Decreasing  speed of waves as water becomes shallow has dramatic consequences on the beach. As the waves slow, their profile (Figure on right) is laterally compressed and since each wave must carry the same energy it becomes higher. As the wave approaches shore this process continues until the height exceeds 1/7 th the wave length and the wave becomes unstable. Then the wave breaks.
Balanced Tear-drop Handle: The handle of the WaterRower M1 LoRise is made of aluminum for strength and lightness, with a tear-drop shape that fits comfortably into the palm of the hand to minimize wrist torque - a common cause of tendonitis. Because of its strength and lightness, the drive strap of the WaterRower M1 LoRise is high-density polyester webbing, guided by nylon pulleys. The drive strap does not wear and is maintenance-free, requiring no messy lubrication.

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 WaterRower, unlike conventional indoor rowing machines, creates a non-impact and non-load bearing environment for cross-training and rehabilitation. The users weight is taken off the knees and ankles by the seated position of the exercise and the use of the unique WaterFlywheel creates an evenly loaded stroke eliminating the heavy jarring and loading experienced on conventional rowing machines, making the WaterRower a popular choice for physiotherapy and sports sciences practices around the world.
If you are anything like me, you read the negative reviews to see what some of the complaints could potentially be...I have found none that match with my machine or experience so far. The boxes it came in were a little bunged-up but everything on the inside was perfect. Only took about 15-20 minutes to build (first time building a row machine) and another 5-10 to fill with water. We used it for a little while before we added the danish oil.
This popular rowing machine utilizes magnetic resistance for a quiet, and very smooth workout. The Velocity Exercise CHR-2001 also features a programmable computer with 12 programs that will keep your exercising varied and challenging for years. The computer also provides data on distance, time, calories burned, pulse rate, strokes per minute, and stroke count. Additionally, the tension resistance is electronically controlled via the computer.  This electronic resistance control feature puts the CHR-2001 ahead of other magnetic rowers that tend to use knobs.
The WaterRower Natural is handcrafted in solid ash and stained honey oak for consistency of color. The wood was chosen due to its marvelous engineering properties, especially its ability to absorb sound and vibration, which enhances the WaterRower's quiet performance and smooth operation. Ash, like all woods used in the construction of the WaterRower, is a premium hardwood with incredible longevity and dimensional stability. In addition, the wood is harvested from replenishable forests and is hand finished with Danish oil to provide a deep luster.
Water rowers feature a tank that is actually filled with water as a means for resistance. As you increase the pace of rowing, the resistance naturally increases as well. This means that you can set your own pace and resistance in a single motion. The same is true for air rowers. Air rowers use a fan or flywheel to create resistance, and you have control over the intensity of the workout due to the fact that the air resistance depends on your pace. Most water and air rowers come equipped with -- or at least have as an option -- monitors that track various functions such as distance, strokes, strokes per minute and calories burned.
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.

The table on the left gives the speed of waves of different wave lengths in deep water. “Deep” in this context is not an absolute value, but is relative to wave length. The simple relationship starts to to breakdown when the depth of the water is less than 1/4 th the wave length. At that depth the bottom exerts sufficient drag on the wave to slow its motion and thus decrease the wavelength [equations and more about wave speed].
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.
