Surfer A is nearer the shoulder and has right of way. B must give way to A. If B does catch the wave he/she is "dropping-in" on surfer A.

Surfer A has right of way. B must give way to A who has already caught the wave.

Surfer B is not entitled to catch the wave that is already caught and being ridden by surfer A.

Surfer A, having already caught the wave, has right of way over surfer B.

Surfer B’s progress toward the unbroken wall has halted. Surfer A is then entitled to take-off.

Surfer A, riding in or in front of the white water toward the unbroken shoulder has right of way. Surfer B must not take-off.

Surfer B, attempting to take-off in a broken section of a wave, has no entitlement to the shoulder occupied by surfer A.

Surfer A wipes out. Surfer B may then catch the wave.

Surfer A has right of way on the right hand shoulder while surfer B has right of way on the left hand shoulder.

Where there is a clearly rideable left and right shoulder, surfer B is not entitled to cross under the peak to the shoulder already occupied by surfer A.

Surfer A may cross under the peak to the unoccupied right-hander shoulder. In doing so the left hand shoulder will become available for other surfers to catch.

Both surfers are entitled to take-off and ride the unbroken wave section but neither has right of way over the other one or both must pull off the wave before a collision occurs.

Surfer A, riding the wave, must avoid surfer B who is either stationary or paddling out. This is true except in competitions, when A has priority. It is common practice for surfer B, if he/she has time, to paddle towards the white water to avoid surfer A.
