About our management team

“It is a beautiful thing when career and passion come together”

Christian M. Poorte

Managing Director, Naval Architect, Bachelor in Engineering

Born and raised on the Frisian lakefront, Christian’s passion for sailing and ship’s carpentry evolved quickly to a vocation in naval architecture and design after his apprenticeship at Royal Huisman in 1989.

Leaving university with a degree in Naval Architecture, he gathered a versatile experience in marine engineering and project development which resulted in many well-recognized and award-winning yachts.

At Royal Huisman he has fulfilled management positions in Project Management, Design & Engineering, Business Development and Contract management. Before his appointment at Royal Huisman in 2010, Christian was a Co-owner, Chief Naval Architect and Director of Engineering at Vripack. He was involved in numerous projects,  developed and built worldwide.

In 2017 he decided to concentrate on his strength in engineering & project management and thus, Arcadia Maritime Group came to life.

Christian is member of the Royal Institute of Naval Architects (RINA) and The Institute of Marine Engineering, Science and Technology (IMarEST).

Donka G. Poorte-Efremova

Project & Office Administrator, Master of Arts

Donka has taken a keen interest in languages and travelling since childhood. This aspiration of hers predestined her course of education and job preferences.

After graduating the English Language School in her hometown Rousse (Bulgaria), she got a Master Degree in Arts (English & Bulgarian) from University of Shumen.

Having worked as a teacher in English for several years, she took the challenge to immerse as an office administrator in a multinational environment in Rousse Winery JSC. At that period she could perfectly combine her two passions – languages and travelling.

When the winery got sold, she went back to the teaching endeavour again till 2006. This same year she joined the Bulgarian office of Vripack, where she got her basics in yacht engineering and project management. It is also where she met Christian, who later became her partner in life and business.

She has a good command of several foreign languages (English, Spanish, Russian, Dutch), among which English takes the lead.

Powering Sustainability

The use of energy is growing rapidly and the resources of our planet are already under great pressure. We need to change the way we produce our energy. We need to produce more renewable energy, and the most promising source of energy is the power of wind.


Energy is to be an important catalyst for founding a better quality of life. A stable energy supply is an essential part of the infrastructure for a developed society. Energy is central to nearly every major challenge and opportunity the world faces today. Be it jobs, security, climate change or food production – access to sustainable energy is essential for strengthening economies, protecting ecosystems, reducing poverty and achieving equity.

The world we live in is the one we create ourselves, by our thoughts and actions. It is therefore that the Arcadia Maritime Group is investing in a sustainable future.

By its participation in sustainable equity funds Arcadia Maritime Group invests in Vestas, the world’s largest producer of wind turbines and renewable energy hybrid solutions. Vestas actively supports partnerships and collaborative efforts intended to advance the sustainability agenda.

Through harnessing the power of the wind, Vestas 11th Hour Racing supports Vestas’ goals and is a unique platform to promote Vestas’ vision to be the global leader in sustainable energy solutions. “The Volvo Ocean Race is a proven platform for Vestas and a unique strategic fit to promote our new vision and market-leading energy solutions in our key markets while engaging with customers,” said Vestas President and CEO, Anders Runevad.

“Furthermore, our partnership with 11th Hour Racing sends a very strong signal on climate change as two leading players within sustainability combine forces to promote sustainable solutions within wind and water”.

11th Hour Racing Co-Founder, Wendy Schmidt, who is also President of The Schmidt Family Foundation, says: “sailors are the most natural advocates for the health of our oceans and waterways. Our partnership with Vestas is about inspiring positive change in the way we think about energy and the natural resources of the planet”.

“As co-title sponsors of this team, we will engage fans in increasing understanding about our vital connection to the oceans and showcase how embedding sustainability in a top level professional sports team can drive performance, efficiency and innovation. Our work has shown us this is a winning strategy.”


Where we are


Our Office

The office of Arcadia Maritime Group is located in Zwolle, The Netherlands. A beautiful town with a great maritime history. Zwolle had been a member of the Hanseactic League since 1294. The Hanseatic towns of Eastern Netherlands were powerful and impressive at that time. The Hanseatic League was a union between cities which sought to support each other. The cities’ wealth was reflected in their commanding new structures, elegant merchant houses and impressive buildings. Their wealth also resulted in the Golden age of arts (among other things). In a way, the medieval Hanseatic towns had their Golden Age before the rest of the country did. Fortunately for us, it left many traces in Zwolle…
