In every regatta, clarity and precision are essential. When race officials or mark layers need to change the next leg of the course, competitors must instantly understand the new instructions. That’s why the Racing Rules of Sailing (RRS) Rule 33 sets clear requirements.
The Rule - RRS 33
According to the World Sailing Racing Rules of Sailing 2021–2024:
Rule 33 – Changing the Next Leg of the Course
“The signal shall be the display of flag C with repetitive sounds and may be accompanied by the compass bearing of the next leg, a green triangular flag or board for a change to starboard, or a red rectangular flag or board for a change to port.”

Why Sound Matters in Rule 33
Wind and waves can drown out a weak signal. A whistle can be missed, and electronic devices may fail at the critical moment. To keep races fair and professional, you need a tool designed for instant recognition, durability, and reliability.
