In the 1950s- and 1960s, more sports coaches began to use rowing machines for training and assessment of athletes' performance. One such rower developed at this time was the Harrison-Cotton machine, the brainchild of John Harrison of Leichhardt Rowing Club in Sydney and Professor Frank Cotton, produced by Ted Curtain Engineering. This was the very first piece of equipment able to measure athletic power with great accuracy, and it also imitated the actual experience of rowing more closely than any previous rowing machine.
Although the oar can be conveniently thought of as a lever with a "fixed" pivot point in the water, the blade moves sideways and sternwards through the water, so that the magnitude of the propulsion force developed is the result of a complex interaction between unsteady fluid mechanics (the water flow around the blade) and solid mechanics and dynamics (the handle force applied to the oar, the oar's inertia and bending characteristic, the acceleration of the boat and so on).
Here’s a secret, because the rowing machine provides an intense full body workout, the exercise burns a high amount of calories not only during the actual activity but also for a period after you’ve stopped. This is known as the “after-burn effect”. Essentially, you’ve worked your body so hard that it is forced to keep burning calories and fat even when you’re not rowing. The scientific jargon for this is “excess post-exercise oxygen consumption” or “EPOC” for short. But all you need to know is that if you’re doing an intense rowing workout, the benefits continue after you’re done. How great is that?

It's been nearly 30 years since John Duke, a former Yale University and USA National Team oarsman, set up a small shop in Rhode Island, USA to begin fine-tuning his innovative water-resistant rowing machine. With its beautiful design and unmatched feel, the WaterRower quickly gained a cult-like following of both on-water rowers and fitness enthusiasts that had found their perfect piece of workout equipment. As word spread of the new product that simulated the feel of on-water rowing, WaterRower transitioned from simply a one-off product found within the occasional boathouse to an established brand in both the rowing and fitness world.
From a fitness perspective, the WaterRower Classic works 84 percent of your muscle mass, helping tone and strengthen your muscles while burning far more calories than most other aerobic machines. The exercise is also low impact, as it removes all the body weight from the ankles, knees, and hips, but still moves the limbs and joints through a full range of motion--from completely extended to completely contracted.
With the smaller boats, specialist versions of the shells for sculling can be made lighter. The riggers in sculling apply the forces symmetrically to each side of the boat, whereas in sweep oared racing these forces are staggered alternately along the boat. The sweep oared boat has to be stiffer to handle these unmatched forces, so consequently requires more bracing and is usually heavier – a pair (2-) is usually a more robust boat than a double scull (2x) for example, and being heavier is also slower when used as a double scull. In theory this could also apply to the 4x and 8x, but most rowing clubs cannot afford to have a dedicated large hull which might be rarely used and instead generally opt for versatility in their fleet by using stronger shells which can be rigged for either sweep rowing or sculling. The symmetrical forces also make sculling more efficient than rowing: the double scull is faster than the coxless pair, and the quadruple scull is faster than the coxless four.
Wood is used for its unique visual appeal, but also for its ability to absorb sound vibration for smooth, quiet operation, as well as it's stable longevity. The Club edition rowing machine is handcrafted in solid ash wood and stained for color. It has been designed for high traffic or commercial areas, and its black rails have been styled to prevent scuffing. The other wooden components are finished in an attractive rosewood which is more resistant to soiling than the Natural model. Each machine has also been hand finished with Danish Oil and Urethane for protection.
