2027
Blauwe Long (Blue Lung)
About 50 boats of sailors who are out a lot, one full season on the North Sea coast, Wadden Sea, IJsselmeer, Markermeer and Zeeland. The first real fleet. We're looking for funding.
Expeditions
Expedition 2026
Our first voyage at sea: from the IJsselmeer through the Kiel Canal to the Stockholm archipelago and back to Belgium, summer 2026.
Aboard a new Contest 63CS, made possible by the Naiad Foundation.
The voyage
In June 2026 we installed both tiers on a new Contest 63CS and let it sail a real summer: seven weeks under way, no one from the project on board.
It showed what works (air pressure, depth, water temperature) and what doesn't yet (water-chemistry sensors that last, wind under sail). That's exactly what we needed to learn before building a fleet.
The full results are in our paper for IEEE MetroSea 2026. Read the abstract
Where we are
Short version: the idea works at sea. Now it needs more boats.
Air pressure
Ready
Weather-station quality.
Depth and water temperature
Ready
Usable, especially in shallow coastal water.
Water quality
In development
Salinity and pH pick up real gradients; the probes don't yet last at sea, and oxygen isn't there yet.
Wind
In development
Collected, but not yet good enough under sail.

Thanks
Thank you to the Naiad Foundation and Contest Yachts for hosting the expedition and supporting the installation, to Aknostic for the data platform, to PredictWind for partnership, and to our skipper and volunteers.
What's next
More expeditions are planned for 2027.
2028
Mediterranean charter fleets
Nodes on charter boats in Croatia, Greece and Turkey, planned with Velamari as part of its fleet service, with the data shared with SeaSense.
2027+
More expeditions, wider waters
More voyages and hosts beyond the Netherlands, so each new region starts with boats already signed up.
