In deep water the speed (or velocity) of a water wave depends only on its wave length. Specifically, the speed is proportional to the square root of the wavelength. Thus, the longer the wave length, the faster the wave, or vice versa. The speed of a single wave is called the phase speed. Amazingly, the speed of a packet of waves (the group speed) is often not the same.
In sweep or sweep-oar rowing, each rower has one oar, held with both hands. This is generally done in pairs, fours, and eights. In some regions of the world, each rower in a sweep boat is referred to either as port or starboard, depending on which side of the boat the rower's oar extends to. In other regions, the port side is referred to as stroke side, and the starboard side as bow side; this applies even if the stroke oarsman is rowing on bow side and/or the bow oarsman on stroke side.

In the 1950s- and 1960s, more sports coaches began to use rowing machines for training and assessment of athletes' performance. One such rower developed at this time was the Harrison-Cotton machine, the brainchild of John Harrison of Leichhardt Rowing Club in Sydney and Professor Frank Cotton, produced by Ted Curtain Engineering. This was the very first piece of equipment able to measure athletic power with great accuracy, and it also imitated the actual experience of rowing more closely than any previous rowing machine.


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 Classic is hand crafted in solid American Black Walnut. Like all woods, Black Walnut may vary in color from a rich brown to purple-black. 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. Black Walnut, 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.
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.
The Waterrower has recently been made famous by Kevin Spacy as the rowing machine used in the ‘House of Cards’. It is a type of wooden rowing machine produced and manufactured by Waterrower Inc. in New England, USA. The rowers were designed by ex-US national team rower john Duke in the mid 1980’s and the company to manufacture them was established in 1988.
I am happy with this rowing machine..it is quiet and offers good resistence without puttong too much stress on my joints...HOWEVER...the electronic counter has NOT worked from day one!!!..pulling the handle does NOT activate the meter at all!...I hve pluged in the wires and repeated that process SEVERAL times..BUT...nothing!!...I can activate the meter manually...BUT...it is USELESS for registering any rowing activity!!..As I said...good rower....USELESS Eleconic meter!!!
Floating Heel-Rest Design: The Rowing Machine's footboard incorporates the all-new Floating Heel-Rest design. The cup of the heel-rest follows the heel as it rises from the footboard providing stability and comfort from the beginning to end of each stroke. The heel-rest position is adjusted simply by pressing the central button to disengage the lock pins securing the footpads.

Rowing is one of the oldest Olympic sports. Though it was on the programme for the 1896 games, racing did not take place due to bad weather,[4] but male rowers have competed since the 1900. Women's rowing was added to the Olympic programme in 1976. Today, only fourteen boat classes race at the Olympics: [note 2] Each year the World Rowing Championships is staged by FISA with 22 boat classes raced. In Olympic years only the non-Olympic boat classes are raced at the World Championships. The European Rowing Championships are held annually, along with three World Rowing Cups in which each event earns a number of points for a country towards the World Cup title. Since 2008, rowing has also been competed at the Paralympic Games.

The WaterRower Classic 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.
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.
