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].

John Duke, creator of the WaterRower, was inspired to try his hand at invention while working at a subsidiary for U.S. Steel. He wanted to make an indoor machine that felt as much like real rowing as possible, with a focus on aesthetics. It took him two years to get the design right, moving past failed ideas such as a flipper in the tank instead of a clutch. What began as a series of doodles at his desk turned into a sculptural piece of exercise equipment that upends expectations in two ways: by bringing water indoors, and by looking elegant and artful when stored.
Water machines are generally quieter than air rowers - you can still hear the water moving in the tank, but users tend to find this a pleasant ambient noise. Water rowers also tend to require little maintenance. Because there's a tank full of water involved, however, these can be very heavy, and larger than most other rowers: if you have a smaller home, a less-than-permanent workout space, or you move frequently, these might not be best for you. And because they're so high-performing, they do come at a high cost.
Rowing is a highly aerobic activity which burns calories quickly and gives you a complete cardiocascular workout which is a great way to help your heart as well as tone your arms, legs, chest, back, and abs.  What most people don't realize is that Rowing improves joint health through a wide range of motion and relieves stress because it allows you to remove yourself from the world around you, to connect to the calm and quiet of the water, and to meditate through the rhythmic, repetitive motion of your stroke. Rowing is a great way to get Aerobic and Anaerobic benefits without even thinking about it. Rowing also provides a workout for a variety of different muscles and joints in your body. If you want to see improvements in both your cardio fitness levels and your overall strength, it can give you the desired results you're looking for.
According to Fritz Hagerman, Ph.D., a professor in the Biological Science Department at Ohio University, “Competitive rowers expended almost twice the number of calories on a 2,000-meter course as a runner in a 3,000-meter steeplechase.”1 However, since rowing is low impact, you will not experience the same wear and tear on your body that you would if you were a runner. Plus, you build strength in your upper body and core.
The WaterRower Natural rowing machine is handcrafted in solid ash wood, stained Honey Oak, and finished with Danish oil. Wood is an excellent material for this application due to its ability to absorb sound and vibration enhancing the WaterRower's smooth, quiet operation. The Natural, as with all WaterRowers, features patented WaterFlywheel technology, unrivaled in its replication of the resistance felt in on the water rowing.
THL: Stay a safe distance from vertical surfaces if there are significant waves present in the area. A passing boat or ship may generate big waves that escape your attention until there is no time to escape. An example is the North anchorage of the Golden Gate Bridge (but there are special cases, e.g. rough water classes or the OWRC regatta, when there is a fast flood coming through the Golden Gate, and it is useful to be close to the wall since the current is slower there).

As previously discussed, the rowing machine’s big advantage is that it provides more than just a cardio workout. It can definitely help you build muscle and lose weight. Compared to a treadmill, the rowing machine works most of your body. It will really hit your shoulders, core, quads, hamstrings, glutes, arms and back effectively while being low impact thus reducing the stress on your joints. Bigger muscles need more energy and will burn fat to get it, which of course leads to healthy weight loss.
It provides a pretty impressive cardiovascular workout that will leave you feeling rejuvenated and empowered at the same time. This is a water resistance model that allows you to smoothly cut through water using all the major muscle groups, without putting unnecessary strain on the lower back and joints. This is the perfect workout for users who cannot participate in high impact workouts.
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. The WaterRower's patented WaterFlywheel has been designed to emulate the exact dynamics as a boat moving through water; the objective of the exercise of rowing.
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.
A feature of the end of twentieth century rowing was the development of non-olympic multicrew racing boats, typically fixed seat-gigs, pilot boats and in Finland church- or longboats. The most usual craft in races held around the coasts of Britain during summer months is the Cornish pilot gig, most typically in the south-west, with crews of 6 from local towns and races of varying distances. The Cornish pilot gig was designed and built to ferry harbour and river pilots to and from ships in fierce coastal waters. The boat needed to be stable and fast with the large crew hence making it ideal for its modern racing usage. In Finland 14-oared churchboats race throughout the summer months, usually on lakes, and often with mixed crews. The largest gathering sees over 7000 rowers mainly rowing the 60 kilometres (37 mi) course at Sulkava[38] near the eastern border over a long weekend in mid July. The weekend features the World Masters churchboat event which also includes a 2 kilometres (1.24 mi) dash.[39]
The Verified Sustainable Hardwoods used for the WaterRower are sourced from the Appalachian Mountain region of the eastern United States, where planting rates exceed harvest rates by an average multiple of 2.29. The Appalachian Hardwood Timber resource includes more than 65.4 million acres in the eastern United States and provides the world with a bounty of the finest hardwood species.
At the junior level (in the United States), regattas require each rower to weigh in at least two hours before their race; they are sometimes given two chances to make weight at smaller regattas, with the exception of older more prestigious regattas, which allow only one opportunity to make weight. For juniors in the United States, the lightweight cutoff for men is 150.0 lb.; for women, it is 130.0 lb. In the fall the weight limits are increased for women, with the cutoff being 135 lb.
The first known "modern" rowing races began from competition among the professional watermen in the United Kingdom that provided ferry and taxi service on the River Thames in London. Prizes for wager races were often offered by the London Guilds and Livery Companies or wealthy owners of riverside houses.[10] The oldest surviving such race, Doggett's Coat and Badge was first contested in 1715 and is still held annually from London Bridge to Chelsea.[12] During the 19th century these races were to become numerous and popular, attracting large crowds. Prize matches amongst professionals similarly became popular on other rivers throughout Great Britain in the 19th century, notably on the Tyne. In America, the earliest known race dates back to 1756 in New York, when a pettiauger defeated a Cape Cod whaleboat in a race.[13]

The WaterRower Natural is handcrafted from solid Ash wood, finished with a honey oak stain and danish oil. The WaterRower's patented WaterFlywheel has been specifically designed to emulate the dynamics of a boat moving though water and is unsurpassed in its simulation of the physical and physiological benefits of rowing. WaterRower will not provide support or documentation for any product transported outside of the original country of purchase
This piece of finely tuned, hand-crafted, water-resistance workout equipment also sits at the top end of the rowing machine spectrum. Employing a water flywheel that helps to mimic the feel of rowing in actual water, the natural wood WaterRower Rowing Machine will bring you a smooth, yet challenging workout that is as tough as you want it to be. If rowing is one of the best exercises you can do for your body as far as natural motion with low to no-impact, then the WaterRower is one of the best machines to do it on.

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.

There is much to love about the WaterRower--and I do love it--but I would echo others' comments that although the seat rolls solidly and smoothly on the wood rails, the seat itself is very hard (I use a gel seat pad I bought for my hard fiberglass kayak seat), and the footpads are in need up rethinking and upgrading--the cheap plastic doesn't let you row in socks or barefoot and is not really worthy of a machine that is otherwise a stunning piece of engineering and a beautiful one as well. As one other person noted about his machine, my machine made a clicking noise on the return stroke, so I had to adjust the wheel underneath the top rail that connects to the footpad and pull it away gently from where it was rubbing against another component. Also, be warned: the instruction booklet is in the DVD case. I did not see the little sticker on the case telling me that, thinking I'd wait to watch the DVD until after I'd assembled it. But WaterRower has a copy of the assembly instructions on their website, along with a video (I found the written ones better and easier to follow), so I was able to assemble it with no difficulty.


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.
