In addition to this, certain crew members have other titles and roles. In an 8+ the stern pair are responsible for setting the stroke rate and rhythm for the rest of the boat to follow. The middle four (sometimes called the "engine room" or "power house") are usually the less technical, but more powerful rowers in the crew, whilst the bow pair are the more technical and generally regarded as the pair to set up the balance of the boat. They also have most influence on the line the boat steers.
The Challenge AR has the capability to allow the rower to control and adjust the resistance from “Feather light” to “Olympic sprint” delivering a silky smooth resistance to the user’s effort and instantaneous response to input with no “flat sport”.  With water resistance being the most accurate manner in which to simulate actual outdoor rowing, the Challenge AR provides a smooth and consistent sensation throughout the range of motion of the exercise experience.  
Heavyweight rowers of both sexes tend to be very tall, broad-shouldered, have long arms and legs as well as tremendous cardiovascular capacity and low body fat ratios. Olympic or International level heavyweight male oarsmen are typically anywhere between 190 cm and 206 cm (6'3" to 6'9") tall with most being around 198 cm (6'6") and weighing approximately 102 kg (225 lb) with about 6 to 7% body fat.
After reading so many fantastic reviews I purchased the Classic model. Before I write what I think are the negative aspects I'll say that it gives a great workout! That is pretty obvious and I don't think that part is arguable. The disappointment began while unpacking. The wood parts were wrapped fairly well and did not have damage but there were several scratches that I had to sand out and re-oil. It appears that they were there before shipping. Putting it together would have been fast and easy- except 2 of the bolts were bent at about 15 degrees and would not fit. I had to wrap with tape and bend with vice grips. After getting it all together the rower worked well for about a week. I started to notice an annoying kind of popping sound from the left rail as the wheels rolled over on each stroke and recovery. It seems the plastic that the wheels ride on is not flat or adhered well to the rail. It isn't very loud but I can hear it well and it gets my attention, spoiling the nice sound of the water. Really disturbing. Support at WaterRower would like a video of the issue. Seems like an obvious issue and could swap out with a rail that is good instead of me trying to make a video of this small sound while moving the seat back and forth. For a $1500 machine the quality control- or lack of it is disturbing. Having to jump through a bunch of hoops because they are too cheap to just send a part is even more so. Perhaps I am being difficult but it is upsetting to have something touted as so great but put together like a $200 piece of junk. Another complaint would be the lack of any back lighting on the monitor. Really cannot see it if the lights are low. Being able to remove the monitor to attach to a PC wouldn't hurt either. While it gives a good workout the rower really suffers from poor manufacturing.

Not a lot to complain about on the Classic rower, but when searching for drawbacks of this rowing machine, the S4 Monitor is the one thing that occasionally comes up.  It’s rather basic and it isn’t backlit. Regardless, the monitor has all necessary tracking and features for getting an excellent workout, and in normal lighting there is no problem reading the display.
Rowing, often referred to as crew in the United States,[1] is a sport whose origins reach back to Ancient Egyptian times. It involves propelling a boat (racing shell) on water using oars. By pushing against the water with an oar, a force is generated to move the boat. The sport can be either recreational for enjoyment or fitness, or competitive, when athletes race against each other in boats.[2] There are a number of different boat classes in which athletes compete, ranging from an individual shell (called a single scull) to an eight-person shell with coxswain (called a coxed eight).

Other details include dual rails with four corner wheels that increase seat stability and reduce the amount of sweat buildup; a frame that flips upright for handy storage; and a weight capacity of up to 1,000 pounds. The WaterRower Natural measures 84 by 21 by 22 inches (W x H x D), weighs 117 pounds (with water), and carries a one-year warranty on the frame and components (WaterRower will upgrade the warranty to five years on the frame and three years on the components with the completion of a registration form).

On theme with C2’s interchangeability, models D or E are essentially the same machine. When we talk about one we’re talking about both. The Concept 2 E is just 8 pounds heavier but is made out of stronger stuff all around — what’s plastic on the model D is aluminium on the model E, and what’s aluminum on the model D is welded steel on the model E. The only noticeable variations are seat height and display position.
The First Degree Newport rower utilises water resistance for a more effective workout that’s low impact, so it’s gentle on the body. You’ll focus on building up all the major muscle groups as you use a machine that offers a very realistic rowing experience.To increase resistance flip the valve control to add more water to the paddle water tank. To decrease resistance, remove water from the tank and enjoy a less challenging stroke for the cool down or warm up a portion of your workout. The tank on the Newport can hold a minimum of nine litres of water and a maximum of seventeen litres.

We facebooked customer service(They advertise this as one way to get a hold of them). The next day, they responded that we need to e-mail or call. We e-mailed customer service the other day. They asked for this video, and they haven't responded again since. I don't think it's too much to ask that a $500 piece of exercise equipment that's brand new could actually be usable.

The Challenge AR features an advanced computer monitor providing the rower with measurable performance output, an ergonomically designed seat that rides on precision bearings and rollers for absolute smoothness, an upgraded footboard with advanced heel support, and an innovative soft grip handle to eliminate stress on the hands and wrist during the comfortable, but physical workout.
Unfortunately, the direction of water movement at the top and bottom of the wave (thick arrows) rotate the boat in the direction you don’t want to go. As you realize this you try to pull your down-hill oar up out of the water, but this just pulls you over more in the bad direction. I spare you, gentle reader, a picture of the result. As the wave carries your boat up to a crest you try to lean into it to keep the boat level, but it’s natural to also push down on the down-hill oar to help.
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.
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 Classic rowing machine. Using the same principles that govern the dynamics of a boat in water, the WaterRower Classic 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 Classic is remarkably smooth and fluid.

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.
