Decreasing speed of waves as water becomes shallow has dramatic consequences on the beach. As the waves slow, their profile (Figure on right) is laterally compressed and since each wave must carry the same energy it becomes higher. As the wave approaches shore this process continues until the height exceeds 1/7 th the wave length and the wave becomes unstable. Then the wave breaks.

A rowing workout can produce sustainable results without negatively impacting muscles and joints. With a reported average of five hundred to a thousand calories burned per workout, rowing machines are the hottest new fitness trend in the industry. Because of this, manufacturers are working overtime to produce a wide variety of styles and types of row machines, all of which can offer an effective low-impact total body workout. With so many choices of models, it can be confusing for beginners to choose the right type. Most consumers automatically choose the cheapest rower, however, cheaper models often feature piston resistance, which is considered the worst type of technology because the workouts are uncomfortable and the machine itself is often poorly designed.
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.

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. 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. 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.
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 bumps race is a multi-day race beginning with crews lined up along the river at set intervals. They start simultaneously and all pursue the boat ahead while avoiding being bumped by a boat from behind. If a crew overtakes or makes physical contact with the crew ahead, a bump is awarded. As a result, damage to boats and equipment is common during bumps racing. To avoid damage the cox of the crew being bumped may concede the bump before contact is actually made. The next day, the bumping crew will start ahead of any crews that have been bumped. The positions at the end of the last race are used to set the positions on the first day of the races the next year. Oxford and Cambridge Universities hold bumps races for their respective colleges twice a year, and there are also Town Bumps races in both cities, open to non-university crews. Oxford's races are organised by City of Oxford Rowing Club and Cambridge's are organised by the Cambridgeshire Rowing Association.
Water rowers feature a tank that is actually filled with water as a means for resistance. As you increase the pace of rowing, the resistance naturally increases as well. This means that you can set your own pace and resistance in a single motion. The same is true for air rowers. Air rowers use a fan or flywheel to create resistance, and you have control over the intensity of the workout due to the fact that the air resistance depends on your pace. Most water and air rowers come equipped with -- or at least have as an option -- monitors that track various functions such as distance, strokes, strokes per minute and calories burned.
The meter didn't work properly. It wasn't keeping the distance - we would row for 30 mins and wouldn't even be at 1km!!! And the strokes per minute was reading double strokes (which the company said was normal - huh?). Their customer service team was good and tried to make it work but we ended up returning it and spent the extra money to get a WaterRower and it is amazing!!!
Rowers may take part in the sport for their leisure or they may row competitively. There are different types of competition in the sport of rowing. In the U.S. all types of races are referred to as regattas whereas this term is only used in the UK for head-to-head or multi-lane races (such as those that take place at Dorney Lake), which generally take place in the summer season. Time trials occur in the UK during the winter, and are referred to as Head races. In the US, head races (usually about 5k, depending on the body of water) are rowed in the fall, while 2k sprint races are rowed in the spring and summer.
