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.

Performance is meaningless if you can’t or don’t want to use the equipment, and that’s why the Wave Water rower was built for comfort and convenience. With a wide, molded seat to accommodate users of all sizes and a padded, textured rowing handle, you can build your strength and endurance in ease. When setting up the rower, the leveling endcaps with a dial ensure stability. After your workout, storing your Wave Water rower is easy – just fold the frame and roll the rower into a closet or corner.


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]
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.

If you’re new to rowing, start off slow and begin with a five to ten-minute warm-up, followed by a twenty-minute workout and five to ten additional minutes for the cool down. During your workout, if you continue to consistently row at the same speed, over a period of a few sessions you should begin to notice an increase in your endurance. For a more intense workout, you can try interval training with your rower. Start off each workout by rowing for five to ten minutes at the highest resistance level, as fast as you can. Next, for two to three minutes row slowly, at the lowest resistance setting. Do this for thirty to sixty minutes. Interval training has been incorporated in many different types of exercise from cardio to strength training, and it’s designed to give your metabolism a jolt and make your body improve its fat burning abilities
After reading so many fantastic reviews I purchased the Classic model. Before I write what I think are the negative aspects I'll say that it gives a great workout! That is pretty obvious and I don't think that part is arguable. The disappointment began while unpacking. The wood parts were wrapped fairly well and did not have damage but there were several scratches that I had to sand out and re-oil. It appears that they were there before shipping. Putting it together would have been fast and easy- except 2 of the bolts were bent at about 15 degrees and would not fit. I had to wrap with tape and bend with vice grips. After getting it all together the rower worked well for about a week. I started to notice an annoying kind of popping sound from the left rail as the wheels rolled over on each stroke and recovery. It seems the plastic that the wheels ride on is not flat or adhered well to the rail. It isn't very loud but I can hear it well and it gets my attention, spoiling the nice sound of the water. Really disturbing. Support at WaterRower would like a video of the issue. Seems like an obvious issue and could swap out with a rail that is good instead of me trying to make a video of this small sound while moving the seat back and forth. For a $1500 machine the quality control- or lack of it is disturbing. Having to jump through a bunch of hoops because they are too cheap to just send a part is even more so. Perhaps I am being difficult but it is upsetting to have something touted as so great but put together like a $200 piece of junk. Another complaint would be the lack of any back lighting on the monitor. Really cannot see it if the lights are low. Being able to remove the monitor to attach to a PC wouldn't hurt either. While it gives a good workout the rower really suffers from poor manufacturing.

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.

The WaterRower Classic is handcrafted from solid American Black Walnut wood, finished with 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

The most commonly damaged piece of rowing equipment is the skeg, which is a metal or plastic fin that comes out of the bottom of the boat to help maintain stability, and to assist in steering. Since the skeg sticks out below the hull of the boat it is the most vulnerable to damage, however it is relatively easy to replace skegs by gluing a new one on. Hull damage is also a significant concern both for maintaining equipment, and for rower safety. Hull damage can be caused by submerged logs, poor strapping to trailers, and collisions with other boats, docks, rocks, etc.
Rowing machines are an excellent and effective way to get exercise and muscle tone, thanks to their sliding seat and repetitive rowing motion, that allows the engagement of almost all major muscle groups, without the need for a lot of gear or a lot of space compared to most workout machines. Long renowned as the perfect aerobic exercise, the WaterRower is unmatched with its ability to burn calories within a perceived level of exertion. Low impact and body weight bearing, the WaterRower is perfect for any user, and each one is built from beautiful, rich wood that is sourced only from sustainably-managed forests where growth exceeds removal by 229%.
Motion of the water is different than the motion of the wave. Water at each location moves in a circular path, but the motions at different locations are “out of phase”, which means that when water at the left of the diagram is moving to the right, water a quarter of a wavelength to the right is moving down, and water next to it is moving to the left, and next to it is moving up, etc. The overall effect is a an “apparent” wave moving to the right. Thus, the velocity (speed) of a wave is not at all the same as the velocity of the water.

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].
There is some minor maintenance. Because it's made out of wood, which can expand and contract, the bolts need tightening every few months or so. It's easy and takes only a couple of minutes. That, and putting in a fresh water purification tablet every six to twelve months, are about it for regular maintenance. The only problem I've had with the rower (the reason for 4 stars instead of 5) was a squeak that developed after about 6 weeks. It took me some time to determine the source of the squeak, which was a metal bracket connecting the footrest board to the horizontal boards above the drum. I had to partially disassemble the top section and tighten four bolts, but that fixed the problem and it's been quiet ever since.

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.

Ergometer rowing machines (colloquially ergs or ergo) simulate the rowing action and provide a means of training on land when waterborne training is restricted, and of measuring rowing fitness. Ergometers do not simulate the lateral balance challenges, the exact resistance of water, or the exact motions of true rowing including the sweep of the oar handles. For that reason ergometer scores are generally not used as the sole selection criterion for crews (colloquially "ergs don't float"), and technique training is limited to the basic body position and movements. However, this action can still allow a comparable workout to those experienced on the water.
The Challenge AR has the capability to allow the rower to control and adjust the resistance from “Feather light” to “Olympic sprint” delivering a silky smooth resistance to the user’s effort and instantaneous response to input with no “flat sport”.  With water resistance being the most accurate manner in which to simulate actual outdoor rowing, the Challenge AR provides a smooth and consistent sensation throughout the range of motion of the exercise experience.

The first international women's races were the 1954 European Rowing Championships.[54] The introduction of women's rowing at the 1976 Summer Olympics in Montreal increased the growth of women's rowing because it created the incentive for national rowing federations to support women's events. Rowing at the 2012 Summer Olympics in London included six events for women compared with eight for men.[55] In the US, rowing is an NCAA sport for women but not for men;[56] though it is one of the country's oldest collegiate sports, the difference is in large part due to the requirements of Title IX.

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.
