WSV De Maas is a well-maintained marina and watersports club located on the Maas, roughly 3 km north of the centre of Venlo in the Dutch province of Limburg.

Founded in 1931, the club serves over 300 members and accommodates motorboaters, sailors, rowers, and sloep rowers. The main marina offers 200 permanent berths, while a separate city harbour in central Venlo provides 30 visitor berths.

The site also functions as an access point along the Maas, with a fuel station on site. Complimentary loan bicycles are available, making it easy to explore the surrounding area, including the nearby villages of Blerick and Grubbenvorst.

Reservations for visitors and campers are not accepted; check-in is handled directly with the harbourmaster.
