Why standard blades need pitch and RANDALLfoils don’t?

Standard blades require pitch to create stability during the drive phase of the stroke. Without pitch on the blade the rower has very little control over its depth and can wash-out or deep dive.

Blade pitch, however, reduces the efficiency of the blade as a total horizontal force. Instead of the rowers’ energy being translated into horizontal boat speed, some is transferred downward.

While blade pitch makes taking powerful strokes with conventional blades possible, ‘elite’ crews try to find that sweet spot between crew stability and maximizing blade efficiency, always trying to reduce pitch as much as possible.

With RANDALLfoils, blade pitch can be minimised (some users report 1-degree) without the loss of any stability, but gaining total horizontal blade efficiency. All of the rowers’ power is transferred into direct horizontal motion.
