JJ Giltinan 18ft Skiffs: Big rigs for Day 1 - PredictWind
Sat, 16 Feb 2013
Moderate winds from a southerly direction are forecast for the first race of the 64th JJ Giltinan 18ft Skiff Championship being sailed on Sydney Harbour
PredictWind is showing a a breeze expected to average 10-13kts around race start time of 4.00pm, slowly easing to 8-10kts a couple of hours later. Gusts will be above this average strength.
There is no certainty as to the direction of the breeze, which is expected to be just south of east around noon, however the two feeds on direction developed by PredictWind as the basis of its forecasts sow the breeze moving in opposite directions after that time. At this stage one feed shows the stronger breeze clocking around to the SE as it eases during the day. The other feed shows a lighter breeze shifting north as it also eases later in the day.
Bottom line for crews is that there is some certainty for rig selection (big rigs a certainty) and the options for direction will have to be made on the water once the direction becomes evident and the expected trend can then be determined.
This prognosis has been based on a reference point in the centre of Sydney Harbour, and will obviously vary on the edges of the course
