In addition to a slimmer profile of oar from end-to-end the smaller elliptical shaft has better aerodynamic features. The faster the boat the great the potential benefit. New shaft construction ensure the same stiffness as the “Classic” sweep version, with an overall oar weight is quite a bit lighter at the same rig.


Relative Drag of Various Shapes of the same frontal area727x600_300RThe slim “Ellipse” has significantly less drag than that of a circular shape of the same profile thickness.






An additional feature is the tool adjustment feature that allows easy on-the-water adjustment of sweeps as wind conditions change. This feature has be in use for two years on the Dreher Alpha Sculls and then on all Dreher Adjustable Sculls. When used routinely, this feature will be a great competitive advantage.
