Abstract
An oarlock (26) for a rowing shell (42) is threaded onto an adjusting tube (10) longer than the oarlock and just shorter than an oarlock pin (16). This oarlock/tube assembly is slipped over the pin and secured so that it is free to pivot. The pin is attached to a sill (28) of a rigger (32). Manual turning of the tube will raise or lower the oarlock without disassembly to make adjustment for height and weight of rowers or changing water conditions.
