A teenage girl was admitted to hospital ,suffering from hypothermia and another with a leg injury, the National Sea Rescue Institute (NSRI) said.
“A 17-year-old female was transported to hospital suffering a leg injury and a 16-year-old female was transported to hospital suffering hypothermia,” said spokesman Craig Lambinon.
Both girls were from the Knysna sailing team taking part in the 2014 Lipton Cup Challenge.
