Competitive terms
Interference penalties
Penalty 1 halves the interfering surfer's second-highest ride, Penalty 2 scores it as zero, and Penalty 3 scores the highest ride as zero. Disqualification removes the surfer from the heat. In ISA World Surfing Games and Olympic-related events only, interfering with a potential scoring ride in the last five minutes brings Penalty 3, and intentional interference then disqualifies.
The ruleWhat is the penalty for an interference in surfing?Priority judge
The official who calls priority, using a colour display matching the surfers' jerseys, and may consult the judging panel on close calls. A surfer who gets an interference penalty loses priority, and the Priority Judge sets the new order.
Head judge
The judge who supervises the panel for a heat, keeps an equal wave count among the judges, and tries to tell a surfer who was interfered with that they have an extra wave.
Snaking
Taking off behind a surfer who already has right of way and causing them to pull out or lose the wave. The second surfer may be given an interference penalty even though they are behind. The surfer with right of way is not penalised for being in front.
Paddling interference
A surfer paddling for the same wave hindering the surfer with inside position, by contact or blocking, or by clearly causing a section to break down in front of them. A collision with a surfer paddling out is judged by safety and the effort made to avoid it.
Primary take-off zone
The area in the line-up where priority applies. Priority is suspended for a surfer who is washed out of it by a set or who goes to replace damaged equipment, and can be reinstated when they return.
Heat tie-break
Ties are broken by the best single score in the heat, then the third best, and so on; then by the average of all five judges on the two best scores; and, if still tied, by a re-surf.
Re-surf
A heat surfed again to break a tie that nothing else resolves. If both tied surfers are advancing, seeding or the earlier round's scores decide instead, and if both are losing they share the place.
Competition terms
Championship tour
The top level professional surfing circuit, featuring events at various locations worldwide.
Wave selection
The strategic choice of which waves to ride during a heat, since only the best scoring waves count.
Right of way
Without priority, the surfer with the inside position has unconditional right of way for the whole ride. On a point break that is the inside surfer. With a single peak and both directions available, it goes to the first surfer to make a definite turn. With two peaks, it goes to the surfer whose hands leave the board first.
Wave and technique terms
Peak
The point on a wave where it first begins to break, often the strongest and most rideable section.
Shoulder
The unbroken, gently sloped section of a wave beyond the breaking peak.
Closeout
A wave that breaks all at once along its length rather than peeling in one direction, making it hard to ride.
Reef break
A wave that breaks over a rocky or coral reef rather than a sandy bottom.
Point break
A wave that breaks along a point and can be ridden in only one direction. In a contest on a point break, the surfer on the inside has unconditional right of way for the whole wave.
Snap
A sharp, fast turn off the top of the wave, often used to redirect back toward the breaking section.
Equipment terms
Fins
Attachments on the bottom of the board that provide grip and control during turns.
Rocker
The curve of a surfboard from nose to tail, affecting how it turns and how it handles different wave sizes.
Leash
A cord attaching the surfer's ankle to the board, preventing it from washing away after a fall.
Rail
The edge of the surfboard, whose shape affects how the board grips the wave during turns.
