BehneMar was founded over 15 years ago on the simple premise to deliver uncompromising excellence in superyachting. We are your experts, your consultants and your partners. We are your voice of experience and your counsel. We offer you a bespoke, highly personal service that spans the superyacht fleet, from under 100ft to over 100m.

From superyacht purchase and new build to yacht management and charter, our leadership team has, in total, more than 50 years’ experience in the superyacht sector. You have direct access to this and our select network of partners – from designers and naval architects to leading shipyards and beyond.

You need a team who are resilient and relentless in their quest to provide you the right level of service. And we understand that the difference between ordinary and extraordinary is that little extra.

Our values

If you have the right people, you don’t need a lot of people

We regard ourselves as consultants, not just advisors. We are here to support your intention to buy, charter or build, providing our expertise to discreetly manoeuvre incredibly complex situations and protect your interests. 


The Family Office for superyachts

Dr. Rainer Behne


A trained medical doctor, life-long entrepreneur and yacht owner, he is the founder and Chairman of BehneMar. His background, incorporating sectors across real estate, private banking and marine services, offers clients an unequalled and more worldly level of expertise and personal service - unique in yachting. 

His personal experience is the basis on which we assist our clients to this day. It allows us to provide our renowned personal consultancy – and has allowed him to turn his hobby into a business. 

His passion for innovation and technology is echoed in his personal life. From collectors’ cars to advances in health technology, he pursues a lifestyle focused on being active and healthy.

Tim Trenker

Chief Executive Officer

A renowned expert across automotive and powered sports, Tim’s passion for innovative design and technology comes from his time as a FIM Cross Country Rally World Champion. His attention soon evolved from the automotive world to focus on superyachts. 

Tim has been leading specialist projects across the MENA region for over 30 years. Now, having lived in multiple countries and travelled extensively, Tim is using his experience to lead BehneMar’s evolution and growth.

Outside of work, Tim prioritises a healthy and sustainable lifestyle, either unwinding in the dunes or on the waves indulging his passion for outdoor sports.

Caroline Grunewald

Chief Operating Officer

An accomplished senior business management executive Caroline specialises in luxury and high value assets. Having grown up aboard her family’s yachts, Caroline understands implicitly, the emotional connection between clients and their vessels. This experience has been augmented throughout her career in the premium luxury space, leading teams across real estate, interior design, specialist private client events, publishing, luxury goods and of course, yachting.

She returns to yachting to support BehneMar’s growth, while retaining the exceptionally personal service for which it is renowned.

A passionate yogi and mum, Caroline devotes her spare time to her family’s and her personal wellbeing, inherent throughout the BehneMar team.

Florian Vinciguerra

Head Yacht Consultant

Despite being one of the younger members of the BehneMar team, Florian shares the same passion for superyachts. Indeed, following the mantra of a healthy mind in a healthy body, Florian spends as much time in and on the water as possible. His favourite quote “No wave too big” can equally be applied to his approach to work.

Graduating in engineering and business, Florian knew his career would combine his passions for the sea, technology and commerce. 

Gregory Alice

Regional Manager

Gregory was destined for a life in yachting. He achieved his first skipper’s licence at the age of 16, before moving to a yacht consultancy by the time he was 20. With a thirst for knowledge and ardour for his work, Gregory has built his experience delivering yachts across Africa, the Middle East and Mediterranean.  

A quick thinker and doer, Gregory brings more maritime experience to the BehneMar team.

Stella Panagiotidou

Charter Broker

With a deep connection to the sea, ingrained from her Greek heritage, Stella knew that her professional path would be closely intertwined with the maritime world. Stella initially explored, and gathered valuable experience in the shipping industry. However, her true calling lay in yachting, which aligns perfectly with her vibrant personality. Here, she has worked closely with sales and marketing teams further enhancing her skills prior to joining the BehneMar family.

Beyond the sea, she is an active volunteer and maintains a healthy lifestyle and regular training programme.



Sarah’s journey to BehneMar is truly international. After amassing many sea hours sailing between countries, she decided to broaden her business experience in commercial shipping and real estate. This experience founds her return to yachting, to support BehneMar’s German clientele.

Away from work, Sarah feels a deep connection with the ocean, identifying with JFK’s iconic quote, she can be found “…back from whence we came”.  When not on the water, as an avid golfer she can be found reducing her handicap on a well manicured green.
