Basic Rules and Right of Way

The Racing Rules of Sailing (RRS) form the foundation of every regatta. At their core, two things matter: fair competition and safe manoeuvring in close quarters. Those who master the basic rules and the right-of-way system make better tactical decisions in a race, avoid penalties, and protect crew and equipment.

This guide explains the most important rules from Part 2 of the RRS – from fundamental obligations to classic encounter situations on the wind, on a reach, and when overtaking.

What the Racing Rules of Sailing govern

World Sailing publishes the RRS in regular cycles. For regatta sailors, Part 1 (Fundamentals), Part 2 (When Boats Meet – right of way), and Part 3 (Conduct of a Race) are especially relevant. The basic rules (Rules 10–23 in Part 2) determine which boat must give way – regardless of boat class.

Structure of RRS Part 2

The fundamental basic rules (Rules 10–13)

Before analysing individual encounter situations, four rules must be understood. They form the basis for almost every protest and tactical discussion.

Rule 10: Port before starboard

A boat on port (wind from port) must give way to a boat on starboard (wind from starboard). This is the best-known rule and applies as long as no more specific rule takes effect.

Practical example: Two boats are on a collision course. Boat A has the wind from port, Boat B from starboard. Boat A must keep clear in good time or tack so that B can continue on course.

Rule 11: Windward before leeward

When two boats are sailing on the same tack, the windward boat must give way to the leeward boat. The windward boat must not squeeze the leeward boat.

Typical situation: Both boats are sailing close-hauled on the same tack. The windward boat pushes too aggressively – leeward calls “Protest” and is often in the right.

Rule 12: Overtaking boat must give way

A boat approaching another from astern must give way. “Astern” means: any line drawn across the hull of the overtaken boat and perpendicular to the centreline lies astern of that point.

This applies even if the overtaking boat seemingly has “more wind” or is sailing faster. Speed does not change the obligation.

Rule 13: Tacking and gybing

A boat that is tacking or gybing must give way to all other boats that are not tacking or gybing. The rule protects boats that are already on a stable course.

Right of way at a glance: Who must give way to whom?

The following table summarises the most common encounter situations. More specific rules (e.g. Rule 18 at marks) can override this basic logic.

Close-hauled vs. reach

Sailing close-hauled: windward, leeward and starboard

Close-hauled, the right-of-way system is at its densest. Here, centimetres often decide space on the layline or at the start line.

Starboard-port encounters

When two boats approach each other on opposite tacks close-hauled, Rule 10 applies: port gives way to starboard. The starboard boat must be able to hold its course – it is not obliged to give way.

Tactical tip: A starboard boat can deliberately signal “holding course” to force a port boat to give way. However, aggressive pushing beyond the limit can violate Rule 14 (Avoiding contact) or Rule 16 (Changing course).

Windward-leeward on the same tack

When two boats sail parallel on the same tack, leeward has right of way. The windward boat must not restrict leeward before it is clearly ahead and leeward has sufficient room.

Practice at the windward mark: The windward boat often tries to “cover” leeward – but without Rule 18 protection at the mark, it must give leeward room to sail.

Reach and different tacks

On a reach, the same basic rules apply, but situations often appear clearer because the angles are wider. Rule 10 remains central: whoever is on port gives way to starboard.

It becomes especially critical when approaching a mark from different directions. Then Rule 18 (Mark-room) and the sailing instructions of the regatta also apply. Details can be found in the article on Rule 18 and mark roundings.

Overtaking: Rule 12 in practice

Overtaking situations occur on all legs – close-hauled along the layline, on a reach on the reach leg, or when approaching the finish.

1. Recognise: Is your boat astern of the transverse line through the hull of the other boat?
2. Obligation: The overtaking boat must give way – even if it is faster and sailing “correctly” on the layline.
3. Give room: The overtaken boat must be able to hold its course; it must not deliberately block the overtaking boat (Rule 17 – On the Same Tack; Proper Course).

Executing an overtaking manoeuvre correctly

Obligations beyond simply giving way

Right of way is not everything. Three rules supplement the basic logic and are often decisive in protests.

Rule 14: Avoiding contact

Boats must avoid contact when it is reasonably possible – including the boat with right of way. Anyone who causes contact although they could have given way risks a penalty.

Rule 15: Acquire Right of Way

Whoever acquires right of way (e.g. by tacking from port to starboard) must initially give the other boat room and time to give way. Immediate pressure after the manoeuvre is forbidden.

Rule 16: Changing Course

A boat with right of way must not change course if another boat would then be forced to react immediately to avoid contact. This mainly affects windward boats that squeeze leeward.

Checklist: Right of way before and during the race

Use this checklist in training and on the water:

• Can I name the tack (starboard/port) of all relevant boats?
• Do I know whether I am windward or leeward – and which rule that triggers?
• Do I check for clear space before every tack or gybe manoeuvre (Rule 13)?
• As a starboard boat, do I hold course without violating Rule 16?
• As a boat that has just acquired right of way, do I give room (Rule 15)?
• Do I avoid contact even when I am in the right (Rule 14)?
• Does the crew know the calls “Starboard!”, “Protest!” and “Room at the mark!”?

Common mistakes and how to avoid them

1. Reading rules only from your own right-of-way perspective. Even boats with right of way have obligations (Rule 14, 16).
2. Tacking without checking. Rule 13 protects others – before tacking, check starboard, leeward and astern.
3. Confusing Rule 18 with Rule 11. At marks, special rules for “room” apply – see the Rule 18 article.

Frequently asked questions

Right of way and regatta tactics

Rule knowledge is a tactical weapon: those who know when an opponent must give way can apply pressure – without violating Rule 16 or 14. Typical moves include holding starboard course close-hauled, covering leeward, planned overtaking (Rule 12), and start-line tactics in the context of Rule 11.

Experienced teams discuss not only the wind in the morning briefing, but also typical encounter points on the course.

Connection with penalties and protests

Violations of right of way do not automatically lead to disqualification. In most cases:

• The rule breaker takes a penalty (e.g. one-turn or 720° turn, depending on sailing instructions).
• Without a penalty, or in serious violations, a protest before the protest committee can be decisive.

Those who master the basic rules recognise early whether a penalty is necessary or a protest makes sense – and avoid unnecessary point losses through sloppy manoeuvres.
