W. S. V. Nova Portus is a small members' watersport club and marina situated on the Lek in Nieuwpoort, one of the smallest fortified towns in the Netherlands. The harbour lies along the riverbank at 't Hoofd and offers a quiet, scenic setting.

Membership is restricted to residents of Nieuwpoort and Langerak, though visiting boaters are welcome.

The surrounding area rewards exploration: nearby beaches line the Lek, and Nieuwpoort itself offers walks along its historic ramparts, a museum in the old town hall, and local dining.

The silver-working town of Schoonhoven is within easy walking distance across the river, and the Alblasserwaard polder landscape is accessible by foot or bicycle from the marina.
