The Sydney-Hobart race: running down the coast

Posted by Rog on 17 December 2019 7:12:21 PM

Each year the Sydney-Hobart yacht race seems to get bigger and bigger, this year for the 75th anniversary 163 boats are registered to compete, the largest cohort since 1994.

In all classifications the winner will be determined by a combination of skilled sailing, and a bit of luck.

'Won and Lost' in the Derwent

How tricky currents play a part in the closing stages of the Rolex Sydney to Hobart Race

The last few miles of a Sydney to Hobart race has often determined the ultimate winner. Capricious, shifty wind and 'bullets' - gusts that come screaming down the steep hillsides lining the course are often to blame. Not to mention the notorious night time 'shut-down' - where the wind disappears entirely.

The role of currents here has been overlooked - most likely because little information has been publicly available. This is set to change thanks to a new hydrodynamic model produced by the Coastal Environmental Modelling Team at CSIRO which Tidetech will be making available for the Sydney, Melbourne and Launceston to Hobart races this year as part of a package of Grib files and analyses.
