Not exactly. Could be 3:

- windward/leeward courses
- offset mark (minimum 70° to the wind direction) to be rounded after the windward mark
- gate at the leeward mark
- 2 or 3 rounds, target time for the first boat to finish : 60 minutes. Longer or shorter actual duration for a race will not be ground for redress.
