E-H Sculling Oar Design: We came out with the E-H Sculling oar, with elliptical shape shaft and a new hydrodynamic blade shape with the goal to gain speed both on the recovery and during the drive. The new hydrodynamic blade has been tested for two years and we elected to install it on our aerodynamic shaft that can be economically produced. It is also being offered in the high modulus construction (i.e., called the E-HX). For more information see: Sculls Link: FAQ Facts on E-H Sculls as compared with the Aero and other oars.
 Foot Stretcher Design: We came out with the Universal RXT Shoe Plate: This is the Universal Rowing Cross Training Shoe Plate that will fit on many manufacturers boats. The shoe price depends on the stiffness, weight and comfort of the shoe selected, can used by a wide range of skilled rowers with the shoe plate economically priced. The key to this system is that the shoe does not stay with the boat. It is something that the rower chooses and can use on a daily basis for rowing or cross training. The shoe plate has a 10-degree toe to heel included-angle to allow better power transmission throughout the drive. The shoe snaps into stainless steel spring clips mounted to each side of the shoe on the shoe plate which can be easily released, but are not intended for self-releasing from the boat and relies on the heel tie down per USRA and FISA regulations. The shoes can also be fitted with Velcro straps. The shoe plate is compatible with several models of Adidas and K-Swiss shoes and others that allow for the attachment member that is added to shoe that provide side mounting of the shoes. The shoe performance is not adversely affected by the addition of this attachment member. It cannot be felt during rowing, walking or running, nor does it interfer with the bottom of the shoe in any manner. See one of the lighter weight Adidas models that is compatible with The Universal RXT Shoe plate on a Dreher Carbon Foot Stretcher Frame.

Oarlock Swivel Design: We came up with a new use for a swivel concept that dates backs to antiquity in the Greeks Triremes, where the Greek rowers rowed behind the pin to gain a mechanical advance. We postulated that this type of swivel that might work well to change the dynamics in the rowing tank to make the power application more like that which is seen in a boat.
The MVP Swivel or Modern Variable Power Swivel that allows handle acceleration toward the finish that occurs naturally in the boat due the boat acceleration from catch through release. This does not occur in a tank, however, due to much greater mass of water rotating at a constant speed. We have confirmed this what this new swivel does becuase is equipped with a Force Measurement sensors. This MVP Swivel goes along with other tank enhancements that came out in 2011 to improve the tank load and water circulation. More information can be found on the Dreher Indoor Rowing Facility Page.
 Rowing is an environmentally friendly sport and inherently has a low carbon footprint so we are pleased to be in a position where we can minimize our carbon footprint through this power generation project from a renewable resource. This philosophy of sustainability is something that has guided us for years. We have always tried to make products that are designed to not only perform exceptionally well, but also last a long time. We control the entire process from the design to manufacturing and in most cases the final assembly here in the USA. Since we first started making oars we have autoclaved our oar shafts and in so doing get greater longevity from the product. We also compression mold our blades and many of the boat parts that we make. Both processes pack the carbon and promote better resin transfer under high pressure that results in long lasting parts high quality parts. The less often you have to replace your oars or other carbon parts that we make, the lower your environmental impact. We offer a couple of rowing products (both ours and others) as metaphors: Those of you that love rowing probably do not like an oversized motor on a coach boat or any motorized boat out on the water. We have all appreciated the quiet and economical four cycle engine and wakeless hulls of the latest coach boats and do not mind paying a little more because it will benefit the environment and will save money long turn. For indoor training, pumped tanks are incredibly expensive and have higher operating cost for the life of the tank and yet you do not get the proper drive simulation that our latest design indoor rowing system does for a fraction of the cost and it uses no energy resources other than those of the athletes! Our new PV system is a metaphor for the premium quality designs and products that we make and the thought and workmanship that goes into every Dreher designed product. See the picture of our PV system being turned on and please flip a switch in your mind and endorse Dreher designed products Made in the USA, products that will last, will in the end reduce your carbon footprint, just as our new PV system will reduce ours!
