Recommended courses
Start line: Red
Why this recommendation?
The 192 degree true forecast converts to approximately 193 degrees magnetic and uses the nearest 15 degree matrix column: 195 degrees.
Very short selected after applying the race-day sea-state and safety checks to the 11.3 kt mean wind and 20.9 kt gust forecast.
Operational adjustment: Modelled waves of 1.8 m trigger a very-short course.
Wind-based selection; shorten for poor visibility, rough sea or other race-management concerns.
