WSV de Snap is a watersports association based in Hardinxveld-Giessendam that operates two harbour locations.

Its Het Balkengat harbour sits on the Buiten-Giessen and can be reached via the Damsluis when approaching from the Alblasserwaard, or via the Peulensluis on the northern bank of the Beneden-Merwede.

The association's second harbour, De Knaal, lies at the start of the Kanaal van Steenenhoek and is accessible from Gorinchem via the Lingehaven, the Linge, the Merwedekanaal, or the Kolffgemaalsluis.

Het Balkengat is situated close to the centre of the municipality, making it a convenient stop for day trips or provisioning. The harbour accommodates vessels under 10 metres and between 10 and 20 metres, with both side-to and stern-to berthing on fixed docks.

Tidal flow is negligible, and the marina remains active in winter.
