This is a new generation of slim, The Dreher Slim Ellipse Sweep Oar. These oars are available in:
- Two levels of Stiffness: Less-Stiff (5.5 cm deflection) and Standard Stiffness (4 cm deflection).
- Two grip types: Row-Wik over carbon and Heatshrink over Carbon
- Two grip Colors: Black (Row-Wik) with outboard slightly textured carbon or Heatshrink: Red or Black over Carbon
- Oar Length / Inboard (+/- cm): 371/114, 374/114 or Call
- Tool Free Adjustment Type (TFA): Premium Sleeve/Collar Material (Carbon / Nylon)
- Blade Type: Apex-E.
- Includes Locking Lack
- Optional: Tool Free Onboard Wrench for Total Length Adjustment (will receive a 10 mm open-end/box wrench instead)
Since the shaft starts as a circular sculling shaft size for about the first 1/3 and transits to a slim ellipse through the remainder of the shaft and as such the blade shape selected is the popular Apex, but modified to fit on an elliptical shaft (i.e., Apex-E). The new oar has one type of tool-free adjustment materials: Made of a premium material. TFA inboard/outboard assemblies come in a black bearing surface (movable sleeve/collar) with a red adjustment nut and couple. This sleeves/collar assembly travels on a segmented screw 1 cm with for every 360 degrees rotation of the red adjustment-nut with a nut locking clip.
Because a greater percentage of high modulus carbon versus unidirectional carbon prepreg is used to achieve the same levels of stiffness as the classic larger dimension sweep oars, we get a lighter overall sweep oar (with standard stiffness shaft the weight savings under 1 pound per oar) and the superior aerodynamics of the elliptical sweep shaft and streamlined blade and blade shaft interface, this design will provide superior performance especially the faster the boat and the greater the headwind.
The Tool-Free Onboard Wrench is optional with sweep oars.
