SYDNEY - HOBART CURRENT PREDICTIONS

Each year since 2000, Local Knowledge has provided current data in digital format for the Sydney-Hobart Race. These current predictions support Local Knowledge Tactical Software, and are also available in grib format for display and routing computations in all brands of third-party software (see the examples below).

Other programs display current predictions by showing values at the defined points in the current grib file. LK uses proprietary methods to build hydrodyamic current models which, in effect, put more points in regions where current varies more sharply. LK has a current display option (see below) which shows current vectors at a representative grid of points. The display uses the same number of points regardless of the scale, so the more you zoom in, the greater the detail. Unlike other programs, however, the display grid is not the same as the model resolution. LK programs allow the user to add current display points anywhere desired, since the model computes continuously point to point.
