De Kil is a marina and water sports association located at the southernmost tip of the Eiland van Dordrecht, beside the Moerdijkbruggen, in Dordrecht. The site has a long history tied to the strategic position near the old Willemsdorp–Moerdijk ferry crossing.

With 296 berths, the marina sits at a crossroads of major waterways, offering straightforward access to sailing areas including the Biesbosch, Hollands Diep, Nieuwe Merwede, Amer, and Beneden Merwede, most reachable within an hour.

It serves both members and visiting boaters, and the harbor can be reached on VHF channel 31.
