Originally made from wood, shells are now almost always made from a composite material (usually a double skin of carbon-fibre reinforced plastic with a sandwich of honeycomb material) for strength and weight advantages. FISA rules specify minimum weights for each class of boat so that no individual team will gain a great advantage from the use of expensive materials or technology.
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!!!
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).

Rowing has long been recognized as the perfect aerobic pursuit, with naturally smooth and flowing movements that don't tax the joints but do boost the heart rate. Now you can take your rowing experience to the next level with the WaterRower Natural rowing machine. Using the same principles that govern the dynamics of a boat in water, the WaterRower Natural is outfitted with a "water flywheel" that consists of two paddles in an enclosed tank of water that provide smooth, quiet resistance, just like the paddles in an actual body of water. As a result, the machine has no moving parts that can wear out over time (even the recoil belt and pulleys don't require lubricating or maintaining). More significantly, the water tank and flywheel create a self-regulating resistance system that eliminates the need for a motor. As with real rowing, when you paddle faster, the increased drag provides more resistance. When you paddle slower, the resistance is less intense. The only limit to how fast you can row is your strength and your ability to overcome drag. And unlike conventional rowing machines, which tend to be jerky and jarring, the WaterRower Natural is remarkably smooth and fluid.
Whilst the action of rowing and equipment used remains fairly consistent throughout the world, there are many different types of competition. These include endurance races, time trials, stake racing, bumps racing, and the side-by-side format used in the Olympic games. The many different formats are a result of the long history of the sport, its development in different regions of the world, and specific local requirements and restrictions.
Blades, otherwise known as oars to amateurs or non rowers, are used to propel the boat. They are long (sculling: 250–300 cm; sweep oar: 340–360 cm) poles with one flat end about 50 cm long and 25 cm wide, called the blade. Classic blades were made out of wood, but modern blades are made from more expensive and durable synthetic material, the most common being carbon fiber.
Both competitive and recreational rowing are unique in comparison to most sports because they exercise all of your major muscle groups. Everything from your legs, back, and arms are engaged while rowing. In addition, rowing is a low-impact sport. When executed properly, the rowing stroke is a fairly safe motion, providing little room for the serious injury often found in contact and high-impact sports. 1
Rowing events use a systematic nomenclature for the naming of events, so that age, gender, ability and size of boat can all be expressed in a few numbers and letters. The first letter to be used is 'L' or 'Lt' for lightweight. If absent then the crew is open weight. This can be followed by either a 'J' or 'B' to signify junior (under 19 years) or under 23 years respectively. If absent the crew is open age (the letter 'O' is sometimes used). Next is either an 'M' or 'W' to signify if the crew are men or women. Then there is a number to show how many athletes are in the boat (1,2,4 or 8). An 'x' following the number indicates a sculling boat. Finally either a + or – is added to indicate whether the boat is coxed or coxswainless.
