No oarlocks, thole pins (sticks of wood) are used instead. The rope that holds the oar to the thole pin goes around the side of the thole pin facing away from the rower.

The black piece on the oar is a length of plastic pipe for chafe protection. The white on the black is just some spilled paint.

The blades of the oars tend to be bolted to the shaft of the oars with a couple of stainless steel bolts.
