The graph below indicates approximately how long the oars should be relative to spread. The mechanical advantages of sliding seat rowing derive from both full extension of the legs to power the oars but also from the increase in mechanical advantage, and greater sweep that is obtained by using longer oars (sculls) pivoting on a fulcrom (the oarlocks) outboard of the boat. With lightweight oars, the weight of your hands on the handles will almost be enough to lift the blades from the water. These rails are formed of hard coat anodized 6061 aluminum extruded from our own custom die.
