While specific numbers vary, hundreds of boats, mainly sailboats, have been involved in interactions with orcas (killer whales) since 2020, primarily off Spain and Portugal, leading to several sinkings, though no human injuries, with a small pod responsible for this unusual behavior, which has also been historically documented, notes Wikipedia and The Guardian.
Over 250 boats have been damaged by the orcas and four vessels have sunk. The frequency of attacks has increased over time. From July until November 2020, 52 orca interactions were reported. The behaviour continued into 2021, with another 197 interactions recorded, and into 2022, with 207 interactions.
While an accidental collision with a sperm whale at night accounted for sinking of the Union in 1807, the Essex incident some 30 years beforehand was the only other documented case of a whale deliberately attacking, holing, and sinking a ship.
A history of orca boat encounters
More than 250 boats were reported to have been damaged between 2020 and 2023. Encounters peaked in 2023 with 207 recorded during the year, dropping to 136 in 2024, and just 67 so far in 2025.
Candidate in Environmental Policy and Management at Middlebury Institute of International Studies. Each year, an estimated 20,000 whales are killed worldwide by vessel strikes, according to Dr. Douglas McCauley, Director of the University of California Santa Barbara Benioff Ocean Science Laboratory.

Karen Harris orcas are one of the most vicious ocean predators, they don't just kill for food, they also kill for pleasure and they torture their prey. If you want to call them killer dolphin instead of killer whale, by all means go ahead, but they're the humans of the ocean.
2025 at 1500 LT 3-4 killer whales attacked our vessel, a 30-meter tallship STS Kapitan Głowacki The attack lasted about 40 minutes. Speed: 2.5 knots, heading: 030, engine only. The killer whales were striking the rudder blade.
Although the great white shark has a fearsome reputation, in a straight fight it is outclassed by the orca. Not only are orcas much bigger, they are also smarter.
ADVERTISING. While the San Diego park has yet to exceed — or even reach — its peak annual attendance milestone of 11 years ago, it ultimately weathered a yearslong “Blackfish” backlash from both the public and animal rights activists and retained its appeal as a marine theme park while doubling down on thrill rides.
If the whale is within 400 yards of your vessel, immediately disengage the transmission until the whales have moved out of the area, if it's safe to do so. Sailors should luff sails and wait for the whales to move on, and kayakers, group together out of the path of the whales.
One of the key elements for avoiding ship strikes that is covered in the training course is the reduction of vessel speed. As well as minimising the risk of collision with whales, reducing vessel speed has several additional benefits for the climate and marine environment.
Winner of the National Book Award for Nonfiction and on the New York Times bestseller list for 40 weeks, this “spellbinding” (Time) “page turner” (New York Times) tells the true story of the 19th-century whaleship Essex out of Nantucket that got rammed by one of the largest whales anyone had ever seen, the whale that ...
Vessel strikes and entanglement in fishing gear are the greatest human threats to large whales.
When you think of top ocean predators, you probably think of sharks. Great white sharks, to be exact. But the true ruler of the sea is the killer whale.
Of all the ocean predators, the great white shark seems like it might be best able to take on an orca. These huge sharks can measure up to 6.4m long and weigh as much as 2,041kg (that's heavier than a Ford Focus).
The orcas use their powerful jaws and teeth to inflict fatal wounds on the sharks, and then consume their liver, which is a nutrient-rich organ.” A-Z Animals also notes, “According to a 2019 report, orcas that relocate to an area to hunt seals will drive away any great white sharks that previously resided in the area.
SeaWorld finally acknowledged the significant shift in public opinion on orca captivity and made its historic announcement that the current generation of orcas at SeaWorld will be its last. A combination of relentless protests, canceled corporate sponsorships, and celebrity outcry led to the landmark decision.
Orcas are apex predators, meaning that they themselves have no natural predators. They are sometimes called "wolves of the sea", because they hunt in groups like wolf packs. Orcas hunt varied prey including fish, cephalopods, mammals, seabirds, and sea turtles.
Scientists agree that the bowhead whale has the longest lifespan of all marine mammals. Whales are the largest animals on Earth and live longer than all other mammals in the contemporary animal kingdom.
Is it dangerous to swim with orcas? We get this question a lot, and the answer is no. In over 30 years of running these expeditions, we've never had any accidents involving orcas.
