THE COMPETITION

There are eight men's and six women's events, including three lightweight races in which there is a maximum weight limit of 59kg for a single woman, a 57kg average for a female crew, a maximum 72.5kg for men and an average of 70kg for a male crew.

The men compete in: single sculls, double sculls, lightweight double sculls, quadruple sculls, coxless pair, coxless four, lightweight coxless four and eight.

The women compete in: single sculls, double sculls, lightweight double sculls, quadruple sculls, coxless pair and eight.

Races are divided into two classes of boat (or shell): sculls - involving an oar in each hand - and sweep oar - involving just one oar. Rowers sit with their backs to the direction in which they are travelling and the oars are fixed in a fulcrum - where canoeists face the way they are travelling and the paddle is free.

Boats have one, two, four or eight rowers. The eights have a cox, who sits at the front of the crew to steer the boat and direct the crew. In other boats steering is carried out by one rower who operates a small rudder with a foot pedal.

In each event, crews are divided into groups and race over four days. All boats must race in heats, a losers' division race sometimes follows, with the top finishers from heats and losers' races advancing to semi-finals or a six-boat final. Whether there is a losers' race depends on how many boats are entered.

There is a drawn out procedure at the start of races to ensure all crews start evenly. Once the starter has called "two minutes", the crews must steady themselves in their starting boxes and are under starter's orders. Once all crews are steady, the starter shouts out a roll call by lane. If all is still steady and well, the starting judge's light shines white (red if there is a problem) and the starter shouts "attention", pauses and sounds an electronic klaxon. The boot which holds the bow of boats steady falls into the water and the race begins. Two false starts result in disqualification.

The finish is snapped by electronic photography and a horn sounds as each boat passes the finish line. Ties result in the same place being awarded in a final but a second race is rowed in qualification rounds, two hours after the original tussle.

The course in Sydney is a standard man-made 2,000 metres flat-water course more than 3.5 metres deep and with nine lanes, six of which are used for racing. The lanes are 13.5 metres wide and divided by coloured buoys, much like a giant swimming pool without the wave-breaker technology.

The buoys are red for the first 100 metres, change colour for the next 150 metres and again for the next 250 metres, after which two colours alternate every 250 metres, until the last 250 metres stretch, which is marked by a fourth colour, which in turn gives way to the final 100 metres of the course, marked in red.

The idea of man-made courses is to eliminate the worst elements of nature and other obstructions. Guidelines stipulate that courses should be well sheltered from wind, must not be bordered by buildings, hills and other obstructions that could alter wind patterns and give one crew an advatange over another, while sloping gravel banks are encouraged, as they act as wave-breakers.
