why were sailors from russia and france rescued while sailing from vanuatu to australia last week?

Sailors from Russia and France were rescued last week while sailing from Vanuatu to Australia because their inflatable catamaran was severely damaged by repeated shark attacks. The catamaran sustained major damage to both hulls, causing it to begin sinking in the Coral Sea about 500 miles off the Australian coast. The sailors activated a GPS-encoded emergency beacon which allowed Australian rescuers to quickly locate them and coordinate a rescue. They were picked up by a Panamanian-flagged cargo ship called Dugong Ace and were reported to be healthy and well after the rescue. The attacking sharks were identified as small cookiecutter sharks, which likely mistook the boat for a whale or dolphin carcass due to their feeding behavior. This shark attack was unusual and the exact motivation behind it remains unclear.
