Core competencies include design and manufacturing high performance, premium, innovative rowing equipment. In 1982 Durham Boat was incorporate and soon began manufacturing carbon prepreg oars and other carbon rigging components for many OEM boat builders in the World. The most notable innovation was the adjustable handle feature for both rowing oars The "Tool Free" adjustment feature on the Alpha oar was introduced in 2015 that allows athletes to make fast (under 10 second) and easy on-the-water adjustments. This allows the athletes using this feature to change the load to adjust for varying wind conditions. A permanent molded carbon segmented screw on the shaft allows one centimeter of adjustment for every 360 degrees of rotation of the nut that is hand adjustable to move the bearing surface. To replace the bearing surface it is simply unscrewed off the shaft. No more difficult sleeve replacement required! The total length of the oar adjustment is adjusted with a self-contained lever that is also adjustable in < 10 seconds. In 2016 this feature was offered as an option on all adjustable length sculls and expanded to aerodynamic sweep oar in 2018, the Slim Ellipse sweep oar that has the sweep version of this feature as well as a new aerodynamic slim, elliptical sweep shaft, a new Apex-E blade shape.
