ACCORDING TO YOUR PREFERENCES

Plan together with the architects, have a "full-custom" design created according to your specifications and have it built at shipyards in Europe that are experienced in the construction of large multihulls. Catamaris® accompanies you throughout the entire process.

The architects translate your ideas into an attractive, harmonious exterior and interior design with no limits. Using certified aluminium or high-tech composites, the shipyards in Europe build your yacht with the finest interior and exterior fittings. The result is a masterpiece of maritime craftsmanship according to your ideas.

The multihulls shown on this website are a selection of yachts already built and of new designs that can serve as inspiration for you.

Exterior Design

The architect and design office COSTE DESIGN has been at the forefront of the multihull market since 1990.

Jean-Jacques Coste has a high level of expertise in the development and construction of some of the world's largest catamarans made of carbon fibre, high-tech composite and certified aluminium.

The following design examples illustrate the different style variations.

Interior Design

The interior design can also be customised together with the interior designer Jean-Jacques Coste according to your personal preferences.

Contemporary or classic, functional or luxurious, according to your personal ideas.

The following examples show realised interior designs and drafts of different styles. They also illustrate the outstanding construction quality.

Materials & Surfaces

Materials

The naval architects place great emphasis on the selection and use of materials that meet high standards of yacht functionality and luxury. An optimal balance between performance and weight is achieved through an efficient design and construction process.

The catamaran yachts are constructed using carbon fibre (sandwich epoxy/carbon/glass/PU foam in infusion process) or aluminium.

But not all aluminium is the same: The Catmar Explorer® catamarans are made of class 5083 H 321/H111 aluminium certified by "Germanischer Lloyd, Bureau Veritas or Lloyd's Register". This material has the best corrosion and seawater resistance. High strength, stable, temperature resistant from -270 degrees to + 80 degrees, non-combustible. Read more about the advantages of aluminium in shipbuilding here.

For some of the larger BLUE COAST catamarans (92, 95-1, 101ft.) Sealium® Aluminium marine grade is also used. Learn more about Sealium® here.

Interiors and design meet the latest requirements for comfort and luxury, using lightweight materials and state-of-the-art joinery and decorative materials to suit the client's design preferences.

Surfaces

The examples show some successful custom-made products and illustrate the excellent workmanship even in the smallest detail.

Sustainable and eco-friendly

Catamaris® and his partners commitment to the sustainable reduction of the carbon footprint focuses in particular on the materials used.

In Catmar® Explorer catamarans, these components can be recycled:

  • Hulls and superstructure built of certified aluminium
  • All components made of stainless steel (Inox)
  • Engines, gearboxes, shafts, propellers, generators, water makers
  • Cork for deck coverings
  • Furniture construction, upholstery, safety glazing of the windows, fireproof insulation of aluminium hulls und superstructure
  • Rig and sails: mast, boom, shrouds, spreaders. The new, fully recyclable „ONE“ sails certified with the ISO 14040 life cycle assessment

Most of all materials applied on our Explorer catamarans can be recycled and reused in an environmentally friendly way at the end of their life.

Catamaris® also makes a significant contribution to reducing CO2 emissions during operation.

On Catmar® Explorer catamarans, these components reduce CO2 emissions:

  • Engines, gensets and equipment that meet the high EU standards in terms of CO2 emissions, for example.
  • With our optional diesel-electric hybrid propulsion systems, a further significant reduction of CO2 emissions into the environment is achieved.

With a Catmar® Explorer catamaran built in a sustainable and eco-friendly way, you make a positive contribution to reducing your CO2 footprint.

Technologies & Craftsmenship

In an age of impersonal, automated mass production, the architects strives to create the finest handcrafted products using modern, computer-aided design and high-end construction techniques. The immaculate detail and finish of a yacht, inside and out, can only be achieved through skill and dedication.

The naval architects use, among other tools, CAD 3D technologies for the technical and interior design plans.

The architecture and hydrodynamics of the ship are designed using Computational Fluid Dynamics (C.F.D.), tank tests and structural calculations are carried out and calculated using F.E.A. (Finite Element Analysis) to obtain the best possible structure.

In this way, the technology and systems are tightly integrated into the overall design of the ship without affecting the flow of life on board. These studies are the result of the architects' enormous experience in all aspects of design, construction and from sailing multihulls.

Shipyards

All yachts are built in Europe by partner shipyards, which are recognised worldwide for their high construction quality. They are experts in the processing of high-tech composite materials and in aluminium certified by Germanischer Lloyd, Bureau Veritas or Lloyd's Register, as well as Sealium® aluminium. They meet the strictest and most demanding classification requirements.

Quality in all areas means much more than just the hulls. The finish throughout the new yacht, both inside and on the outside, exudes the utmost refinement that everyone can see, feel and admire.

The same high standards also apply to the many invisible areas and components, from the bilge pump to the fuse box and masthead. This quality is impressively demonstrated by the fulfilment of strict classification criteria, among others from ABS, BV, LRS, MCA and RINA.

Green Eco Power

Leading the way in on-board renewable energy: The field-proven "Green Eco Power" diesel-electric hybrid energy system.  

After successful test years with 4 large superyachts and 15 commercial vessels, the innovative diesel-electric hybrid propulsion and energy system "Green Eco Power" is available for catamarans as an alternative to conventional diesel engine propulsion. For environmentally friendly and worldwide cruising.

The "Green Eco Power" system is designed to significantly reduce diesel fuel consumption, resulting in lower emissions of NoX (nitrogen oxides) and Co2 (carbon dioxides).

Other advantages include the system's high reliability, low noise and vibration levels, minimal maintenance intervals and worldwide access to protected areas that are only allowed for electrically powered yachts.

Other measures taken to generate eco energy for the yacht can include:

  • Optimising the upper deck as large as possible for solar power panels.
  • Install wave generators to regenerate power while sailing.
  • Installation of wind generators. The new vertical wind generators with modern design are very efficient and silent.
  • Installation of a heat recovery system for the exhaust air of the air-condition to preheat/cool the fresh air.
  • Using lake water at the deepest point under the boat to produce cold water to cool the air in the boat.
  • Installing a larger shore connection to charge batteries and diving compressors in a shorter time.

Other measures taken to save energy consumption are:

  • Extra efficient insulation on all exterior walls and high-quality insulated windows.
  • Avoidance of dark colours that attract a lot of heat.
  • Use of cork deck to keep deck temperatures low.
  • Low overall weight of the catamaran to keep drag low.

We are convinced that with the right eye for details and the right pursuit of all possible measures, we can create a ship that is almost completely self-sufficient and climate neutral without using fossil fuels.

A look into the future

The research and development of fossil-free energy sources is progressing rapidly. The architects are constantly following and monitoring some new, alternative developments and approaches in the field of CO2 neutral power generation systems and renewable energy and will inform you here from time to time about possible progress.
 

CONSTRUCTION DIARY 72 FT. EXPLORER CATAMARAN

A Spanish company is having a custom-made powerful 72 ft. Catmar Explorer ocean-going cruising catamaran yacht newly built by Catamaris®.

The requirement was for a modern yacht design suitable for sea exploration in the oceans and for charter with crew as well as for circumnavigation.  A modern yacht design was required that was suitable for expeditions for marine science expeditions in the oceans and for crewed charters, as well as for circumnavigation. This was successfully planned in collaboration with the architects and designers of Catamaris®, even a laboratory is included in the interior layout.

Using the example of the seaworthy new construction of this Catmar Explorer 72 Cruiser Catamaran made of certified aluminium at our shipyard in Harlingen, Holland, we report on the progress of the individual construction stages.

The construction diary is updated continuously.

2023 January - March

After the precise engineering calculations by our naval architects and designers at Marimecs, the certified aluminium raw material was ordered and then cut into hundreds of dimensionally accurate components by a specialised company and delivered to our shipyard in January. There, the construction of the hulls began. You can see very clearly that the close-fitting frames ensure that the hulls are very stable and perfect for bluewater cruises.

After completion of the hulls and deck, the structure will be turned 180 degrees and the deckhouse and flybridge will also be manufactured from certified aluminium.

At the same time, the construction of the furniture based on the modern interior design began. To this end, one of the best specialist furniture companies for superyachts in Holland first produced a 1:1 model of the aluminium structures, into which the entire interior furnishings are now gradually being manufactured and installed. The finished furniture will then be taken from the raw model and fitted precisely on board the catamaran in our shipyard.

2023 April-August

The most time-consuming work is coming to an end: hulls, deck, superstructure and flybridge will be finished by the end of August.

Here you can see some first impressions of the finished components. The "horseshoe-shaped" clamps were used to align the components exactly before welding and will of course be removed.

Then all the outer surfaces are sanded several times to get a perfectly smooth surface.

Then the hulls and the other components are turned, the deck, the deck structure and the flybridge are put on and welded together homogeneously and torsion-free.

The finished furniture for the hulls is stored and waiting to be installed. At the same time, the furniture for the saloon, cockpit and flybridge is already in progress.

The "Wedding"

Video - Turning hulls and deck

Maritime Masterpieces

On 6 October 2023, the "wedding" between hulls, deck and superstructure has taken place. 

January -April 2024 

The water and diesel tanks, pipes, tubes and cables are currently being installed inside. The very strong structures of the frames and stringers are still clearly visible. The fireproof SpreFix™ insulation for heat, cold and sound insulation will then be applied to all the exterior walls and ceilings. The "hidden qualities and assets" are then no longer visible. Outside, the grinding work for the exterior design and the preparations for the add-on parts on the mast are carried out.

Catmar Explorer 72 ft. was moved from the structural hall to the interior finishing hall on 14/02/24. The already finished roof of the flybridge had to be removed because of the hangar door.

The work continues with the engines, generators, air conditioning, navigation equipment, laboratory equipment for marine research, kitchen and bathrooms. The completed furniture will be installed from around May. As soon as the catamaran is launched, the mast will be placed and trimmed and the sails delivered.

Now is therefore the ideal opportunity to find out about the high quality of workmanship and the "hidden values" of our Explorer catamarans on site. Convince yourself now of the high quality in detail and the stable construction - visit us without obligation at the shipyard in Harlingen/Holland. On the same day, it is also possible to discuss your plans and ideas with our partner architects on request. We will take care of hotel reservations and transfers if you are travelling to Amsterdam by plane or train. Make your appointment now to visit the shipyard in Harlingen, Holland.

The Catamaris® Explorer 72 is expected to be completed in summer 2024. This will be followed by 4 weeks of sea trials, familiarisation and trimming before the yacht is expected to set sail for its destination, the Canary Islands, from September. It is possible to charter a cabin during the transfer to the Canary Islands or even there and sail along for one or more days or weeks. Give us your preferred dates here to discover this new catamaran from Catamaris® at sea.
