Floating Heel-Rest Design: The Rowing Machine's footboard incorporates the all-new Floating Heel-Rest design. The cup of the heel-rest follows the heel as it rises from the footboard providing stability and comfort from the beginning to end of each stroke. The heel-rest position is adjusted simply by pressing the central button to disengage the lock pins securing the footpads.
1.) I keep reading about cracks and leaks that develop in the water tank. WaterRower even offers a tank repair kit for this very issue. It seems to me that this is a design flaw that they refuse to address, instead offering a fix for when it eventually occurs. Have you seen these tanks to eventually leak? I’m surprised they haven’t tried a one-piece tank.
Fetch is the distance over which the wind interacts with the water surface to creates waves. The longer the fetch the bigger (higher) the waves are. If the shore (green in the diagram) is a hill, there will be a wind shadow which gives protection from the wind, but even if the shore is flat as a pancake and gives no protection, the waves become progressively smaller as you for upwind to the shore. Thus, rowing upwind toward shore is always an escape from waves.
A bumps race is a multi-day race beginning with crews lined up along the river at set intervals. They start simultaneously and all pursue the boat ahead while avoiding being bumped by a boat from behind. If a crew overtakes or makes physical contact with the crew ahead, a bump is awarded. As a result, damage to boats and equipment is common during bumps racing. To avoid damage the cox of the crew being bumped may concede the bump before contact is actually made. The next day, the bumping crew will start ahead of any crews that have been bumped. The positions at the end of the last race are used to set the positions on the first day of the races the next year. Oxford and Cambridge Universities hold bumps races for their respective colleges twice a year, and there are also Town Bumps races in both cities, open to non-university crews. Oxford's races are organised by City of Oxford Rowing Club[41] and Cambridge's are organised by the Cambridgeshire Rowing Association.

The advantages with air rowers is that there is smooth action; there is only small wear and tear to its mechanism; its automatic feature adjusts according to your rate of strokes; and there is a wide range of the resistance readily available in replicating the feel of rowing through the waters. The only disadvantage of this machine is that it tends to be noise indoors.
The Concept2 Model D is the ultra-popular air rower that you’ll see at most gyms. It is one of the best home indoor rowers you can buy period. Expertly constructed and ergonomically unequaled, this rowing machine looks great and rows smoothly without so much as a jarring catch. As an air rower, the Concept2 employs air baffles to create the resistance. A nickel-plated chain pulls the flywheel and you get your workout by pulling against the increasingly higher air pressure that the fan is creating.
The WaterRower Classic Rower is outfitted with a Series 4 performance monitor that's designed to balance technical sophistication with user-friendliness. The monitor--which includes six information and programming windows, six QuickSelection buttons, and three navigation buttons--displays your workout intensity, stroke rate, heart rate, zone bar, duration, and distance. Plus, the monitor is compatible with an optional heart rate chest strap and receiver, which helps you optimize your workout and achieve your exercise objectives.
Noise level is another large factor that tips the scale more towards water rowers. Air rowers make a fairly loud “whooshing” noise every stroke, which makes them bad for people who like watching TV, have sleeping children, live in apartments, or like working out early in the AM. Water rowers do make some noise but the splashing of water in the tank is a lot quieter and more soothing than the fan noise produced by air rowers.
There are 4 main rowing machine types that are classed according to its utilized resistance mechanism. Having an exercise workout needs to have resistance against the movement in order to provide to the muscles and the cardiovascular system a good change. This can be provided by the rowing machine whenever you pull its handle and then slide back to the seat. Having low resistance works on the cardiovascular system can make you row fast easily. Having high resistance means that it provides you with the anaerobic session, working with the muscles harder, also having a slow stroke rate because of the harder pull.

One downside of the Waterrower for me are the footrests. Whilst they are perfectly adequate if you want to row in shoes, rowing barefoot, which is something I like to do, is impossible. The plastic is completely square at the bottom and has sharp edges that cut into your heels. I also found that my shoes get caught when trying to put them in and out of the holders, which is a bit irritating.
The main advantages of the water rower are that it has quiet operation; there is only little maintenance to do, the water only needs to be changed occasionally; many users love the whooshing sound of water in the tank; and its consistently smooth resistance at every stroke. Two disadvantages of this machine are it costs a lot than the air rower; and it tends to be larger in size compared to the other rowing machines.
Function plays a large role in defining good design. When designers look at an object, they don't just consider its aesthetic appearance; they should also challenge it to be more versatile, to respond to the user's need, or to achieve its purpose more elegantly. Good design has the capacity to solve problems that sometimes we didn't even know we had. This is one of the ways design touches and enriches our everyday life.
