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.

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.
The water flywheel is comprised of two paddles encased in an enclosed tank of water. As you pull the cable, the paddles move through the water creating resistance. The beauty of this machine is it uses the mass/density of water. The paddles create the drag, so the harder you pull, the more resistance increases. Think about moving your hands through water. The faster you go, the more dense water feels. The slower you go, the less you feel the resistance. And this type of resistance is excellent for your joints. Click here to read the full review.
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.
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]
Most races that are held in the spring and summer feature side by side racing, or sprint racing, sometimes called a regatta; all the boats start at the same time from a stationary position and the winner is the boat that crosses the finish line first. The number of boats in a race typically varies between two (which is sometimes referred to as a dual race) to eight, but any number of boats can start together if the course is wide enough.
One downside of the Waterrower for me are the footrests. Whilst they are perfectly adequate if you want to row in shoes, rowing barefoot, which is something I like to do, is impossible. The plastic is completely square at the bottom and has sharp edges that cut into your heels. I also found that my shoes get caught when trying to put them in and out of the holders, which is a bit irritating.
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 Water Rower comes partly preassembled in two large boxes. The assembly instructions are reasonably good, and as long as you take your time and follow them carefully (read all the text) it takes about 45 minutes from opening the first box to trying it out. I bought bottles of distilled water to fill it, which made it easy to fill using the included funnel & hose.

Proposition 65 requires businesses to provide Californians with a clear and reasonable warning about chemicals in the products they purchase, in their home or workplace, or that are released into the environment. By providing this information, Proposition 65 enables Californians to make informed decisions about protecting themselves from exposure to these chemicals. Proposition 65 also prohibits California businesses from knowingly discharging significant amounts of listed chemicals into sources of drinking water.

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.
