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.

The last 10 miles of the Rolex Sydney to Hobart Yacht Race (from Iron Pot to the finish) has often been the graveyard of ambitions for many competitors. With the finish line in sight, fickle winds and tides make it a tactician’s nightmare, potentially wrecking an otherwise well-sailed race.
