COURSE LAYING
The general principle is that the world revolves around the Start Boat.
1. Establish a waypoint at the Start Boat once it has been anchored in position
2. RO to advise course length and bearing for top and bottom bouys from Start Boat
3. Check with RO prior to laying mark and departing for next bouy.
4. Start line –set at 90° to wind off port side of start boat, distance 1.5 * boat length * number
of boats starting.
5. Gate –set at 90° to wind off startboard side of start boat at distance 75m
6. Wing mark –set at 90° to wind off port side of start boat, distance per table below:
