WSV Den Osse

WSV Den Osse sits on Lake Grevelingen, a sheltered saltwater lake that makes for calm, reliable sailing conditions you won't find on the open North Sea. With 500 berths and Blue Flag certification, the marina keeps high standards for safety and facilities. Come summer, it has a genuine family-holiday feel — there's a beach with barbecue spots and a kids' program running through the season, plus a terrace at the main building where you can settle in and watch the boats.
