Main rules

Helm privileges #

Rule 10 - Starboard tack priority #

When two sailboats pass each other while sailing in opposite directions, the one on starboard tack (receiving the wind from starboard) has priority. The sailboat on the port tack must then maneuver so as not to interfere with the other.

Rule 11 - Leeward Priority #

When two sailboats are under the same tack and their trajectories converge, the priority belongs to the leeward sailboat. The windward sailboat must not generate the trajectory of the leeward sailboat or force it to maneuver.

On the other hand, the leeward sailboat may not interfere with the windward sailboat beyond the upwind.

Rule 12 - Catch-up priority #

When a sailboat catches up with another, the right of way belongs to the overtaken sailboat.

The overtaking sailboat must not interfere with the sailboat in front of it.

Rule 18 - Priority when passing the buoy #

When passing a mark, the sailboat with priority is the one furthest inside the turn. Other sailboats will have to move aside if they interfere with the priority sailboat.

• must be exonerated if it violates this rule and the contact causes no damage or injury.

Rule 15 - Acquiring the right of way #

A yacht when acquiring the right of way must allow time and space for the other to keep clear. Unless it acquires the right of way due to an action on its part.
