Physics
What physics keeps rowers balanced at the end of each stroke?
Quick fact
The lean transfers the rower's body weight to balance the boat's longitudinal pitch, keeping the hull level and reducing hydrodynamic drag by up to 2%.
Why this is interesting
Rowers lean back not to rest their backs, but to prevent the boat from 'kicking' up at the bow—a motion that can cost them half a second per stroke.
