in the America's cup.

DRACONIS BY YOUNG DESIGNER OF THE YEAR WORLD SUPERYACHT AWARD 2009 MAILA SPEITKAMP

The young German Designer Maila Speitkamp was awarded the Young Designer of the Year Award at the World Superyacht Award Ceremony held by Boat International in London for her catamaran concept nammed DRACONIS. Congratulations.



DRACONIS, a 43.6 meter luxury catamaran, was designed to host 12 guests with 6 crews. This amazing design features high tech wing sails which completely fold on the boat while motoring. Though defined as a sailboat with good upwind performances, DRACONIS can transform into a power boat and provide the best of the two world to the owner or potential charterers. The sails have the shape of a bird wings.

The deck layout is quite different as on a regular catamaran since there is no mast in the middle the deck is kept on a single level uncluttered platform from on side to the over.

I am not suprised she got the award there are so many yet possible and well thought new features on this catamaran.

AMERICA'S CUP DESIGNS PROVE THE AEROYACHT® 110 IS AHEAD OF THE CURVE

The hull shapes of the America’s cup challenger BMW ORACLE Racing and defender ALINGHI didn’t go unnoticed and will make a lot of ink flow. Both are using wave piercing bows.



The radical Aeroyacht 110 catamaran designed by Gregor Tarjan and engineered by Morrelli & Melvin had, since the beginning - reverse bows. Pete Melvin, from Morrelli and Melvin, who took part in designing BMW ORACLE, and Gregor Tarjan founder of Aeroyacht International, tell us why?Morrelli and Melvin 60 ' Mala Conducta - Photo Credit Billy Black


Gregor Tarjan: “Reverse bows make the water think the boat is longer. A regular shaped bow will make the boat hobby-horse because as the boat is dipping into the sea the shape of the stem will force it back up quicker than if the stern is allowed to pass deeper and more gentler into the wave resulting in more comfort, safety and yes wetter. I think reverse bows are the future for small racing boats (where a wet ride is secondary) and large yachts over 60 foot.” Of course the potential clients for a luxury super catamaran like the Aeroyacht 110 will be interested in performance but this single argument might not be enough to convince him to go for reverse bows. That is what Gregor Tarjan and Pete Melvin both answer when a potential client asks them why his yacht should feature a wave piercing shape.

Pete Melvin “To make it short and simple, wave piercing reduce pitching motions and hull resistance though waves. Pitching results in motion discomfort for passengers, increases hull resistance and reduces sail efficiency. We’ve been designing wave-piercing bows for quite a few years now both for racing and for cruising multihulls. It is quite interesting to see that Alinghi have developed a hull and bow shape quite similar to the A3 A-Class catamaran we developed in 2003. There were other wave-piercers prior to the A3 but the A3 has a very unique shape that has been emulated many times since then. We are involved with the BMW ORACLE team and had some input into their news floats shapes as well. Lots of R&D went into confirming what we already knew was a fast wave-piercing hull form. The shape of the bow and underbody of a wave-piercing hull is dependent on many variables so the best solution for one design may not look the same as another design. In fact, the F-18 cat is actually closer to the design requirements for a high performance cruising catamaran like the Aeroyacht 110.”



Gregor Tarjan and Pete Melvin have put all their experience, knowledge and energy to design the Aeroyacht 110, the most advanced cruising catamaran every created so far.

RAKU 30 M CONCEPT BY GRAINGER DESIGN

The Raku 30 m is a concept designed by the Australian Multihull designer Tony Grainger. He has designed many sports, crusing catamarans and developped the Raku Concept.


The most impressive feature of the Raku range is the use of flat monocoquespanels for the hulls except for the bottom hull. The panels are made of composite and foam or grain balsa cores. The Raku 30 m is the largest of the range and features a biplane configuration with free standing composite wing masts. The advance of the mast is that it leaves the platform openswith a lots of living, entertaining and working space. This 30 meter catamaran can be built with flat panels or with a more traditional process. The design really is a concept open to the clients wishes. It is a base for reflexion. It can be addressed to a private owner wanting something different or a charter company.

LAGOON 620 - TREND SETTER

The new, awaited LAGOON 620, was lauched last month. It is a great looking cat specially from inside. Let's have a look at the beautiful pictures by Nicolas Claris.

The LAGOON 620 is built with the infusion process. Lagoon has a lot of experience in this building technique. This should guarantee not only stiffness and quality but also a very reasonable weight to length ration and good sailing performance. The design is by famous VPLP, the designer of the Lagoon Range.The most amazing feature is the space on the boat both outside and inside. Outside, the flybridge is huge and hosts two steering stations for a better view on the sea, which is a first on a catamaran of that size (if I am not mistaken). You can relaxe on the fly, on the trampoline, in between the transoms, in the cockpit, or on the huge safo in the salon, so there are lots of places to get some privacy.
The interior is designed by famous multi-awarded designer studio couedel-hugon yacht design and it is a great success. The interior is very clear and uncluttered. Lots of light inside through the large French sliding window and the huges portholes. The kitchen is generous and fully equipped with a double access to the salon or directly on the transom which will be great for the crew to serve the guests. The LAGOON 620 is a great charter boat for a crew. The owner suite in the 3 cabins version is huge since it takes all of the starboard hull and has a private and direct access to the transom (like the kitchen on the other side). The beds are large, comfortable island beds.

The LAGOON 620 is available in a owners version with 3 or 4 cabins and in a charter version with 5.
The LAGOON 620 will be exibited at the September Boat Shows of Cannes, Southpamton, and the ISWA.

AEROYACHT 110 - The World most innovative super catamaran

Multihull passionate and expert Gregor Tarjan, founder of Aeroyacht International, and renowned designer Pete Melvin sat down together to think about what their dream luxury catamaran would be. They came out with many innovative solutions, some of them never seen on a multihull of that size.


In a previous post, I introduced a list of these innovations, like the Icon A5 amphibian plane “tender”, the reverse bows, the competition wing-rig, the semi-flybrigde... Let’s complete the list to show how well the Aeroyacht 110 concept was thought out.

A “Outside-In” design process. Most of the time yachts are designed the other way around. Large multihulls are loaded with equipment, staterooms and end up with two or three decks. Gregor says: "We first have conceptualized a pure sailing machine with a beautiful streamlined shape and then estimated the weight for a high-end, open plan luxury interior. Instead of fitting 6 small staterooms we prefer to offer our clients three large VIP suites in a fast sailing machine"

“Soft-chine” hulls. Multiple Chines hull can be seen on racing sailboats, fast motor yachts and tenders. They increase the yacht structure stiffness, stability, performance thanks to less wetted surface, and improve esthetics. On the top of that Morrelli and Melvin have applied all their knowledge in fast hulls and bows out of the water design. The entire forward section of the Aeroyacht 110 hulls are forced up and will come out of the water keeping resistance to a minimum and increasing surfing capabilities

Asymmetric dagger boards. They are seen on smaller size catamarans but never before on a 110 footer. Retractable dagger boards increase windward performance and safety at sea. In the downward position, they enable the Aeroyacht 110 to sail close to the wind. In the upward position, the boat experiences less resistance and really "flies". The asymmetric boards also prevent the Aeroyacht 110 from tripping over the waves since the yacht offer no resistance and can slide sideways. They are also a great feature to reduce the draft and access really beautiful and private anchorages.

Aeronautical engineering.
The design team in charge of the Aeroyacht 110 at Morrelli & Melvin is made up of aeronautical engineers and structural designers. They have made the most out of the same tools used to develop aircrafts structures like complex computers programs that model Computational Fluid Dynamics (CFD) and Finite Elements Method (FEM). They succeeded in keeping the structure as light as possible, yet strong enough to face the roughest sailing conditions.

All this innovations were aimed at creating a super catamaran with a speed potential of over 32 knots and effortless cruising at 20 knots, in supreme yacht comfort and safety.
