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].
The WaterRower Natural is hand crafted in solid Ash and stained Honey Oak for consistency of color. Each machine has been hand finished with 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.
It's been nearly 30 years since John Duke, a former Yale University and USA National Team oarsman, set up a small shop in Rhode Island, USA to begin fine-tuning his innovative water-resistant rowing machine. With its beautiful design and unmatched feel, the WaterRower quickly gained a cult-like following of both on-water rowers and fitness enthusiasts that had found their perfect piece of workout equipment. As word spread of the new product that simulated the feel of on-water rowing, WaterRower transitioned from simply a one-off product found within the occasional boathouse to an established brand in both the rowing and fitness world.
When feet are in position and you are seated, ensure you are sitting in a tall yet relaxed position. Try to feel as if you are sitting on your ‘sit’ or ischia bones and rock slightly forwards and backwards on these bones. Your body weight will move from the front to the back of the seat. Ensure you are sitting with a locked core, shoulders relaxed and head looking forwards.

This elegant rowing machine builds strength and stamina by closely simulating a real world rowing experience. Its patented Waterflywheel, which moves through actual water, provides a smooth stroke that exercises 84% of your muscle mass evenly and prevents injuries. When not in use, the WaterRower can be stored vertically against a wall. Made in the USA from ethically sourced walnut wood. Assembly required.

The machine was easy to put together and worked well mechanically. The problem is the electronic monitor. The strokes/min registered as double the actual pace, and the distance registered as 1/10th the actual distance. I contacted customer support via email and their response was slow and inadequate. I am returning the machine and plan to buy a WaterRower.
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 Rower will therefore appear quite light in color. The wood will however darken over time reaching a rich reddish hue.

The rowing machine itself is unlike any other on the market with its patented water filled flywheel. It is hard to exactly copy the action of a scull on the water, but the mechanics of the flywheel spinning in water comes in a close second on dry land. The fact that the water is 800 times denser than air means that there is no need for any extra resistance or dampening that you will find in normal air rowers. The faster you pull, the more resistance is generated giving it infinite variability. However, if you want to be able to practice rowing with a faster stroke, you will have to reduce the amount of water in the tank unlike an air rower where you just have to adjust the baffle.
The WaterRower Classic is handcrafted in solid American black walnut, which may vary in color from rich brown to purple/black. The black walnut 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. Black walnut, 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 three coats of Danish oil to give it a deep luster and warmth.
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.
