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].
Head races are time trial / processional races that take place from autumn (fall) to early spring (depending on local conditions). Boats begin with a rolling start at intervals of 10 – 20 seconds, and are timed over a set distance. Head courses usually vary in length from 2,000 metres (1.24 mi) to 12,000 metres (7.46 mi), though there are longer races such as the Boston Rowing Marathon and shorter such as Pairs Head.

Con's: Super bummed that for $1160 they couldn't include an internal ANT+ transponder and Heart Rate strap(sub $100 package). The foot straps are crap! Within the first 1000m of moderate rowing they loosen to the point of being able to pull foot out on Recovery of stroke(Yes, even with ball of foot down). I really wish the WaterCoach F.I.T. software for the S4 Monitor was macOS compatible. It'd be nice to able to customer program workouts on my MacBook Pro or iMac.

The Classic Rowing Machine is designed is extremely easy to use. Additionally, it has a lot of comfort features in its design. It has an ergonomically shaped handle and padded heel rests that accommodate nearly everyone. Everything on the machine can be adjusted quickly. Because there are no movement parts, maintenance is minimal. Even the computer has a lot of one button operations, so the minute you have the rower assembled, you can get to work.
The stake format was often used in early American races. Competitors line up at the start, race to a stake, moored boat, or buoy some distance away, and return. The 180° turn requires mastery of steering. These races are popular with spectators because one may watch both the start and finish. Usually only two boats would race at once to avoid collision. The Green Mountain Head Regatta continues to use the stake format but it is run as a head race with an interval start.[42] A similar type of racing is found in UK and Irish coastal rowing, where a number of boats race out to a given point from the coast and then return fighting rough water all the way. In Irish coastal rowing the boats are in individual lanes with the races consisting of up to 3 turns to make the race distance 2.3 km.

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.


As Stamina’s first water rower, the Wave Water Rowing Machine 1445 has all the necessities for a realistic, effective workout. Rowing on this machine feels and sounds like rowing in real life, making this a great option for those who are seeking an affordable water rower for indoor training. But even if you aren’t an avid oarsman or oarswoman, this machine truly offers a total body cardiovascular workout that’s enjoyable for everyone.

The distinction between rowing and other forms of water transport, such as canoeing or kayaking, is that in rowing the oars are held in place at a pivot point that is in a fixed position relative to the boat, this point is the load point for the oar to act as a second class lever (the blade fixed in the water is the fulcrum). In flatwater rowing, the boat (also called a shell or fine boat) is narrow to avoid drag, and the oars are attached to oarlocks ( also called gates ) at the end of outriggers extending from the sides of the boat.[8] Racing boats also have sliding seats to allow the use of the legs in addition to the body to apply power to the oar.

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.
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.

Although the oar can be conveniently thought of as a lever with a "fixed" pivot point in the water, the blade moves sideways and sternwards through the water, so that the magnitude of the propulsion force developed is the result of a complex interaction between unsteady fluid mechanics (the water flow around the blade) and solid mechanics and dynamics (the handle force applied to the oar, the oar's inertia and bending characteristic, the acceleration of the boat and so on).

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.
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).
If you are anything like me, you read the negative reviews to see what some of the complaints could potentially be...I have found none that match with my machine or experience so far. The boxes it came in were a little bunged-up but everything on the inside was perfect. Only took about 15-20 minutes to build (first time building a row machine) and another 5-10 to fill with water. We used it for a little while before we added the danish oil.

I kayak (ocean and flat water, not river), so I was drawn to the WaterRower over a flywheel type rower (which I have used in gyms) because I wanted to hear the sound of the water, which I miss hearing against the hull of the boat during the winter when I can't get out on the lake. I also like the way the paddles engage in the water; it's a very smooth pull and release, and moving the mass of the water instead of a dialed down tension feels more natural. As someone else also commented, the seat (at least on the wood version) is incredibly smooth and solid; no wobbling at all. I generally listen to music on my Nordic Track ski machine, but with the WaterRower I am content to listen to the sound of the water; working out on this is somehow both energizing and calmingly meditative at the same time. In the event that you want to use it while watching tv (this is one use to which I wanted to put it), it is quiet enough to hear the tv without having to turn it up.


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]

An 'oar' is often referred to as a blade in the case of sweep oar rowing and as a scull in the case of sculling. A sculling oar is shorter and has a smaller blade area than the equivalent sweep oar. The combined blade area of a pair of sculls is however greater than that of a single sweep oar, so the oarsman when sculling is working against more water than when rowing sweep-oared. He is able to do this because the body action in sculling is more anatomically efficient (due to the symmetry).
The WaterRower Club is hand crafted in solid Ash and stained for color. The WaterRower Club has been designed for High Traffic Areas such as Commercial Gyms, Studios, Rehabilitation Clinics, etc. Its Black Rails have been styled to prevent scuffing, other wooden components are finished in an attractive rosewood which is more resistant to soiling than the Natural model.
