WSV Goudswaard is a marina situated on Het Sandee, a former creek and side waterway connected to the tidal river het Spui, just outside the village of Goudswaard on the island of Hoeksche Waard in the province of Zuid-Holland.

The harbor lies in a quiet, rural setting roughly opposite the working harbor of Simonshaven near Zuidland. The marina consists of a long harbor canal and a small harbor basin with a depth of 1. 20 meters, offering 68 permanent berths and 15 visitor berths.

Boaters should be aware that crosscurrents in het Spui can reach up to 3. 5 km/h.

From here, sailors can head north toward the Oude Maas and destinations such as Nieuw-Beijerland and Rotterdam, or travel south toward the Haringvliet, Sommelsdijk, and Hellevoetsluis.
