Sculling Blade Geometry

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 eight of the eleven sculling blades that we manufacture:
