WSV Treech 42 is a boat ramp associated with Watersportclub Treech '42, a long-established water sports club situated on the banks of the Maas in the Sint Pieter district of Maastricht.

The slipway serves as a small-craft facility, providing access to the river for club members and visitors launching non-motorized and motorized watercraft. The club itself was founded in 1942 by canoeists who chose this quiet stretch of the Maas as their base.

Over the decades it has grown into a well-known multi-sport venue, with the marina and slipway forming a central part of its waterside facilities alongside a swimming pool, playground, sports fields, and jeu de boules courts.
