Jachthaven De Brasem is a small, welcoming marina situated directly on the Braassemermeer in Oude Wetering, Zuid-Holland. It offers permanent moorings for around a hundred boats, accommodated in a covered shed, in boxes, or along a long dock.

Visiting boaters are well catered for, with dedicated guest pontoons featuring built-in wave breakers that shelter vessels from chop, along with fine views across the Braassemermeer. The marina lies favorably along the staande mastroute.

Facilities include toilets, showers, a laundry room, and free Wi-Fi throughout the harbor. A restaurant is on site, and a supermarket, bakery, and other shops are within a few minutes' walk. The harbormaster can be reached on VHF channel 31.
