Rowing at the 2000 Summer Olympics – Men's lightweight coxless four
The men's lightweight coxless four competition at the 2000 Summer Olympics in Sydney, Australia took place at the Sydney International Regatta Centre.
Competition format
This rowing event is a sweep rowing event, meaning that each rower has one oar and rows on only one side. Four rowers crew each boat, and no coxswain is used. As a lightweight rowing event, rowers were limited to a maximum body mass of 72.5 kilograms each and 70 kilograms on average. The competition consisted of multiple rounds. Finals were held to determine the placing of each boat; these finals were given letters with those nearer to the beginning of the alphabet meaning a better ranking. Semifinals were named based on which finals they fed, with each semifinal having two possible finals.With 14 boats in with heats, the best boats qualify directly for the semi-finals. All other boats progress to the repechage round, which offers a second chance to qualify for the semi-finals. Unsuccessful boats from the repechage are eliminated from the competition. The best three boats in each of the two semi-finals qualify for final A, which determines places 1–6. Unsuccessful boats from semi-finals A/B go forward to final B, which determines places 7–12.
