To attempt to reduce the effect of the Bushes Wind, the course was narrowed and pushed further to the centre of the river. The width was 135 feet in 1887, in 120 feet in 1888 and then progressively until by 1914 it was down to 100 feet at the start tapering to 80 feet at the finish. In 1899, floating booms secured between the pilings which mark the course were also introduced along part of its length in an attempt to keep spectators from obstructing races.
