A pod of orcas attacked a yacht in the Strait of Gibraltar, ripping off both of its rudders.
The sailor said it felt as though the orcas were throwing the yacht around "like a rag doll."
There have been 20 incidents of orca attacks in the Strait of Gibraltar in the past month alone.
He also said the killer whales moved in a way that seemed "choreographed, almost, like synchronized swimming," according to the radio broadcast.
Insider's Isobel Van Hagen previously reported on an incident last month in which a pod of orcas rammed a yacht in the Strait of Gibraltar.
