Who has right of way on a wave when there is no priority?
I · Intermediate · Priority and interference · 3 of 4The surfer on the inside, meaning nearest the part of the wave that is breaking. That surfer has "unconditional right of way for the entire duration of that ride". It applies before priority is set and in heats run without it. Being first to stand does not decide it, except where two separate peaks meet.
How it works
- The rule: "the surfer deemed to have the inside position for a wave has unconditional right of way for the entire duration of that ride".
- Not first to feet: judges decide the inside position "never on which Surfer is first to their feet", except with multiple peaks.
- Point break: with one direction available, the inside surfer has the wave.
- One peak, two directions: right of way goes to "the first surfer who makes a definite turn in their chosen direction".
- Splitting the peak: a second surfer may go the other way on the same wave without penalty, if they do not cross the first surfer's path.
- Neither commits: if they collide without either making a definite turn, both are penalised.
- Two peaks that meet: the surfer whose hands leave the board first has right of way, and the other must cut back or kick out.
- Both up together: if both give way, no penalty. If they collide, the one showing aggression is penalised, or both.
- Snaking: a surfer who takes off behind another who has established right of way does not gain it, and may be penalised for causing them to pull out.
- The penalty: in these situations, interference penalty 1.
The glossary has the right of way entry, the snaking entry, the peak, the point break, the reef break, the takeoff and the shoulder.
Tricky cases
One surfer stands up first, but the other is nearer the breaking part. Whose wave is it?
The inside surfer's. Standing first does not decide right of way, except where two separate peaks meet.
Two surfers take off on the same peak, one going left and one right. Is that an interference?
No, as long as neither crosses the other's path or hinders them.
A surfer paddles round behind another who is already taking off, to get the inside. Do they now have right of way?
No. That is snaking. The original surfer keeps the wave, and the second may be penalised if they cause them to pull out or lose it.
Who decides which surfer is on the inside?
Each judge, based on whether the wave is a better right or left. An interference is called only if a majority of the panel marks it.
Why the rule exists
This is the etiquette of every surf break written into rules: the surfer closest to the breaking part of the wave has the longest and most difficult ride available, so the wave is theirs. Dropping in on them from further along the wave is dangerous as well as unfair, since two boards end up on one line.
