WSV Achter 't Veer is a volunteer-run marina with 145 moorings situated in the center of Geldermalsen on the Linge — described as the longest and most scenic river in the Netherlands — in the heart of the Betuwe region.

The harbor has been active since 1961 and includes winter storage, a transient harbor, 16 camper pitches, a trailer ramp, modern sanitary facilities, and an energy-neutral harbor building called 'Het Veerhuys.'

The marina sits directly alongside the town, putting supermarkets, shops, restaurants, and the market square within easy walking distance. A train station is about fifteen minutes on foot.

Twenty berths are reserved for visiting boaters, and the harbor master assists with mooring upon arrival. The location makes a practical base for exploring the broader river area by boat, bicycle, or on foot.
