Popis:	We describe a method for sampling invertebrate drift from a small boat, using a beam to which conventional drift samplers are attached; the beam is mounted on the oarlocks. This method permits sampling-unit replication and enables the collection of drift from the upper strata of water in large rivers in areas that might be inaccessible to conventional methods.
