While it is rare, an Orca (also known as a killer whale) has the strength and ability to flip a small boat or kayak. Orcas are highly intelligent and social animals that are known to be curious and playful, and sometimes they may approach boats to investigate them.
Since 2020, there have been over 100 'interactions' where boats have been spun around, pushed, rammed, or damaged. According to Marine Industry UK, initially scientists identified three culprits. By 2022, however, the number is up to 17 individual Orcas who have participated in the attacks.
This is the horror moment a crew of a sinking yacht watched a pod of orcas circling their boat after being attacked in the Atlantic. The 7 metre beasts pounced on the French boat off the coast of Portugal last week and relentlessly smashed into the vessel for 45 minutes before it sank.
Scientists hypothesize that orcas like the water pressure produced by a boat's propeller. "What we think is that they're asking to have the propeller in the face," de Stephanis says. So, when they encounter a sailboat that isn't running its engine, "they get kind of frustrated and that's why they break the rudder."
“In interactions with killer whales,” they say, “it is advisable to turn off the engine, lower the sails, leave the rudder set straight, disconnect the automatic and turn off the depth sounder, be silent and do not lean out over the side of the boat.”
Species Act. As a boater or paddler, you can do your part to protect whales and keep yourself safe by following Be Whale Wise regulations, which include: Stay at least 300 yards from southern resident killer whales and at least 400 yards out of the path behind or in front of the whales.
They have been reported to do it (a right whale was filmed breaching onto a boat in South America). But considering the number of boats--some extremely tiny--that share the waters with dozens of whales around Juneau, it's astonishingly rare for any whale-initiated contact to occur.
According to figures from the International Whaling Commission (IWC) Ship Strike Database, there were 605 confirmed, known as definite, collisions between a whale and a vessel between 1820-2019, although the IWC concedes that many incidents aren't reported.
The sinking of the Essex, a whaling ship out of Nantucket, Massachusetts, was the inspiration for Herman Melville's Moby Dick. On November 20, 1820, the American whaling ship Essex was rammed by a sperm whale (Physeter macrocephalus) and sunk.
Is it safe to swim or dive with Orcas? Yes, however, you have to be very cautious, because they are still wild animals and need attention all the time. Orcas owe their name “killer whale” to the early whalers Because they apparently attacked and killed all other animals, even the largest whales.
Beachgoers are always advised to stay far away from, and not touch, a deceased beached whale. This is because when the gaseous pressure inside the whale builds up to dangerous levels, it can have 'explosive' consequences.
SeaWorld apparently did not see it that way, and the killer whale shows have continued as before, only now the trainers do not perform any water work with the orcas. This of course saves trainers from being attacked but does nothing to relieve orcas from the frustrations and anxieties of incarceration.
IDLE: If a whale approaches you, shift your engine to neutral or shut down and allow the whale to pass. Don't park in the whale's path, even if your engine is off. If dolphins or other cetaceans are bow riding, slowly reduce your speed. LIMIT: Limit your viewing time to 30 minutes or less.
These scientists uncovered evidence that pilot whales can thoroughly unsettle orcas.
The whales seem to understand people, and are eager to cooperate and create bonds. In fact, the only apparent instances of orcas attacking people have happened at aquatic parks, where the whales have killed trainers. Many experts think these attacks are not malicious, rather a case of play getting out of hand.
In conclusion, orca whales are not generally considered dangerous to humans. These intelligent, social creatures are generally not aggressive towards humans and have a diverse diet that does not include human prey.
In the wild, there have been no reliably verified fatal attacks on humans. In captivity, there have been several non-fatal and four fatal attacks on humans since the 1970s. Experts are divided as to whether the injuries and deaths were accidental or deliberate attempts to cause harm.

On February 24, 2010, Tilikum killed Dawn Brancheau, a 40-year-old SeaWorld trainer. Brancheau was killed following a Dine with Shamu show. The veteran trainer was rubbing Tilikum as part of a post-show routine when the orca grabbed her by her ponytail and pulled her into the water.
There are no documented reports of wild, free-living orcas ever having intentionally attacked humans. The name 'killer whale' derives from 'killers of whales', not killers of people.
Although not generally deep divers, foraging killer whales can dive to at least 100 m (328 ft.) or more. The deepest dive known for a killer whale, performed under experimental conditions, was 259 m (850 ft.).
Over 100 incidents involving orca whales have been documented since 2020, two of which resulted in sunken yachts. Approximately 15% of boats that encounter orcas require towing to shore afterward.
Dear EarthTalk: Is it true that military sonar exercises actually kill marine wildlife? Unfortunately for many whales, dolphins and other marine life, the use of underwater sonar (short for sound navigation and ranging) can lead to injury and even death.
The stomach walls are very thick and muscular, to grind up fish and giant squid, before they pass to the other chambers and digest in the gastric juices. There is no breathable air in a whale's stomach, so you would have at most three minutes before you asphyxiated.
Orcas, or killer whales, are the largest of the dolphins and one of the world's most powerful predators.
