Race Committee and PRO

The Race Committee (RC) is the operational heart of every regatta on the water. While crews trim, tactically manoeuvre and fight for positions, the RC under the leadership of the Principal Race Officer (PRO) ensures that starts are fair, courses are set correctly and results are recorded reliably. Anyone who understands the work of the RC not only sails more rule-compliant – they can better assess start decisions, file more substantiated protests and build professional events as an organizer.

This guide deepens the structure, procedures and responsibilities of the Race Committee – complementing the overview under Regatta Management and Race Officials.

What is the Race Committee?

The Race Committee is the body responsible for the sporting conduct of the races in accordance with the Racing Rules of Sailing (RRS) Part 3 – Conduct of a Race. It is not a protest jury: the RC decides on starts, course management, timing and flag communication, but not on rule disputes between boats (that is the task of the jury, see Protest Procedure).

The specific requirements for each event are set out in the Notice of Race and the Sailing Instructions – documented in detail under Notice of Race and Sailing Instructions. The RC implements these instructions on the water and may only deviate from the SI where the rules expressly permit (e.g. postponement in unsuitable conditions).

Core Tasks of the Race Committee

1. Course planning: Selection of course format (windward-leeward, trapezoid, slalom) depending on wind, waves and fleet
2. Start management: Conducting the start sequence, monitoring the start line, identifying OCS boats
3. Mark management: Setting, monitoring and, if necessary, moving rounding and gate marks
4. Timing: Recording start, rounding and finish times; reporting to the results service
5. Communication: Signals via flags, horn and radio; announcing changes and abandonments
6. Safety monitoring: Observing weather development, visibility and rescue readiness

Hierarchy of the Race Committee on the Water

The Principal Race Officer (PRO)

The Principal Race Officer is the lead race official of the Race Committee. They bear overall responsibility for all decisions on the water and are the first point of contact for organizational questions during the race – but not for protest hearings.

Qualifications and Experience

A PRO should have solid knowledge of the RRS, ideally through a World Sailing or national federation certificate as a race officer. Practical experience on various boat sizes and in changing conditions is crucial: an experienced PRO recognizes early when a postponement or abandonment is necessary, instead of forcing a race in unsafe conditions.

Typical PRO competencies:

• Confident start sequence even with large fleets (50+ boats)
• Clear radio communication with mark boats and regatta office
• Quick course adjustment during wind shifts or lulls
• De-escalation of conflicts on the water (without intervening in jury decisions)
• Documentation of incidents for subsequent protest procedures

Structure of a Race Committee

The size and structure of the RC depends on the event. A club dinghy regatta with 20 boats requires a lean team; an international championship with multiple classes and parallel courses requires a significantly larger setup.

Typical Daily Schedule of the Race Committee

A regatta day follows a structured schedule that begins the evening before or early in the morning:

1. Weather briefing: PRO and event management evaluate weather forecast, radar and local observations
2. Course briefing: Setting the course, mark positions and start procedure – often in the morning briefing with participants
3. Course setup: Mark boats head out, committee boat positions at the start line
4. Warning signal and preparation: PRO gives the agreed advance warning time (typically 5–10 minutes before start)
5. Start sequence: Countdown with flags and horn according to SI
6. Race monitoring: Observing the fleet, adjusting marks if necessary
7. Finish: Last boat crosses the finish line, safety vessels remain on duty
8. Results reporting: Times to results service, announcement of provisional results
9. Debrief: RC debriefing, documentation of incidents for the jury

Start Sequence and Signals

The start sequence is the most visible task of the PRO. It follows the signals defined in the SI – usually the Olympic start procedure with 5-4-1-0-start or variants with U flag and black flag.

Standard Olympic Start (Simplified)

• 5 minutes before start: Class or regatta flag up, one sound
• 4 minutes before start: P flag (preparatory) up, one sound
• 1 minute before start: P flag down, one sound
• Start: Class flag down, one long sound

For Individual Recall and General Recall, the RC responds with the prescribed signals: X flag for individual recall, first substitute for general recall. The PRO must set these signals clearly and without delay – any ambiguity leads to protests and frustration in the fleet.

Committee Boat and Equipment

The committee boat is the command centre of the RC. At international events it is often a dedicated motorboat with an elevated aft platform; at club regattas a moored boat or a RIB with good visibility of the start line is often sufficient.

Mandatory equipment on the committee boat:

• Complete flag set according to RRS Appendix G
• Horn signalling device (air or electric) with sufficient volume
• Radio sets for all mark boats and safety vessels
• GPS and compass for course planning
• Binoculars and, if applicable, video camera for OCS documentation
• Weather notes, SI printout, start lists
• First aid kit and life jackets for the crew

Committee Boat Inspection Before the First Start

• Flag set complete and legible
• Horn functional
• Radio on correct frequency
• GPS coordinates of start line saved
• SI printout on board
• Start lists up to date
• Life jackets for RC crew
• View of entire start line and first windward mark zone

Communication with Participants

Clear communication is half the battle for a smooth race. The RC communicates via three channels:

Flags and horn: Primary channel during the race. All participants must know and watch the signals – even if radio reception is possible on board.

Radio (VHF): For mark boats, safety vessels and occasional announcements to the fleet. The frequency is stated in the SI. The PRO speaks briefly and repeatably – long announcements over radio are unusual during a race.

Notice board and online portal: Changes to SI, course adjustments and results are published on the notice board and increasingly via regatta apps. The RC reports incidents and protest-relevant observations to the jury in writing.

Decisions in Difficult Conditions

The PRO bears responsibility for safe and fair conditions. The most difficult decisions concern:

Postponement (AP Signal)

When wind, waves, visibility or current prevent a fair race, the PRO hoists the Answering Pennant (AP) and postpones the start. Multiple AP signals in succession are possible. Details on signals and procedure: AP, Postponement and Abandonment.

Abandonment During the Race

In case of sudden thunderstorm front, fog or accident, the PRO sets abandonment signals (N or A flag plus three sounds). The scoring of the abandoned race is governed by the SI and the scoring system.

Course Change During the Race

The PRO may change the course if this is provided for in the SI (e.g. "PRO may move marks"). The change must be communicated to all boats – by radio, flag or safety boat. An uncommunicated mark move is a common reason for redress requests.

RC and Protest Jury: Clear Separation

The Race Committee and the protest jury work hand in hand, but are strictly separated:

• The RC observes and documents incidents, but does not decide on protests
• The jury conducts hearings and renders decisions according to the Racing Rules of Sailing
• The PRO may be called as a witness in a protest hearing
• RC members who observed an incident provide written reports for the jury

Best Practices for Organizers and PROs

For Organizers

• Assemble the RC team at least six weeks before the event
• Organize an RC briefing the evening before with SI walkthrough
• Ensure sufficient mark boats and radios – bottlenecks cost race days
• Plan a backup PRO in case of illness or severe weather

For Aspiring PROs

• Start as ARO or mark boat crew at club regattas
• Complete race officer courses with your national federation or World Sailing
• Observe experienced PROs at national events as shadow officer
• Study protest decisions – they show where RC documentation was lacking

For Sailors

• Constantly watch the committee boat and its signals
• Know the SI for your event – especially start procedure and protest time limits
• React immediately to recall signals; hesitation costs positions
• Report observations promptly to your coach or protest representative
