Blade Geometry and Area Summary

Over the past three decades, we have continued to develop and innovate Dreher Sculling Oars in an effort to maximize performance while simultaneously creating ideal blades shape for the various scullers globally. The following charts and diagrams provide a comparison of the blade areas of the six of the ten sculling blades that we manufacture:


  DreherEA or EAX    816 CM*CM           22.2 CM      49.5 CM
  DreherEH or EHX    780 CM*CM           24.0 CM      51.0 CM
  Dreher Alpha
   787 CM*CM           22.0 CM      46.0 CM
  APEX-R or RX    740 CM*CM             NA        NA
  APEX or APEX-X    818 CM*CM          21.6 CM     43.3 CM
  BB2198    795 CM*CM          21.6 CM     43.3 CM
  Little Big Blade    750 CM*CM          20.1 CM     43.3 CM
