With our ships we offer trips in collaboration with the foundation The Ocean Movement.

The Ocean Movement (formerly By The Ocean We Unite) is a Dutch foundation with charity status (ANBI) that wants to prevent plastic from ending up in our oceans. They do research, educate and activate people, organizations and governments by organizing a variety of activities - sailing expeditions, lectures, documentaries. Read below about the mission and research that The Ocean Movement does, and how you can expand your sailing trip with a plastic component, a fully catered corporate expedition or join one of the plastic soup expeditions.

The mission of The Ocean Movement is to take people (in real life or digitally) to our oceans and seas and make them aware of the plastic soup that has turned our waters into. Through scientific research, we want to increase knowledge about the causes and consequences of plastic pollution at sea. To really prevent plastic from being thrown away in nature, we give people tips to change their own behavior. To increase the positive impact, The Ocean Movement joins forces with many individuals and organizations worldwide.


Plastic pollution has become one of the greatest environmental challenges of our time. On average, eight billion kilos of plastic end up in our oceans every year, that's 23,000 kilos per minute(!). The Ocean Movement believes that together we can tackle this problem. We need to share knowledge and inspire change. Focus on what we can do and tackle the problem at the source!


The Ocean Movement believes that seeing is believing. That’s why we take people on a journey to show them that there are tiny, polluting bits of plastic everywhere. By taking samples, The Ocean Movement researchers can show expedition members fragments that are invisible from above. In this way, we show how much bigger the problem is than just the larger bottles and bags floating around.



Citizen Science


With their Manta Trawl, researchers from The Ocean Movement collect samples to search for plastic particles in the surface water. The Manta consists of two metal wings that float on the water surface and has a wide mouth. The net behind the system skims over the surface and catches everything in the top layer. The design is based on the manta ray, a large ray species that mainly feeds on plankton by swimming with its mouth wide open.

The Manta Trawl does essentially the same thing; it filters the top 15 cm of the water column with a net with a mesh size of 300 micrometers (0.3 millimeters) and collects the plastic particles in the end of the net, also called the cod end. The trawl is towed by a vessel for 30 minutes at a speed of up to 3 knots, according to a standardized protocol designed by the 5Gyres Institute. Then the plastic particles caught in the cod end are collected, sorted and measured. Finally, the concentration of plastic particles in the water is calculated from the items found per trawl and the amount of water filtered during towing is measured with a flow meter.

With the expeditions, The Ocean Movement shows passengers the beauty of the water and at the same time confronts them directly with the plastic waste that threatens them through (citizen) scientific research.




The dedicated marine biologists and expedition leaders have years of experience in leading research programs and expeditions on board various sailing vessels. The team with strong communication skills consists of professionals and is able to serve any audience.


At sea, clouded minds are cleared and hearts begin to beat faster again with excitement about our beautiful planet. And the need to protect it.


Don't wait any longer – the time to tackle the plastic problem is now!

The possibilities

Want to increase the positive impact of your sailing trip? Add a plastic component to your onboard program. For example, you can go out with a marine biologist from The Ocean Movement to conduct your own research with the Manta Trawl. Are you interested and want to know more?

Looking for a unique one, two, three (or more!) day corporate sailing expedition where you jointly contribute to the protection of our oceans from plastic pollution, create new connections and enjoy being on the water? We arrange this for you!

Our experienced crew, caterers and the expedition leaders and marine biologists of The Ocean Movement are ready for you!

Get to know each other, the beautiful nature that the Netherlands has to offer and the challenge of plastic pollution a little better. Help The Ocean Movement collect scientific data and learn more about the power of individuals. Or the possibilities for your organization. Click here for more information.


Would you like to join one of The Ocean Movement Plastic-soup Expeditions alone or with a smaller group? An adventurous and unique sailing expedition on the UNESCO World Heritage Wadden Sea! Learn all about sailing and plastic pollution while being on the water. The professional crew will make sure you have a great day!
