These new sculling oar designs were announced at the FISA Coaches Conference in Paris, November 6-8. The Dreher Aero is a totally new oar for 2009.
The Dreher Aero is a truly revolutionary oar with every aspect of the design, manufacturing process and even the type of carbon used a radical departure from current oar production methods. The result is the first oar that attempts to overcome speed decreases on the recovery. These are due to air resistance on the oar shaft and blade as they both move in the same direction at maximum boat and oar shaft velocity. The result – a shaft shaped like an aerofoil.
