The shark put a hole in a paddle and bit through one of their kayaks.

With one boat under water and the other upside down, Orr called 911.

"Help! Help! I was just on the boat with somebody," Orr tells the 911 dispatcher during the call. "We are stuck in the water and there is a shark. … He knocked me out of my kayak."

The dispatcher tells them to hang on and that help is on the way.

"We're fine but we're really scared," Orr says during the call.

"It was a f-g Great White," Orr says. "What if he comes back?"

The shark did not return and the two made it to shore unharmed after waiting in the water for 30 minutes.

"We didn't see a fin so we didn't know if it was going to come back," they said. "I was screaming [for] anybody, just anybody to help. … It was so scary."
