"The average gives the world its continuance. The extraordinary gives its value."
Oscar Wilde (1854-1900)

CATAMARIS® is a manufacturer of custom-made blue water sailing-, motorsailing - and motor catamarans made of aluminium for owners who want something exceptional. Every newly manufactured catamaran is unique.

Customers whose requirements can no longer be met with series or semi-custom catamarans benefit from the perfect cooperation with our architects as well as our shipyard certified by "Germanischer Lloyd" and by " Bureau Veritas".

CATAMARIS® new constructions are based on the examples shown (Catmar Explorer 55 -78) or by new, individual "Full-Custom" designs (e.g. 64 - Full Custom) according to your wishes.

With flybridge or half-height, protected steering position or in a layout suitable for wheelchair users. With diesel engines or with diesel-electric hybrid drive. With reinforcements at the bow tips and waterlines against ice and flotsam.

Independent on all oceans

Whether anchored at the Costa Smeralda or passing through the NW passage, whether skiing and sailing expeditions in the Antarctic or island hopping in the Caribbean: All CATAMARIS® catamarans are perfectly equipped for explorer voyages to high and low latitudes. Due to the heavy-duty construction with integrated reinforcements at the bow tips as well as above and below the waterlines, they offer a high degree of protection against ice floes, containers and flotsam.

Uniquely large living areas on board

Not "off the rack"

"I was looking for something that was "not off the rack". A "custom-made" new construction designed entirely according to my wishes. A sailing catamaran and a motor catamaran, but both at the same time! As building material only aluminium. A smaller rig with furling sails that can be operated by me or my wife alone. And 2 powerful engines. The tank volume must guarantee a transatlantic passage”: CATAMARIS® has fulfilled these requirements of the owner with the new 64-full custom "Parana III".

NEW: "Green Power Supply" hybrid system for propulsion and electricity

After 2 successful test years with 4 large yachts and 15 commercial vessels, the innovative diesel-electric "Green Power Supply" hybrid system for propulsion and electricity generation is now also available for CATAMARIS® catamarans as an alternative to conventional diesel-engines. For eco-friendly and worldwide cruises.
More about "Green Power Supply"

NEW: Catmar Explorer 64 now also with protected helm station

Due to popular demand, the Catmar Explorer 55 is now joined by the Catmar Explorer 64 with a half-height, protected steering position. The entire sail control system is also centrally located at this helmstand. This offers the small crew more safety and an optimal communication.

NEU: 64 foot catamaran for wheelchair users

For a Bristish “disabled sailors association” and for an operator of sailing trips for wheelchair users we have developed 2 catamarans, each 64 feet long. Both are wheelchair accessible on all decks, cabins, saloon, flybridge, cockpit, dinghy and bathing platform. Convenient access on and off board by wheelchair is also possible at any time. The centralised sail handling is designed in such a way that a wheelchair user can perform all sailing manoeuvres even single-handed. Ask for the detailed specifications.

Sustainable, unique:
Aluminium with CATAMARIS®

Not all aluminium is the same: CATAMARIS® exclusively manufactures aluminium of class 5083 H 321/H111 certified by "Germanischer Lloyd, Bureau Veritas or Lloyd's Register". This material has the best resistance to corrosion and seawater.
More about the special benefits of aluminium.

No wind? Transatlantic range under engines

CATAMARIS® sailing, motor-sailing and power catamarans can be equipped with tank volumes that allow a range under engines of up to 3,000 Sm. This was successfully realised with the 64-FULL CUSTOM "Parana III". The 2,620 Sm from Las Palmas to St. Lucia can thus be cruised without sails in calm conditions if necessary.

My perfect ship

The Owner

I was looking for something "not off the rack". A custom-made new building, designed entirely according to my wishes. A sailing catamaran and a motor catamaran, but both at the same time! And as building material only aluminium. A smaller rig with sails that can be operated by myself or my wife alone under all circumstances. And 2 powerful engines. The tank volume must guarantee a transatlantic passage. After a long search, I arrived at CATAMARIS®.

The CATAMARIS® team developed a tailor-made concept with its architects, drew up the construction plans and provided me with the best shipyard. The successful maiden voyage with my "Parana III" led over 6,000 nautical miles under engines from Holland via the Rhine, Danube River, Danube, Black Sea, Eastern and Western Mediterranean, Portugal and Biscay and back to the shipyard in Holland where rig and sail were assembled. Currently I am heading for new destinations via Canary Islands further west into the world... At CATAMARIS® I have been provided with my perfect ship!

The founders of CATAMARIS®


Most catamaran shipyards offer series-produced ships that cannot be adapted to customer requirements at all or only to a very limited extent. Many shipyards cannot or do not want to do this either, as this disturbs the rational series construction.

Individual yacht building according to the customer's wishes - rather than according to shipyard specifications - is increasingly in demand.

This is why Chris Minnee, Rolf Kohlhas and Catherine Relandeau - all with decades of experience with catamarans - have founded CATAMARIS®.

We have the sensitivity to understand your wishes and requirements and to give them the utmost priority.

We're at the heart of shaping concepts and design, new constructions, construction supervision and delivery.

Our Mission

CATAMARIS® is your partner for planning, new building and delivery of "custom- and full custom made" deep-sea catamaran yachts.

A special unique selling proposition (USP) of CATAMARIS® is the readiness to meet all customer wishes as far as they are technically feasible and guarantee the safety of the construction.

CATAMARIS® is one of the few manufacturers which offer custom catamarans from 55 feet and larger. The partners of CATAMARIS® combine decades of experience in the multihull industry, they put their experience, expertise and knowledge at the service of customers who want something unique.

CATAMARIS® presents you with the following benefits and strengths:

  • Listening, responding to your suggestions
  • Guaranteeing a properly engineered and well thought-out complete solution from a single source Integration of expert skills from all yacht subsections
  • Networking of professional expertises from all yacht subdivisions
  • Independence, neutrality and confidence
  • Development of concept, awarding contract, project management, testing, delivery
  • Professional monitoring of the newly-built vessel and the construction costs
  • Straightforward handover of your new catamaran yacht

We have the sensitivity to understand your wishes and requirements and to give them the utmost priority. We work with you to select the right catamaran type and the most experienced architects, designs and the shipyard for your very own, custom-made project.

...place your highly individual dream into our experienced hands...

Catherine Relandeau

Catherine Relandeau

Born in 1964. Sailed on the Optimist aged 8, then on 420, 470 and Laser as a teenager. My one dream at this time was to spend time on boats.

This dream became true: I started my Bachelor's degree in languages (English and German) in 1985 at the Finance department of Beneteau Group. But I was so taken with the catamaran concept that I transferred to the Jeantot Marine shipyard in 1989, where I worked on the introduction of the now globally-renowned Privilege cruising catamaran. I then spent 20 years in international sales of this luxury catamaran, measuring up to 75 ft, to private individuals at Alliaura Marine.

Listening, showing understanding for the expectations of my customers, and helping them to achieve their dreams. I had fantastic experiences with a number of extraordinary personalities, such as Dennis Conner and Philippe Jeantot, and worked on various catamaran designs in accordance with client specifications. On my international travels to my customers, I discovered new brands, and I still enjoy sailing even more by the day (when I can find the time!)

I founded CATHYACHT International in 2010 so that I could offer my customers all the experience and expertise I had gathered within this market.

It was a natural evolution to establish CATAMARIS® in order to help a number of exclusive owners make their dreams of super-catamarans come true, using my dedication, experience and passion...together with my partners, Rolf and Chris!
