RV Adriaen Coenen
RV Adriaen Coenen is an 19m-long inland vessel mainly used for a day-long expeditions, short sampling trips, such as student activities and transporting scientists and samples since summer of 2022. The main operational area is the Wadden Sea, such as the Balgzand and the bird observatory on the island of Griend. The design with 1m draft and aluminum hull allows her to pass the slack waters at low tide and settle on the mudflats when tide recedes.
RV Adriaen Coenen comes with an A-frame, side cranes for small-size scientific instrument and deck space for a RIB. These features help support the marine research community and monitoring efforts of the Wadden sea and the Dutch inland waters.

Construction
In March 2021 the NWO-I Foundation Board approved the NIOZ investment for the construction of the second new ship in the national research fleet. The seriously outdated support vessel RV Stern was in urgent need of replacement. Next Generation Shipyards in Lauwersoog won the tender to build the RV Adriaen Coenen. She was christened on 6 July 2022 and sailed to Texel in August 2022 to start her work on the Wadden Sea.

Name
The new vessel was named after Adriaen Coenen (1514-1587), a fishmonger from Scheveningen. He was a fish auction master and an amateur ichthyologist with a passion for everything living in the sea. Coenen’s ‘Visboeck’ is a remarkable publication. The 16th-century manuscript is richly decorated with colour illustrations that provide researchers with useful knowledge about 16th-century fisheries.
