Description

The Dreher Apex Sweep oar is one of the most successful sweep designs produced to date. The Apex55 Blade Shape was introduced at the 1999 Head-of-the-Charles Regatta. This was our “Next Generation” of blade shapes for both sweep and sculling. These blades have both a smooth front surface, and most importantly, a smooth back surface to provide better hydrodynamic lift. The Apex52 sweep blade was introduced in December of 2010. This is simply a 55 cm blade length shortened by 3 cm.p blades. The results of the testing were so favorable that we decided to start selling the new blade shape world wide in January of 2011. The Apex blade shape became a significant design improvement. What we did was move the attachment spine to the top of the blade (the “apex”) on both the front and back parallel to the direction of water flow as the blade traverses out and back from the boat. The spine was changed to a smooth contour and the volume calculated to effect a displacement enough to give the correct buoyancy as well as the right weight and weight distribution, which affects the balance point. In addition, the blade is made to the FISA minimum thickness of blades (i.e., of 3 mm thick blade; 2 mm in from the tip) with a rounded edge to increase efficient blade work.
