Rowing Blade Path - Bird's-Eye view

In this video, Ken demonstrates with slow motion and annotation how the blade travels through the water when looking from above. 

Many rowers and coaches understand that they need a quick catch and a clean finish, but this video visually shows why.

There is a good chance that this video will change how you think about the relationship between the oar and the water. The blade shape, oar angle, and speed of the boat combine to impact the catch and finish significantly.
