Originally made from wood, shells are now almost always made from a composite material (usually a double skin of carbon-fibre reinforced plastic with a sandwich of honeycomb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.
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 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. 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.
Fetch is the distance over which the wind interacts with the water surface to creates waves. The longer the fetch the bigger (higher) the waves are. If the shore (green in the diagram) is a hill, there will be a wind shadow which gives protection from the wind, but even if the shore is flat as a pancake and gives no protection, the waves become progressively smaller as you for upwind to the shore. Thus, rowing upwind toward shore is always an escape from waves.
The WaterRower Classic Rower has been designed to optimize ease of storage. Simply lift one end and the machine stores conveniently upright in about the space of a dining room chair. The WaterRower Classic Rower has a light wooden frame, the positioning of the WaterFlywheel close to the wheels, and the leverage effect provided by the rails, makes lifting almost effortless. When stored the WaterRower's patented WaterFlywheel provides a low center of gravity making the machine very stable.
The first international women's races were the 1954 European Rowing Championships. 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. In the US, rowing is an NCAA sport for women but not for men; though it is one of the country's oldest collegiate sports, the difference is in large part due to the requirements of Title IX.
