WSV De Put is a recreational marina located on the northern shore of the Haringvliet, near the village of Goudswaard in Zuid-Holland.

The harbor has its origins as a clay pit excavated for dike repairs following the 1953 flood disaster, and was gradually transformed into a marina during the 1970s and 1980s. The watersportvereniging (sailing club) was formally established in March 1978.

The marina sits directly opposite the island of Tiengemeten and borders the natural area known as the Tiendgorzen, offering sweeping views across the Haringvliet.

With around 250 permanent berths, the harbor also welcomes visiting boaters, who can moor at the guest pontoon on the north side of the basin. The entrance is marked by two small yellow buoys.

The Putdijk alongside the harbor is a pleasant spot to relax, lined with characteristic pollard willows and overlooking the water.
