Thanks, Frank. I couldn't really time a shot6 that precisely, so I resorted to several rapid bursts, and this was the one that caught the moment best. A rowing stroke is a very complicated athletic maneuver: Drive The drive is the phase from the catch to the extraction. As soon as the oar blade is placed in the water at the catch, the rower begins to lever the boat past the blade by straightening the legs while the body remains leaned forward and the arms straight. This is called the leg drive. The rower continues pushing with the legs while beginning to apply additional power by opening up his or her back towards the bow of the boat. After the rower completes the leg drive, the rower finishes opening up his or her back towards the bow while at the same time using his or her arms to pull the oar(s) to his chest. This is called the draw. The rower pushes the oar handle down so the oar blade comes out of the water. Just as the oar blade is being removed from the water, the rower rotates the oar handle 90 degrees so that the blade is again parallel to the water. This action is referred to as feathering. At this point the rower is in the same position as the beginning, torso leaning back, hands drawn in to the body, and legs extended. Recovery The recovery follows the drive and returns the oar and the rower from the point of extraction to the catch. Just after the extraction (or finish) with the oar out of the water and the face of the blade parallel to the water (the blades are "feathered"). The rower has legs straight, body leaning back, and arms pulled in so that the oar handle is a few inches from the solar plexus. This is the beginning of what is called the recovery or the slide. The rower extends the arms fully forward (toward the stern) pushing the oar away from his or her body while, at the same time, keeping the oar at a constant height with his or her legs straight, and torso leaning back. The rower leans the body forward to around 30 degrees past vertical, continuing to keep the oar level, not bending the knees and keeping the back straight. This stage of the recovery is sometimes referred to as "body prep". The rower bends the legs, bringing the sliding seat forward (i.e. toward the stern) on its rollers, while the oar remains level. While continuing to slide the seat forward, the rower rotates the oar handle(s), causing the face of the blade to be perpendicular to the water. This is called squaring or rolling up the blade. This, depending on the rower's technique, begins approximately when the oar handle(s) pass over the ankles. When the rower reaches the sternmost point of the slide, the end of the recovery, and the shins are vertical, the blade is quickly and smoothly dropped into the water by a slight lifting of the hands. This is called the catch.
