History and Features of Concept2 Oars PDF Print E-mail
Our design objective, from the start, has been to minimize the energy losses associated with oars.

Since 1977, Dreissigacker Oars have offered durability, low maintenance, component constructions system, and reasonable pricing. We are constantly upgrading our processes, precision, and quality control. At Concept2, we specialize in providing the best performance and the best value in oars for competitive and recreational rowers.

ENERGY LOSSES ASSOCIATED WITH OARSFEATURES OF DREISSIGACKER OARS WHICH REDUCE THESE LOSSES
Wind resistanceTubular shaft for decreased wind resistance
Accelerations of oar massLow total weight and more importantly, low rotational inertia
Handling losses (i.e. crabs, poor releases, blade dragging on recovery)Ease of handling achieved by means of blade design and precision molded sleeve and oarlock
Work lost to the water through propulsive inefficiencyBlade designs including Big Blade and Smoothie for improved propulsive efficiency
