When racing sailboats they move everything they can to the center mid point of the boat so it uses less energy going through chop. On a bike the motion is much smaller but motion is wasted energy just the same.
We like crystal smooth water to race on but that comes with no wind. Velodrome track smoothness only comes with going no where, everywhere else there's surface roughness.
