Rules & Disciplines
The rules that govern the race
World Sailing publishes the Racing Rules of Sailing and updates them every four years. Five core rules cover the majority of on-water situations — know them instinctively and you race with confidence.
Port gives way to Starboard
When boats are on opposite tacks, a port-tack boat shall keep clear of a starboard-tack boat. This is the most widely applied rule in racing. When in doubt, the safest action is to tack onto starboard or dip behind the starboard-tack boat.
Windward keeps clear of Leeward
When boats are on the same tack and overlapped, the windward boat shall keep clear of the leeward boat. The leeward boat may luff but must give the windward boat sufficient time and space to respond. Luffing above close-hauled when the windward boat is "mast abeam" is restricted.
Clear astern keeps clear of Clear ahead
When boats are on the same tack and not overlapped, a boat clear astern shall keep clear of a boat clear ahead. A boat is clear astern when it is behind a line abeam from the aftermost point of the leading boat.
Tacking — keep clear while tacking
After a boat passes head to wind, it shall keep clear of other boats until it is on a close-hauled course. During this transition period, it has no right of way and must avoid impeding boats on a tack.
Mark-Room at the Zone
The "zone" is the area within three hull lengths of a mark. When a boat is overlapped inside at the zone, the outside boat must give mark-room — sufficient room to sail to the mark and round it in a seamanlike manner. The overlap must exist before the leading boat enters the zone.
Room to Tack at an Obstruction
When a close-hauled boat cannot tack without colliding with an obstruction, it may hail "water" to a windward boat. The windward boat must either tack immediately or reply "you tack." Refusing to comply is a breach of the rules.
Penalties and Protest
On-Water Penalties
When a boat breaks a right-of-way rule, the standard penalty is to complete two full 360-degree circles — the "two-turns penalty." Taking the penalty voluntarily and promptly is nearly always faster than defending a protest hearing.
Touching a mark requires one 360-degree circle. Some regattas use alternative penalty systems — always check the Sailing Instructions before racing.
Protest Hearings
A boat that believes she has been wronged may file a written protest within the time limit specified in the Sailing Instructions. A protest committee of at least three qualified judges hears the facts from both parties and witnesses.
The potential outcome ranges from dismissal of the protest to disqualification from the relevant race. Gross misconduct can result in exclusion from the entire regatta.
Sailing disciplines
Fleet Racing
Multiple boats race simultaneously around a fixed course. Results are determined by finishing order across a series of races.
Match Racing
Two boats race head-to-head. Tactics are intense and rights-of-way rules are exploited aggressively on the start line and at marks.
Team Racing
Two teams of three boats race simultaneously. Finishing positions determine a team score — cooperation between team members is essential.
Offshore Racing
Long-distance races from harbour to harbour or around ocean waypoints. Handicap systems allow different boat types to compete fairly.
Dinghy Racing
Contested in one-design or development-class small boats. Sailing skill and tactical judgement are decisive — there is nowhere to hide.
Foiling
Modern high-performance classes use hydrofoils to lift the hull clear of the water, reaching speeds several times the wind strength.
