Several small sharks about the size of a cigar are to blame for sinking a 29-foot catamaran this week sparking a dramatic night-time at-sea rescue, the vessel's survivors said.

Maritime authorities in Australia recued three sailors early Wednesday after officials said sharks attacked and sunk an inflatable catamaran in the Coral Sea.

The sailing party, two Russians and one French national, were safely pulled from the ocean while on their way to the northern Australian city of Cairnsfrom Vanuatu in the South Pacific, the Australian Maritime Safety Authority reported.

One of the rescued sailors, Russian Evgeny Kovalevsky, told The Guardian cookiecutter sharks are responsible for sinking the sailboat.

“[We were] not scared about our life. We [were] scared about the finishing of expedition,” he told the outlet, adding it was not the first time he'd come under attack by that species of shark.

Kovalevsky told the outlet he encountered them more than a decade ago in the Atlantic Ocean while, ironically, also on an inflatable vessel.

What is a cookiecutter shark?

The cookiecutter, according to the Shark Research Institute, measures an average of 12-19 inches in length and has thick lips and "razor sharp teeth" used to attach itself to prey leaving behind a crater-size wound.

Cookiecutter sharks generally live the oceanic ‘twilight zone’ in depths to 3,300 feet (1,000 meters) and eat fish, squid, and crustaceans. They usually only surface from the deep at night, the research institute said.

Unlike other large sharks including great whites − known to reach lengths of 20 feet, the small cigar-shaped shark typically does not attack people in open water. However, they have been known to attack objects much larger than themselves like seals and even nuclear submarines, researchers with the institute said.

Two days of attack

In an Instagram post, the group wrote, the sharks first attacked the boat on Monday, leaving "the rear left ball" of the catamaran damaged.

"In an emergency state, the travelers lasted for about a day, they managed to travel about a hundred miles," the group wrote.

The next day, the group said, the ship was attacked again by sharks - this time causing the catamaran to lose its balance and begin to sink.

Crews said they issued an SOS and, about 45 minutes later, the catamaran was approached by a Panama-flagged passing container ship. At that point, the group reported, the captain decided to abandoned the sinking catamaran at sea.

The sinking ship, a radio beacon and an at-sea rescue

An alert from a radio beacon on the catamaran led rescue crews to the vessel about 1:30 a.m. local time, maritime officials reported.

Rescue crews on a Cairns-based Challenger Rescue Aircraft, who confirmed the vessel was damaged from shark attacks, then rescued the three sailors and transported them to shore just outside Brisbane, Australia on Thursday, according to the group and maritime officials.

No injuries were reported.
