Some wave !

A group of surfers in Sydney claims to have broken a world record for the largest number of riders on a single wave.

Organiser Matt Grainger says 46 people caught the wave at Manly Beach this afternoon.

"It can be hard because you've got to tell everyone not worry about getting the best wave," he said.

"It's about just getting the wave and standing up, and once we got that through their heads we worked it out."

A video of the event will now be sent to Ireland for consideration in the Guinness Book of World Records.
