Notes: Starting from the left of the graph: the angle decreases during the recovery, reaches a minimum as the rower gets to frontstops, then increases as the rower drives. During the drive, the force reaches a peak, then tails off. The force is released completely as the angle reaches a maximum (i.e. at backstops). The recovery cycle then recommences.

The black vertical cursor line has been placed over the peak force, which is shown to be 106.3kgf occurring at -19.7°. Zero degrees is when the oar is at right angles to the hull, so -19.7° is in front of the mainstay.

In this example, the rower shows a good smooth action and a well developed force curve.

Notice that the force starts to increase slightly before the blade is put in the water. This is due to the hull decelerating - i.e. the pin pushes back onto the oar, which creates a "positive" force.
