Rowing is a cyclic (or intermittent) form of propulsion such that in the quasi-steady state the motion of the system (the system comprising the rower, the oars, and the boat), is repeated regularly. In order to maintain the steady-state propulsion of the system without either accelerating or decelerating the system, the sum of all the external forces on the system, averaged over the cycle, must be zero. Thus, the average drag (retarding) force on the system must equal the average propulsion force on the system. The drag forces consist of aerodynamic drag on the superstructure of the system (components of the boat situated above the waterline), as well as the hydrodynamic drag on the submerged portion of the system. The propulsion forces are the forward reaction of the water on the oars while in the water. Note also that the oar can be used to provide a drag force (a force acting against the forward motion) when the system is brought to rest.
Modern rowing as a competitive sport can be traced to the early 10th century when races were held between professional watermen on the River Thames in London, United Kingdom. Often prizes were offered by the London Guilds and Livery Companies. Amateur competition began towards the end of the 18th century with the arrival of "boat clubs" at the British public schools of Eton College, Shrewsbury School, and Westminster School. Similarly, clubs were formed at the University of Oxford, with a race held between Brasenose College and Jesus College in 1815. At the University of Cambridge the first recorded races were in 1827. Public rowing clubs were beginning at the same time; in England Leander Club was founded in 1818, in Germany Der Hamburger und Germania Ruder Club was founded in 1836 and in the United States Narragansett Boat Club was founded in 1838 and Detroit Boat Club was founded in 1839. In 1843, the first American college rowing club was formed at Yale University.

Outside of resistance type, we found the number-one arbiter of ride feel to be cord quality. Water ergometers tend to employ nylon cords, while air ergometers feature metal chains — a durability factor we anticipated would result in our favoring air. But while all three water rowers aced our expectation of smooth, high-tension strokes, perfecting the chain seems to be more difficult: Some tug with just a slight rumble, others feature bouncy, grinding chains that are incredibly loud, something akin to angry snoring. As for nylon, the best wind and unwind like elastic silk — no slack, no sound, no catching, just perfectly even tension throughout the stroke.
