Nova Portus is a watersportvereniging (sailing club) and marina located in Nieuwpoort, on the Lek. Visiting boaters are welcome, though all arrivals must first check in with the harbourmaster by phone.

The marina offers a limited number of berths for vessels up to 13 metres in length. Electricity and water are available on the pontoons, and a sanitary unit is on site.

Mariners should be aware that strong currents can develop at the harbour entrance when vessels pass on the Lek.
