The model E’s seat stands 6 inches higher. And while the model D’s monitor rests on an adjustable arm, the E’s sits on unbending metal. These few technical differences do nothing to impact ride feel. We recommend the $200-cheaper model D as the best buy, but the Concept 2 E will appeal to anyone who values a higher seat and more solid construction.
For a third option, you can look to hydraulic machines, which use pistons to generate resistance. Hydraulic rowers are quiet, and they also tend to be smaller and cheaper than other kinds of rowing machines, but you won’t get the same smooth rowing feel, or the consistency of resistance, that you would get with an air or water rower. What's more, reviewer after reviewer has found them unreliable and high-maintenance.
Rowing has long been recognized as the perfect aerobic pursuit, with naturally smooth and flowing movements that don't tax the joints but do boost the heart rate. Now you can take your rowing experience to the next level with the WaterRower Natural rowing machine. Using the same principles that govern the dynamics of a boat in water, the WaterRower Natural is outfitted with a "water flywheel" that consists of two paddles in an enclosed tank of water that provide smooth, quiet resistance, just like the paddles in an actual body of water. As a result, the machine has no moving parts that can wear out over time (even the recoil belt and pulleys don't require lubricating or maintaining). More significantly, the water tank and flywheel create a self-regulating resistance system that eliminates the need for a motor. As with real rowing, when you paddle faster, the increased drag provides more resistance. When you paddle slower, the resistance is less intense. The only limit to how fast you can row is your strength and your ability to overcome drag. And unlike conventional rowing machines, which tend to be jerky and jarring, the WaterRower Natural is remarkably smooth and fluid.
With magnetic rowing machines, adjusting the resistance means varying the distance between a flywheel and one or more strong magnets. This is done either manually, using mechanical sliders, or digitally by the console controls. Like hydraulic rowers, magnetic rowing machines operate quietly and have a compact design for easy storage. Unlike hydraulic rowers, they can provide a smooth and consistent workout. It's a very different kind of feel to what you'd expect from an air or water rower, though. You still get a good workout, but it doesn't simulate the sensation of rowing in quite the same way.

Storage is also a plus point for the Waterrower series as they are all designed to stand upright with the tank acting as ballast for stability. In this position they only take up around two square feet. Again, great if you are planning on training in the living room. However, if you have small children, I would advise fixing the top to the wall with a hook and strap.

How good is the display? What data does it show you? Tracking your progress is an important part of losing weight, improving your fitness, or striving towards almost any goal. That means that when choosing a rowing machine, you shouldn't forget to think about its display. You want a machine that will tell you - clearly and accurately - how many calories you've burned, how long you've worked out, your strokes per minute, and so on. Many rowing machines come with a heart rate monitor, too. Even if you have your own wearable fitness tracker, don't underestimate the value of being able to export data from your rowing machine.
The most commonly damaged piece of rowing equipment is the skeg, which is a metal or plastic fin that comes out of the bottom of the boat to help maintain stability, and to assist in steering. Since the skeg sticks out below the hull of the boat it is the most vulnerable to damage, however it is relatively easy to replace skegs by gluing a new one on. Hull damage is also a significant concern both for maintaining equipment, and for rower safety. Hull damage can be caused by submerged logs, poor strapping to trailers, and collisions with other boats, docks, rocks, etc.

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?

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.

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.
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.
As previously discussed, the rowing machine’s big advantage is that it provides more than just a cardio workout. It can definitely help you build muscle and lose weight. Compared to a treadmill, the rowing machine works most of your body. It will really hit your shoulders, core, quads, hamstrings, glutes, arms and back effectively while being low impact thus reducing the stress on your joints. Bigger muscles need more energy and will burn fat to get it, which of course leads to healthy weight loss.
