They never saw a hull form with small steps in it either....

The theory is that the eddies create [revent the formation of drag and thus increase efficiency.
The degradation of eddies in slurries containing small quanitites of sand have been reported as reducing the friction at the boundary resulting in lower pressure drops. See work by Wilson Addie Clift & Thomas.
Uneven surfaces n the pipe wall is the reverse of this one could suppose.
