What is priority in surfing?
B · Beginner · Priority and interference · 3 of 3The right to choose a wave. The surfer with priority may paddle for and ride any wave they want, and nobody may get in their way. They lose it as soon as they ride a wave, or paddle hard for one and miss. It then passes down the order, which is shown by coloured markers on the beach.
How it works
- What it gives: "The Surfer with priority has the unconditional right of way and can paddle for and Ride any wave they select."
- Others may still ride: an opponent can ride the same wave and be scored, provided they do not hinder the priority surfer's scoring potential.
- Lost by riding: "Wave priority is lost as soon as a Surfer rides a wave or makes a committed paddle to catch a wave and misses the wave."
- How it is given: to the surfer the priority judge believes "has reached the Primary Take Off Zone first".
- A dead heat back: if two arrive together, priority goes to the one who did not have it last.
- At the start: nobody has priority. In a two-surfer heat, once the first wave is ridden the other surfer has it.
- Larger heats: the first surfers to ride take the lowest positions, and the surfer yet to catch a wave gets first priority.
- The order: first priority is over everyone and second over all but the first. The rest follow in the same way.
- The display: coloured markers matching the vests, read from top to bottom or left to right.
- Their job to look: "It's always the responsibility of the Surfers to check for changes to the priority".
- Leaving the zone: a priority surfer who paddles outside the primary take-off zone has priority suspended until they return.
- Broken board: priority is suspended while a surfer fetches replacement equipment, and can be reinstated on their return.
The glossary has the priority entry, the priority judge, the primary take-off zone, the takeoff, the lineup and the heat.
Tricky cases
The priority surfer lets a wave go by. Can the other surfer take it?
Yes. A surfer without priority may ride any wave the priority surfer does not use.
Both surfers ride the same wave in opposite directions. Is that allowed?
Yes, provided the surfer without priority does not hinder the priority surfer's scoring potential or cross in front of them.
The priority surfer paddles for a wave, changes their mind and pulls back. Have they lost priority?
It depends on whether it was a committed paddle. A committed paddle that misses the wave loses priority, and the priority judge decides.
A surfer uses priority to take off on a poor wave only to stop their opponent having it. Is that allowed?
No. A priority surfer who takes off with no apparent intention to score, to block an opponent, will lose priority.
Why the rule exists
Without priority, every good wave would go to whoever paddled most aggressively to the inside, and heats would be decided by jostling. Priority makes it a turn-based contest. It also creates tactics: a surfer with priority can wait for the best wave of a set, while the other has to decide what to take in the meantime.
Where it differs

|---|---|---|
| Two-surfer heat | The second surfer has priority once the first has ridden | ISA, Priority System 6 |
| Three to five surfers | Positions set as each surfer rides a first wave | ISA, Priority System 7 to 9 |
| Before priority is established | The non-priority rules apply | ISA, General Priority a |
| Overlapping heats | The earlier heat's surfers have priority over the later heat's | ISA, Overlapping Heats |
