OOD course list
Recommended courses
Start line: G/W
Why this recommendation?
The 153 degree true forecast converts to approximately 154 degrees magnetic and uses the nearest 15 degree matrix column: 150 degrees.
Very short selected after applying the race-day sea-state and safety checks to the 13.8 kt mean wind and 21.7 kt gust forecast.
Operational adjustment: Modelled waves of 1.3 m trigger a very-short course.
Wind-based selection; shorten for poor visibility, rough sea or other race-management concerns.

Why: The 2026 selector assigns Course 1Y to Oppy 1 & 2 for this course length and magnetic-bearing column. Its route refers to page 27, which was not included in the supplied scan.
Why: The Very short matrix at 150 degrees magnetic assigns Course 3 to Feva. The normal published mark sequence applies. The route starts at the midpoint of the G/W line, uses Green Bay as its Bay Mark and finishes at the midpoint of the white line.
Why: The Very short matrix at 150 degrees magnetic assigns Course 12 to Slow Misc. The normal published mark sequence applies. The route starts at the midpoint of the G/W line, uses Outer Bay as its Bay Mark and finishes at the midpoint of the white line.

Why: The Very short matrix at 150 degrees magnetic assigns Course 14R to 1/2 Rater. The R suffix selects the published reverse mark sequence. The route starts at the midpoint of the G/W line, uses Inner Bay as its Bay Mark and finishes at the midpoint of the white line.
The blue arrow points downwind and its label states where the wind comes from. Each coloured route begins at the midpoint of its recommended start line, follows the published mark sequence and finishes on the white line. The OOD's instructions remain authoritative.
