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].
WaterRower For over 20 years, WaterRower has been providing the world with rowing machines that demonstrate the physical and physi...ological benefits of rowing. Rowing is a complete aerobic exercise routine that works 84 percent of muscle mass and gives maximum results - you burn more calories in less time and have fun, too. Rowing combines aerobic exercise with resistance all in a smooth, rhythmic exercise. It's suitable for people of all shapes and sizes and is easy on the joints.WaterRower is committed to being environmentally conscious. Their rowing machines are made using only the world's finest hardwoods specially selected from replenishable sources where more wood is planted than harvested. Because WaterRower machines are people- powered, no electricity is required! WaterRower rowing machines help you burn calories, tone muscles, and be kind to the environment. read more
I kayak (ocean and flat water, not river), so I was drawn to the WaterRower over a flywheel type rower (which I have used in gyms) because I wanted to hear the sound of the water, which I miss hearing against the hull of the boat during the winter when I can't get out on the lake. I also like the way the paddles engage in the water; it's a very smooth pull and release, and moving the mass of the water instead of a dialed down tension feels more natural. As someone else also commented, the seat (at least on the wood version) is incredibly smooth and solid; no wobbling at all. I generally listen to music on my Nordic Track ski machine, but with the WaterRower I am content to listen to the sound of the water; working out on this is somehow both energizing and calmingly meditative at the same time. In the event that you want to use it while watching tv (this is one use to which I wanted to put it), it is quiet enough to hear the tv without having to turn it up.

Rowing machines were first used in Archaic Greece. Chabrias, an Athenian military general in 4th Century B.C., invented wooden rowing simulators for his inexperienced oarsmen. This enabled them to learn technique and timing before stepping foot on actual water crafts. And it must have worked — Chabrias successfully led numerous naval attacks against the Spartans.
Essentially, the water rower uses water as it's resistance and the air rower (click here to read our air rowing machine reviews) uses air resistance. Additionally, the resistance of the water gives a very similar feeling to actually rowing in the water. The rowing machines listed above all have fantastic rowing mechanisms that mimic the exact feeling of a rowing a boat.
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.
This type of calorie burn is better than what you would get from cycling or running, and it’s much gentler on the body. You can also position your hands differently in order to work new muscle groups in your lower and upper arms. Many people will be surprised to learn that rowing works the legs more than any other muscle group, but by switching up your rowing position, you can also focus on your abs, arms and shoulders for a total upper body workout that can provide impressive results just by working out a few times a week.
This type of machine provides a smooth action with little wear and tear to the mechanism, and the flywheel itself could help to keep you cool as you work out. It's worth noting that although water rowers aim for a realistic rowing feel, competitive rowers often use air rowers for land training. They tend to be less expensive than water-powered rowing machines, as well.
Rowing machines are often used by people who are looking to get a full-body workout, and also by rowers to stay in rowing shape during the off-season. According to Men’s Total Health, rowing is a natural motion, and is therefore fairly easy for anyone to pick up and do properly. Also, rowing is a low-impact exercise, meaning that the potential for injuries to your joints is lower than on such machines as treadmills, for example.
The resistance of your rowing machine impacts how it moves. Select from hydraulic and magnetic rowing resistance. Hydraulic rowers are typically more compact in size, while magnetic machines make little noise as they operate. Details like easy-to-reach tension knobs or buttons allow you to increase or decrease the intensity of your resistance as you train.
