A group of South African surfers say they have broken the record for the number of people riding a single wave.
Organisers say that 73 surfers managed to stay upright for five seconds, beating the previous best of 44.
The event was organised to raise money for spotters who watch the sea to raise the alarm when sharks are seen on Muizenberg beach near Cape Town.
A lifeguard recently had his foot bitten off by a great white shark in the area.
"We have broken the world record," said organiser Dene Botha jubilantly.
"We don't know exactly by how many, but we have a record."
The record still has to be confirmed by the Guinness Book of Records.
