Owners, buyers, sellers, crew, colleagues, the different partners who work with me are strong and sensitive assets for me : the relay of their experience and their testimonies are important, especially when this concerns very special VIP ...


These are real stories, written with emotion, happyness, authenticity, and sometimes stressfull !

What a pleasure to work with Catherine who led the acquisition of our boat (and the sale of our counterpart) masterfully. Catherine knows all the
the sale and purchase of a boat, which despite the pressure on both sides, is often a difficult period.
Since the first contact, efficiency, advice, professionalism and speed of
reaction were at the rendezvous, not to mention a dose of humor and conviviality, to that everyone feels comfortable in taking full charge of the sale/purchase, regardless of the interests of the participants. We know that this view is certainly shared by former owners of the boat for spending time with them when taking over.
The folds were ironed, the hooks (few) quickly flattened to obtain a
perfect agreement until the final signature.
Catherine was present from beginning to end, always available, always after an email, a conference call or a conversation over the phone.
We can only recommend Catherine as a broker, whether you are a buyer or
seller, it will take into account the interests of all so that the transaction takes place at best from start to finish.

A dream came true.
We visited Les Sables d’Olonnes at the beginning of this year (2023) where Catherine had shown us a catamaran. The first impression was really wonderful, both from the used ship and from an ambitious and very professional broker. Of course we needed some time because it's obviously a big decision. From then on, Catherine took us by the hand every step of the way and gave us the security to make the right decision. It was an “all inclusive” package. Starting with the coordination, some conversions, guarantees and warranties, handling the registration and arranging a professional delivery to the Mediterranean. Before, during and after our first season, with the entire family, we could always count on Catherine. I could say many more things, but instead I would like to thank you again for the perfect, ongoing support and the resulting friendship.

Catherine was Amazing …!!!!!! Every aspect or detail in purchasing our Yacht was handled with efficiency and grace. Buying a significant investment in a vessel from 4,000 miles away was a very stressful task. Catherine and her team were there at every step. We could not have done this without them. I would highly recommend Catherine and her team for when you need a professional and caring partner.

With Catherine i bought my boat in 2015 and was always in Contact with her until now when I sold it in 2022. All what I can say is a phantastic performance, very charming and convincing both parties! Satisfaction is left on both sides, seller and buyer.

Sometimes there where difficult constructions of Registrations, Customer Services , part supply or service issues to solve. Catherine with her superb knowledge out of her experience with Alliura Marine and Privilege Marine and other Catamarans brands managed these problems with ease. Catamarans is her dedication and life. Her worldwide personal network helped us also in the Caribbean to find the right places and Persons to get the things done. Simply a wonderful experience to know her and to work with her !

"I had the pleasure of working with Catherine as the buyer of my recent boat. She was very helpful and professional, and went the extra mile to make the deal happen against challenging schedules and circumstances. I would definitely work with her in future deals"

Alon P. (Israël)


We bought our catamaran with confidence through Catherine Relandeau CATHYACHT INTERNATIONAL . It is with the same Confidence that a few years later after our journey to Polynesia we entrusted him with the sale of it.  

His professionalism, his perfect knowledge of the multihull, his availability, his integrity and above all his innate sense of the relationship between seller and buyer have met all our expectations. Benevolent efficiency was present at all stages of the transaction.

The multihull is its Passion - Thanks Catherine !

Milena and Patrick B.


I have concluded and just finalized through CATHYACHT the purchase of a 2017 Lagoon 52S with a residual LOA. All stages of the process were carried out in accordance with what was described and agreed upon at the outset with CATHYACHT. I commend Ms. Relandeau for her thoroughness, professionalism and efficiency, which played a key role in the successful conclusion of the negotiation, the transaction, and finally the successful completion of the formalities. Let her be thanked here.

Potential sellers or buyers will find CATHYACHT a very professional and trustworthy broker.”

​Catherine has managed to create a relationship between buyer and seller which is exactly what it should be. Fair, sensible, considered, friendly and professional. All underpinned by integrity. She went the extra mile(s) to assist in something completely new to me, helped me through the process and provided sensible, sage and accurate advice at all times. This has continued post purchase without any financial benefit. At every turn I felt she was representing both parties in a bi-partisan fashion.
If I sell my boat I would use her services. If I bought another I would use her services. She gets my unreserved recommendation.

​My wife and I entrusted the sale of our trimaran Neel 51 to Catherine because of the good feeling we had together during her first visit on board in addition to a recommendation made by our Maritime Law Council.
The contacts with different brand agents had not convinced us as much in the relationship as in the valorization of the boat.
Your enthusiasm shows a great confidence in you thanks to a long experience and a perfect control of the many stages of the transfer of property. Collaboration is also facilitated through a network of effective technical and legal partners.
Your responsiveness and availability are valuable assets, you are a true conductor passionate to carry out a boat sale internationally.
Thank you Catherine

Thank you Catherine for your huge assistance in the all steps of our deal, with the problems we faced to and the deadlines sometimes difficult to manage ..

Indeed I join Patrick concerning Catherine in his assistance, because the sale of this type of boat requires a good orchestration.  
Regarding Maajicat we were able to test it last week and it seems to fit perfectly with our long course travel plans.

We first met Catherine more than fifteen years ago, when we were looking for our first yacht. She was the most professional, effective and technically comprehensive salesperson we encountered, yet with an absolutely charming and friendly attitude and personal approach. We never regretted our choice, everything that was promised, was there, and much more. And many years after, we are coming back to her with pleasure. She is a true expert in multihull fleet, and manages to find and complete the best deals for both sellers and buyers, with Catherine's unique diplomatic and professional style. Keep up your great work and thanks a lot for everything!
Mikhail and family.

Hello Mrs Relandeau

I have decided some time ago to sell my boat, a catamaran LAGOON 630 POWER of 2017.
I would like to express to you my full satisfaction at the follow-up and completion of this sale, which took place with several brokers, one of whom was of the same nationality as the buyer, namely Italian. You were a key player in this sale and listened to all my expectations. This, in the context of a case complicated by the presence of an LOA that had to be cancelled by the purchase of the boat by myself.
Your sense of listening and your perfect knowledge in the field of sales have allowed me to end up in very good conditions.
You have always respected your deadlines and commitments.
That is why I wanted to extend my congratulations and thanks for your perfect cooperation.
Yours truly

Jean-Pierre ANDREIS

Hello Catherine,
I especially want to thank you for your efficiency.
We have used your services twice for the sale of our catamarans. You have shown a great deal of professionalism and availability. It was a real pleasure to call on you.

Thank you for your help. Thanks to you the aquisition of my catamaran was a pleasure. So far from the image I had of such a transaction. You knew how to be at my side at every moment of the aquisition (due dilligence, negociation, etc.) by helping me with conpetence and reactivity. You then ensured the service after sales with professionalism by helping me recruit the crew. I’ve never been happier stirring up a broker! the word broker seems to me not very appropriate for the service that you provide so much your services go beyond the simple relationship of a seller and a buyer.

Frédéric and his little family ...

Thank you once again for your effort, your help and your professionalism!

we are really happy we had the chance to meet and cooperate with you. 

You are a really wonderful person.

Hope we will have the opportunity to meet again very soon.

(Maybe for sailing in Greek Islands :)

We bought a Privilege 465 Catamaran in the spring of 2019, Catherine Relandeau was the agent on our purchase. We felt very secure doing this, and feeling secure is a key factor when you as a buyer are dealing abroad. Catherine was always quick to respond and found multiple solutions on occasions where there was a bump on the road, her firm experience, good reputation and a lifetime of knowledge, on multihulls made us always make sure that we where in the right hands. Even after we have purchased the boat Catherine is still helping us with questions and answers. We are very happy with our purchase and we are now one step closer to reach out dreams. Thank you for the support and professional handling of the dealing and the purchase. I can clearly state that we will always be a longterm customer to Cathyacht and Catherine.

I contacted Catherine at the risk of searching the internet in the obtic to find a catamaran adapted to our desires and our needs (family and living on board). Falling on Catherine was easy, she was always very professional, available and above all very intuitive. She does what is necessary to ensure that the handover is as good as possible for both parties and demonstrates altruism. 
We are now in Polynesia on our boat, also thanks to it.
We therefore recommend it without reservation.



“The assistance of Mrs. Relandau and CathYacht was instrumental in facilitating the painstaking process of fitting out and delivering of our first private yacht. We recommend them both without hesitation to any first-time and seasoned yacht lovers.”


Mauro Gestri


"Having worked in the Catamaran business for many years I have observed both sides of the industry, brokers who truly care for and serve their clients, and those who don’t. Catherine’s vision and ethics are truly client driven. She is willing to go the extra mile for her clients. We have completed several luxury brokerage transactions together such as Privilege 615's, and 745's, etc.. even custom new build transactions of catamarans over 75'. From my experience of over a hundred catamaran transactions, Catherine has always stood out from other brokers with her knowledge of catamarans and willingness to work together for the best interest of the client."

My first contact with Catherine was at BOOT 2007, when she asked me to be her Privilège dealer for Holland.

Since then we worked together first with Alliaura Marine and was later on invited by her to support the at restart of the Privilège yard in 2008.

I know and respect her the way she is dealing with clients on a charming but very dedicated professional way.

Always focused  and listening to what a client wants but also considering and explaining to the client what could be possible or sometimes not.

As since October 2010 we are also business partners in CATAMARIS where she brings her > 25 years of experience in large luxury multihulls.

It is always a pleasure to work with her and hopefully it will continue for many years in future !



Thank you for your continued back up over the years we have worked together.

It has always been a pleasure and most helpful when we have required information from you especially regarding our Privilege 745.

I wish you the best in the future.

Catherine has already sold me several boats, small, medium and large. It has always gone well and I am very satisfied with his services. It is very introduced in its various networks and this opens many doors to it, thus facilitating contacts with the different actors of the world of boating both in France and abroad.




I have known Catherine Relandeau for over 20 years and during that time have spent many hours dealing with her for the supply of large catamarans. I have found Catherine to have a vast knowledge of the marine industry and is able to fulfil the differing requirements of fastidious owners. Due to her long experience I know Catherine has has some strange  requests from buyers when specifying a new boat which she has generally been able to satisfy them as well understand their needs. When these attributes are coupled with her friendly and approachable manner, not to mention her multilingual skills, she is a pleasure to deal with.

We have known you Catherine for almost two years and thank you warmly for your help, your valuable advice and for all the after-sales follow-up of our Lagoon 630.
It is rare to meet professionals like you with not only considerable experience of the boats but also remarkable insight into the needs according to the personality of the buyers and their navigation project.
Being accompanied when buying a boat is essential but with you, the mandate does not stop there because you have been available for the future and always with benevolence. 
It is a real pleasure to work with you, Catherine, both for your investment and for your human qualities.

I had the opportunity of purchasing a lovely privilege via Catherine.

We did get from her a very profesional care .. buying this boats requieres money transfers and fears are always there.. Catherine clears all this  fear away... Tx

Privilege 615



Alice and I have been working with Catherine for two years now. We were looking for a larger catamaran between 55 and 70 feet to explore the world from sea. The search was not easy, because we had certain ideas regarding space, comfort, handling and safety. We were faced with the choice of buying a new Cat or then a well-preserved used Cat. After visiting various boat exhibitions, we quickly realized that a new Cat with our desired ideas was hardly affordable. So we were looking for a used Cat, which was in good condition and affordable. She suggested various ships and, if the interest was there, organized perfect viewing appointments. She was also on site and showed us the ship in detail. Finally we found a Privilège 615, which corresponded largely to our ideas. Catherine recommended a good shipyard with her long-standing and broad knowledge. She also accompanied us to the first discussions with the shipyard and supported us very much in the discussions. Catherine handled all formalities with the seller and the foreign authorities with dedication, absolutely professional and to our complete satisfaction. We will stay in touch with her in the future and can highly recommend Catherine as a yacht broker.  

Alice und ich arbeiten nun seit 2 Jahren mit Catherine zusammen. Wir suchten einen grösseren Catamaran zwischen 55 und 70 Fuss, um damit die Welt von See her zu erkunden. Die Suche war nicht einfach, denn wir hatten gewisse Vorstellungen bezüglich Platzangebot, Komfort, Handling und Sicherheit. Wir standen vor der Auswahl einen neuen Cat oder dann einen gut erhaltenen gebrauchten Cat zu kaufen. Nach dem Besuch diverser Bootsausstellungen erkannten wir schnell, dass ein neuer Cat mit unseren Wunschvorstellungen kaum bezahlbar war. Also suchten wir einen gebrauchten Cat, welcher in gutem Zustand und preislich tragbar war. Bei dieser Suche war uns Catherine sehr hilfreich. Sie schlug uns verschiedene Schiffe vor und organisierte, wenn das Interesse da war, perfekte Besichtigungstermine. Sie selbst war jeweils auch vor Ort und zeigte uns das entsprechende Schiff im Detail. Schlussendlich fanden wir eine Privilège 615, welche unseren Vorstellungen grösstenteils entsprach. Gewisse Dinge sollten aber noch überarbeitet bzw. ergänzt werden. Da hat uns Catherine mit Ihren langjährigen und breiten Kenntnissen eine gute Werft empfohlen. Sie begleitete uns auch zu den ersten Gesprächen mit der Werft und unterstützte uns sehr bei den Diskussionen. Der Kauf der Yacht inkl. aller Formalitäten mit dem Verkäufer und den ausländischen Behörden wickelte Catherine engagiert, absolut professionell und zu unserer vollsten Zufriedenheit ab. Wir werden auch zukünftig mit Ihr in Kontakt bleiben und können Catherine als Yacht-Brokerin wärmstens empfehlen.  


Rolf & Alice, Baar,



I would like to salute the commitment of Catherine who goes so far as to cross the planet to show my boat, a privilege 515, to the Tuamotu on a small island "End of the world (Apataki)»

“I first met Catherine at the Miami Boat Show a couple years ago and she introduced me to the amazing Privilege catamarans.  Now I own a 62’ Privilege! Even 2 years later she is always there when I need help, giving me advice and connecting me with her deep network in the catamaran world. You will be happy you chose to work with Catherine.”

I am looking forward to the next sales.....
Best regards

We have nothing but fond memories of working with you at Alliaura on P435 #5 the Gato Chateau.  Our perception was that you were our ally in working through the yacht design, build and purchase process.  We found you to be honest, and most importantly trustworthy. As an added benefit, when we ran into you at the Miami show last year, we felt we indeed had rediscovered a long term friend!

Catherine, your experience and expertise were critical in the building of Captiva (Privilege 745). Your willingness to help with every little detail after the build completed, was a true testament to your dedication. 

Thank you 


Dustin Graham



I believe that we have known each other since the acquisition of a Privilege 495 for more than ten years.
I think the seniority of this relationship allows me an authoritative and objective opinion.
For me the most important thing in the seller/buyer relationship is advice and advice in the long term.
At the shows, you come across a lot of sales people, but few really care about your problem. 
In fact, listening to them, everything is simple, possible and there will never be a problem.
But where will they be when Monsieur problème arrives?
In fact, no one sells you a boat, you buy it most often on a more or less reasoned or reasonable liking

On the other hand, it is necessary to find a real advice for the choice of equipment and therefore the adaptation of the boat to the sailor that you are.
That’s where a lot of the sales people are failing, either because they’re not very qualified or because they’re good sailors. And often, they make the mistake of judging your needs by their skills. 
To sum up my thoughts on your skills:
“Great listening skills, appropriate advice, and most important to me: honesty and loyalty.”  
And because you’re your own employer, you’re not here to do a job, you’re here to last. 


J.L Macaud




Dear Catherine ,

As usual its always pleasure to contact you regarding catamarans ,your knowledge and experience well aprecieted   !

Golan Levi



We’ve known Catherine for over 25 years. 
Since we are interested in sailing with catamarans, our first charter experience, our first 10 meter long Lerouge design, up to our decision to acquire a 50 foot privilege, our catamaran sailing life has accompanied you.
In this fast-paced industry, such consistency is absolutely unusual and remarkable.
We appreciate your huge industry know-how, your own experience in yachting and your network that has grown over the years. There is no new development and no change in the market that she does not know and about which we like to talk shop with her again and again
Their friendly and warm manner is the key to their success, which is confirmed by all the other customers we know."


„Wir kennen Catherine nun seit über 25 Jahren. 

Seitdem wir uns für das Segeln mit Catamaranen interessieren, unseren ersten Chartererfahrungen, unserem ersten 10 Meter langen Lerouge Design, bis hin zu unserer Entscheidung, eine 50-Fuß Privilege zu erwerben, begleitet Sie unser catamaran-seglerisches Leben.

In dieser schnelllebigen Branche ist solch eine Konstanz absolut ungewöhnlich und bemerkenswert.

Dabei schätzen wir Ihr riesengroßes Branchen-Know-how, ihre eigene Erfahrung im Yachting, und ihr über die Jahre gewachsenes Netzwerk. Es gibt keine Neuentwicklung und keine Veränderung am Markt, die sie nicht kennt, und über die wir immer wieder gerne mit ihr fachsimpeln.

Ihre freundliche und herzliche Art ist dabei der Schlüssel ihres Erfolges, was auch alle anderen Kunden, die wir kennen, bestätigen.“


Wolfgang Höffken



Miss Catherine Relandeau is one of the few brokers that knows her product well and she is very focused and extremely in tune with the needs of her clients no matter how difficult they maybe be. In my few years working with her, she has been a tremendous help in the knowledge of her boats and yachts and her kind and patient manner with clients. She helped me immensely to gain knowledge of catamaran boats and yachts, it was a great pleasure in working with her. Thank you Catherine.

"I have had the privilege and the pleasure of working with Catherine on several brokerage deals.

The first time, we collaborated on a new Privilege S6 (the hull #1) and the second one was on Cartouche (the 2010 Blue Coast 95’).

 She is an experienced broker with a deep knowledge of multihulls.

Catherine tirelessly represented her clients with integrity and passion. 

She is an asset in any transaction because of her experiences and her aptitude on specific issues involving international transactions. Moreover, she is fluent in French,

​Jean Marie Cabri, Broker




I have worked with Catherine Relandeau for over 15 years.  In particularly, I worked with her quite closely when Alliaura marine (Privilege) built my Privilege 585 in 2002-2003.


Her dedication to quality and customer satisfaction is superb – and her technical and practical knowledge of catamarans, both sail and power, is unmatched.  Catherine is one of the world’s most informed and talented people in the areas of catamaran construction, sales, resources and service. 


After Catherine left Alliaura / Privilege to form her own boat brokerage house, I watched with pleasure as she built CathYacht into the premier international brokerage firm focusing on catamarans.  When people seeking to buy or sell a larger cruising catamaran ask who they should turn to, everyone’s first answer is: Catherine Relandeau at CathYacht. 


I could not agree more. 


Joshua Goldberg, Owner



Catherine RELANDEAU knows her job, she does it well! We were able to appreciate his qualities during the sale of our Privilege 495 in December 2016 in the Caribbean. She did not hesitate to travel several times to help us meet American clients. It is in experienced sales that she led these meetings, we formed a friendly team united as if we knew each other since always, serious, joyful, efficient, professional, with this touch of elegance in the spirit of PRIVILEGE!


Danielle et Michel




Hello Catherine,

We were delighted with the result of the two missions we had entrusted to you, on the one hand to sell our catamaran Jean Baptiste 1er, PRIVILEGE 48 built in 1992, and then to acquire a PRIVILEGE 585. This allowed us to buy TAHUATA, a magnificent catamaran of almost 18 meters.
In both cases, we appreciated your professionalism and the transparency you demonstrated during these two operations. After these two experiences, we were not disappointed in our operations, and I am sure we will continue to work together.
Very kind of you!





“a true professional who offers offers that meet our needs and who has been able to analyze them well…. And friendly as well.



I was fortunate to have workd with Catherine Relandeau during the new build of a Privilege 745 that was named MATAU. She stands out in the industry with her exceptional product knowledge and her professionalism. The entire experience of working together was certainly enjoyable and as a result the client received delivery of a significant superior catamaran. I look forward to working again in the future with Catherine and wish her the best of luck with CathYacht.


Darrell Hall

Founding Partner



We have known Catherine Relandeau since before we purchased our very first Catamaran, back in 2007.  Since then, she has assisted in presenting us various Catamarans, that we have been looking to purchase, and in the selling of our own.  She always takes great care and personal interest in both her buyers and sellers, in the most professional manner.  


Melissa & Francesco Candiani

Ombre Blu



Catherine Relandeau represented the seller for a boat that I purchased.  I found her to be outstanding in every way, a consummate professional. She worked tirelessly to close the deal on my schedule, working through holidays and taking whatever measure were required to complete the deal.  She was able to effectively deal with selling a French registered boat to a US entity with complete aplomb.  I couldn't recommend her more highly.  When the time comes for me to sell and/or buy my boat or another, I will ask Catherine to represent me.


Glen E Doyon, DMD



Dear Catherine,
It can’t be true that you won’t be working for Privilege Marine in the future! What would Privilege Marine be without you?! Now that we have known each other for more than 13 years and I have met you as a competent and charming contact person at Privilege Marine, I am extremely sorry that you are ending your work there. I wish you and your company Cathyacht much success and I am sure that our paths cross again and again and then I look forward to seeing you again!
Thank's again and best wishes

​Liebe Catherine,


das kann doch nicht wahr sein, dass Sie in Zukunft nicht mehr für Privilege Marine arbeiten! Was wäre denn Privilege Marine ohne Sie?! Nachdem wir uns nun mehr als 13 Jahre kennen und ich Sie als ebenso kompetente wie charmante Ansprechpartnerin bei Privilege Marine kennengelernt habe, bedauere ich es außerordentlich, dass Sie Ihre Tätigkeit dort beenden. Ich wünsche Ihnen und Ihrer Firma Cathyacht viel Erfolg und bin mir sicher, dass unsere Wege sich dann und wann wieder kreuzen und dann freue ich mich auf ein Wiedersehen mit Ihnen!

Alles Gute und herzliche Grüße

Ihr Wolfgang Boorberg



“Having decided to buy a Privilege 615, I quickly established that Catherine Relandeau was the perfect agent to help me find the best boat and the best deal.


Catherine has an in-depth knowledge of the Privilege yachts and was able to guide me through each boat that was on the market at the time. If ever the time comes that I wish to sell my Privilege 615, Catherine Relandeau will be the first person I will be calling”
