Starting Procedures

The starting procedure is the most critical moment of every race. Within a few minutes, it is decided whether a race begins fairly, whether the fleet is positioned safely, and whether protests are already looming before the first mark rounding. For the race committee (RC), a professional starting procedure means precise planning, clear communication, and consistent rule enforcement. For sailors, it is the starting point of every tactic. This guide explains how organizers define, conduct, and confidently respond to disruptions in starting procedures.

Why Starting Procedures Are More Than a Signal

A regatta start is not a spontaneous event. It is the result of a chain of organizational decisions: Where is the Starting Line? Which Start Recall System rule applies? How long is the preparation time? Which boat classes start together or separately? All these provisions are set out in the Sailing Instructions (SI) and must be communicated before the first race day.

A well-organized starting procedure ensures:

  • Fairness – all boats have the same information and the same time
  • Safety – sufficient distance between fleet, RC, and mark boats
  • Efficiency – fewer restart attempts and shorter waiting times
  • Legal certainty – traceable decisions on OCS Boat, recall, and protest

Those familiar with the basics of regatta organization will find the broader context in Planning and Running a Regatta. The technical implementation of the start line is closely linked to Courses and Markings and the Committee Boat.

Important: Starting procedures are defined in the SI and may deviate from the standard rules of the Racing Rules of Sailing (RRS). The RC may not change rules during an ongoing start – adjustments apply only to the next start attempt.

The Start Line – Heart of Every Procedure

The start line connects two fixed points: typically the committee boat at the leeward end and a pin-end boat or buoy at the windward end. The line must be positioned so that the entire fleet can maneuver safely at the expected wind strength.

Criteria for Line Position

  1. Line length: Rule of thumb: boat length times number of starters plus 20–30 percent buffer. For 30 ILCA boats at 4.2 m each, that yields at least 160 m of line.
  2. Bias: The windward end is often more advantageous (Favored Start End). The RC can set the line at an angle to balance unfair end advantages.
  3. Distance to the first mark: Too short leads to mass collisions after the start; too long allows excessive maneuvering and increases OCS risk.
  4. Safety zone: Maintain minimum distance from land, swimming areas, shipping lanes, and spectator boats.

Tip: Set a test line before the first start of the day and document the exact coordinates with GPS. In case of wind shifts, the RC can deliberately move the line for later starts – the new position must be communicated by flag and, if necessary, by radio.

Standard Start Sequence in Fleet Racing

The classic Olympic start sequence is established worldwide and forms the basis of almost all inshore regattas. It is based on the Flag P flag (P) as the preparatory flag and a countdown structure using sound signals.

Olympic Start Sequence

−5 Min
Warning signal – class flag hoisted, one sound signal
−4 Min
Preparatory signal – flag P hoisted, one sound signal
−1 Min
One-minute signal – flag P lowered, one sound signal
0 Min
Start signal – P lowered, class flag remains, start line open
Recall
Recall if OCS – I, U, or black flag signal
End
Line closed – all boats passed or recall period expired

Sequence in Detail

  1. Warning signal (5 minutes before start): Class flag is hoisted, one sound signal sounds. Boats may not yet cross the start line.
  2. Preparatory signal (4 minutes before start): Flag P is hoisted, one sound signal. The start sequence is running – boats position themselves.
  3. One-minute signal (1 minute before start): Flag P is lowered, one sound signal. Final phase before the start.
  4. Start signal (0 minutes): P is lowered, class flag remains, one sound signal. The start line is open.
  5. After the start: The RC observes OCS boats, sets recall signals if necessary, and closes the start line once all boats have passed the line or the recall period has expired.

The meaning of individual flags and signals is described in detail in Start Signals and Flags.

Olympic vs. Match Race vs. Line Start

Olympic / Fleet Start

Fleet size: many boats simultaneously

RC effort: high

OCS risk: high

Match Race Start

Fleet size: 2 boats

RC effort: medium

OCS risk: low

Line Start

Fleet size: many sequentially

RC effort: low

OCS risk: very low

Recall Options and Their Consequences

Recall rules must be defined in the SI before the regatta. They determine what happens when boats cross the line before the start signal (On Course Side, OCS).

Recall Type
Flag
Consequence for Early Starters
RC Effort
Individual Recall
I (Code Flag I)
Affected boats must sail back and restart
Medium – individual identification required
General Recall
First Substitute (X)
Entire fleet restarts
Low – but time-intensive
U-Flag Rule
U (Code Flag U)
Early starters receive disqualification (UFD)
Low – deterrent effect
Black Flag
Black Flag
Early starters receive disqualification (BFD)
Low – for experienced fleets

In-depth articles: Individual Recall and General Recall as well as Black Flag and U-Flag. The status abbreviations OCS, BFD, and UFD are explained in DNF, DNS, DSQ and OCS.

At black flag and U-flag starts, the RC must immediately note the affected sail numbers. Incorrect documentation inevitably leads to protests and jury hearings.

Race Committee Tasks at the Start

The RC consists of several people with clearly assigned roles. At large events, this is often five to eight people plus mark boat crews.

Core Tasks Before the Start

  • PRO (Principal Race Officer): Overall responsibility, decisions on start, recall, and abandonment
  • Starter: Gives sound signals and monitors the countdown clock
  • Flag officer: Hoists and lowers flags in sync with the starter
  • Line observer: Identifies OCS boats, often with binoculars and sail number list
  • Timekeeper: Documents start time and recall events
  • Safety boat: Ready for man overboard, collisions, or technical assistance

The organizational context of the RC can be found in Race Committee and PRO.

Avoiding Common Mistakes

  1. Unclear start line: Drifting pin-end buoys or an unsecured RC boat provoke protests.
  2. Delayed signals: Deviations from the countdown undermine fleet confidence.
  3. Missing OCS documentation: Sail numbers must be noted immediately.
  4. Too short recall period: Boats need time to sail back and restart.
  5. Communication gaps: Line shifts must be visible to all boats.

Checklist: Starting Procedure for the RC

Before each start, the RC should work through these points:

  • Class flag and recall flags ready
  • Sound signal device tested (horn, gong, or cannon)
  • Start line fixed with GPS, pin-end buoy secured
  • Sail number list of entered boats available
  • Clock synchronized (ideally with official regatta time)
  • Safety boat positioned near the start
  • Recall rule confirmed per SI (I, U, black flag, or general recall)
  • Wind and sea state checked for start clearance
  • Communication between RC members clarified (hand signals, radio)
  • Protest committee informed of start time

Special Start Formats

Handicap, Multi-Class, and Match Race Starts

In ORC and IRC regattas, boats start at staggered times according to handicap – timing begins at the respective start signal. Multi-class starts require clear flag assignments in the SI or sequential starts with breaks. Match race and team race starts use compact courses with their own rule sets; the RC watches for Rule 10 situations and coordinates multiple RC boats on parallel courses.

Start Preparation on Race Day

08:00
Morning briefing – course, recall rules, weather
09:00
Set line – position committee boat and pin end
09:30
Test signal – check sound signal device and flags
10:00
First start – warning signal, countdown begins
10:05
Recall or race underway – OCS control or fleet on course
11:30
Second start – next class or second race

Sailor Perspective: What the RC Should Know

From the participants' point of view, start quality depends on transparency. Sailors expect:

  • Visible flags even in backlight and rough seas
  • Audible signals – in winds from 15 knots, a horn is often not enough for the entire fleet
  • Consistent sequences – no deviations from the countdown structure described in the SI
  • Quick recall communication – I flag within seconds of OCS detection

The tactical side of the start – favored end, port-starboard decisions, timing – is covered in Start Tactics. Technical maneuvers such as timed approach to the line are explained in Starting Maneuvers.

Disruptions and Exceptional Situations

Postponement Before the Start

If a start is postponed, the RC hoists the AP flag (Answering Pennant) and gives one sound signal. All boats must leave the start line immediately. Only when AP is lowered and a new warning signal sounds does a new start sequence begin.

General Recall – When and Why

A general recall makes sense when:

  • more than one third of the fleet is OCS
  • the start line has shifted during the sequence
  • a safety incident ties up the RC's attention
  • the wind shifts fundamentally and the line must be reset

After a general recall, there is typically a short pause (1–2 minutes), then a new warning signal.

Abandonment After the Start

If the RC must declare a start invalid after the start signal (e.g., due to the wrong flag), the fleet is recalled by flag and sound signal. All boats return to the start area. This situation is rare, but the RC must describe the procedure in the SI.
