First of all, if you're considering rowing, just do it. It is by far the most enjoyable and beneficial exercise I have ever tried. I've made huge strides with both cardio and muscle fitness with the WaterRower, and it's so enjoyable I look forward to exercising each day. Yes, it is more expensive than most other rowing machines, but when you compare it to a lot of other types of exercise equipment, it's actually pretty reasonable. When you also compare the exercise benefit you get, it's a bargain.
Ever since the earliest recorded references to rowing, the sporting element has been present. An Egyptian funerary inscription of 1430 BC records that the warrior Amenhotep (Amenophis) II was also renowned for his feats of oarsmanship. In the Aeneid, Virgil mentions rowing forming part of the funeral games arranged by Aeneas in honour of his father.[10] In the 13th century, Venetian festivals called regata included boat races among others.[11]

* While there is nothing to adjust from row to row on the WaterRower, it is possible to increase or decrease the level of resistance by changing how much water you put in the drum. The monitor is pre-calibrated to match 17 liters of water, but you can change that if you want. More than 17 liters = more resistance, up to the max fill line. This is not something you'll want to change frequently, it's more of a set-it-and-forget-it thing.

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.
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, 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).
In general, multi-boat competitions are organized in a series of rounds, with the fastest boats in each heat qualifying for the next round. The losing boats from each heat may be given a second chance to qualify through a repechage. The World Rowing Championships offers multi-lane racing in heats, finals and repechages. At Henley Royal Regatta two crews compete side by side in each round, in a straightforward knock-out format, with no repechages.
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].
According to fitness experts, water resistance is by far the most efficient technology used in a rowing machine, and the result is a realistic rowing experience that provides a better workout with smoother and more fluid rowing. These machines use a paddle that’s suspended in a tank of water, providing a realistic sensation of rowing outdoors. Extremely quiet running, as you row the only sound you’ll hear is the gentle splashing of water moving with each stroke, which serves to enhance the realistic experience of this style of rower.
Do you need a machine that folds up? If you've decided to avoid a water rower for space reasons, you may prefer a model that folds up for storage. Even better, some rowing machines have wheels fitted to them, so that once it's folded up, you can steer it to a storage space out of the way. You can find a foldable design in many magnetic and some air rowers.
The WaterRower Oxbridge is hand crafted in solid Cherrywood. Like all woods, Cherrywood may vary in color from a red-brown to deep red. The wood will darken in color with exposure to light. For this reason all WaterRower Cherrywood components are kept in light free rooms to protect from shadowing. A new WaterRower Oxbridge will therefore appear quite light in color. The wood will however darken over time reaching a rich reddish hue. Each machine has been hand finished with three coats of Danish Oil giving a deep lustre an warmth to the wood. Wood has been chosen due to its marvellous engineering properties, primary amongst these is its ability to absorb sound and vibration enhancing the WaterRower's quietness and smoothness of use. Cherrywood, like all woods used in WaterRower construction, is a premium hardwood with incredible longevity and dimensional stability. For reasons of ecology, all our woods are harvested from replenishable forests.
When waves run into water moving in the opposite direction, they are slowed, just as if they were approaching a beach. Wave length becomes shorter, wave height higher, and they may break. A good (bad) example of this is an ebb current flowing out of Raccoon Strait into waves coming in from the Golden Gate. Good rough water training, if that’s what you want.
