Widespread characterisation of orca whale interactions with yachts as “attacks” is “heavily loaded and highly contestable”, according to an article in The London Review of Books.

Over the past three years, a number of yachts have been sunk in encounters with the whales in an area now known as “Orca Alley” near the Straits of Gibraltar and off the Iberian peninsula.

As London Review of Books contributing editor Francis Gooding writes, at least 11 individual whales in a small population of around 40 have been identified as participants.

Orcas are “thought to indulge in behavioural fads, which can spread through groups quickly before petering out,” he writes.

“The most famous of these involved three pods in Puget Sound that in 1987 spent a few weeks carrying dead salmon around on their heads; in 2005, groups in the same area seemed to experience a less benign craze for tormenting and sometimes killing harbour porpoises, a species they do not eat,” Gooding states.

Human pressures on the environment, such as the longline fisheries for tuna, have been cited as one reason by a working group which studied Iberian orca behaviour.

However, Gooding recalls a period in history where orcas and humans hunted together. From the 1820s, pods of orcas near Twofold Bay in New South Wales assisted the men of the Eden whaling station in killing of baleen whales.

“Specialised focus, communicative teamwork and great adaptability means that – also like human beings – orcas can have a hugely disruptive effect on ecosystems when they choose to turn their attention to a new source of food,”he writes.

He cites Hal Whitehead and Luke Rendell, authors of The Cultural Lives of Whales and Dolphins, who documented how a small group of orcas near the coastal kelp forests of the Aleutian Islands started hunting sea otters in the 1990s.

Having almost eliminated the otters from a large area of the Aleutian coast, the kelp-eating sea urchins, which had been controlled by the otters, then “mowed down” the kelp forests, and left a barren seascape.

“Orcas may have had impacts on the ocean not dissimilar to the ways early humans affected terrestrial ecosystems, and as far as ecologically destructive overkilling goes, it is even possible that the deep history of the orca as a hunter contains a parallel with the rapacity of human behaviour,” Gooding writes.

“The appearance of orcas around ten million years ago correlates with the sudden and mysterious disappearance of more than half the known species of cetaceans, seals and sirenians (dugongs and manatees) from the fossil record,” he writes.

“As with the widespread extirpation of terrestrial megafauna from areas colonised by humans during the Pleistocene, one hypothesis is that orcas, as they expanded into new marine ecosystems, hunted many existing sea mammals to extinction,” he says.

A scientist researching orca attacks on yachts off the Iberian coast says they are doing it for the “adrenaline shot”.

As The Evening Standard reports, marine biologist Renaud de Stephanis said he believed the whales were ramming boats for fun, and not out of malice.

At least three boats have sunk in some 500 incidents recorded since 2020.

“Don’t ask me how they started it because I don’t know, and I don’t think anyone ever will. What we do think is that it is a simple game for them,” de Stephanis is quoted as saying.

He is completing a report on the orca behaviour for the Spanish Ministry of Ecological Transition.

He referred to one particular orca that has a deep scar on its back, believed to have been caused by hitting an engine propeller.

“She belongs to a family of seven members and as far as we know, she is the most active of all,” he said.

Underwater cameras have helped researchers capture numerous videos of the incidents since they began in 2020.

A separate report published by LiveScience in May of this year quoted scientists who believe a traumatic event may have triggered a change in behaviour of one orca which the rest of the Iberian orca population had learned to imitate.

Marine biologist Alfredo López Fernandez of the University of Aveiro in Portugal and representative of the Grupo de Trabajo Orca Atlántica, or Atlantic Orca Working Group, said that “ defensive behaviour based on trauma, as the origin of all this, gains more strength for us every day”.

The Iberian orca population is listed as critically endangered, with just 39 of the animals recorded in the last census in 2011.

A boat captain has shared video of the moment his vessel was ambushed by an orca in the Strait of Gibraltar, as Newsweek reports.

The footage captured by Dan Kriz documents one of a spate of attacks by orcas on vessels in the area since spring, leaving experts baffled.

It’s not the first time that Kriz has felt the wrath of such marine wildlife, as he recounts being ambushed in the same stretch of water in 2020.

But he characterises his most recent ordeal on 15 April as more deliberate.

“It didn’t take them that long to destroy both rudders,” he said. “Looks like they knew exactly what they are doing. They didn’t touch anything else.”

Marine wildlife experts are divided over this unusual behaviour, with some attributing it to mere play while others suggest it could be one vengeful orca teaching others how to attack the boats.

A pair of killer whales from a unique group have been sighted off the Kerry coast, as Radio Kerry reports.

The Irish Whale and Dolphin Group (IWDG) has identified the two male orcas seen off Bray Head on Valentia Island this week as the last known surviving members of the Scottish West Coast Community Group.

And according to the Mirror, it marks the second sighting for the pair in this area within the last three months.

Studied for years by marine scientists due to isolation their genetic distinctiveness from other orcas in the North Atlantic region, these marine mammals commonly feed in the Hebridean Islands.

But they’ve previously been found as far as Scotland’s east coast, Lough Swilly in Donegal and four years ago off the Blasket Islands, likely in search of food.

Experts have feared for some time that this orca pod has been nearing its end. It last calved more than 30 years ago and has shrunk from around 20 individuals in the 1980s to just two known members, John Coe and Aquarius, as of 2016.

A surfer from Northern Ireland got more than he bargained for when he was chased by a pod of killer whales off Donegal last week.

As the News Letter reports, Derry man Ryan Vail was catching waves off Culdaff on the Inishowen Peninsula last Friday (11 September) when he found himself surrounded by the orca pod consisting of two adults and three juveniles.

Orcas are a rare sight in Irish inshore waters, but the marine wildlife are no strangers to Donegal.

A pod resident in western Scotland has been spotted in Lough Swilly before, and more recently in Strangford Lough, but it has not calved in many years — suggesting these visitors may come from elsewhere.

“I’m well used to the water and have seen basking sharks, dolphins and porpoises, so I knew it definitely wasn’t one of them,” Ryan said.

“I knew what I was looking at, so I also knew I shouldn’t be this close! So, there was a wee bit of panic.”

And that panic only grew when one of the smaller orcas — “the size of a Transit van” — made an aggressive dash for Ryan on his board.

Sightings of an unusual looking bottlenose dolphin off the East Coast in recent weeks have turned out to be a Scottish scrapper named Spirtle.

Images of the dolphin seen off South Dublin and North Wicklow earlier this month showed what appeared to be heavy scarring and discolouration on its right flank.

That was enough for Dr Joanne O’Brien of the Irish Whale and Dolphin Group (IWDG) to identify the animal as the daughter of a dolphin well known in the Moray Firth.

Spirtle’s story is one of survival as almost three years ago to this day, she was found live stranded with significant injuries and suffering severe dehydration.

Since then she’s bounced right back from the brink of death, and it appears she’s now even at the lead of a group of bottlenose dolphins that’s made its way south along the Irish Sea beyond Dublin Bay.

A rare sighting of a different kind was made in West Cork this past week, where a charter boat operator witnessed what he believed was an attack on a pod of common dolphins by a killer whale.

David Edwards was 15 miles south of Galley Head last Tuesday (21 May) when he saw the orca chase after its fellow cetaceans for its lunch — and his images of the event have been confirmed by IWDG sightings officer Padraig Whooley.

#MarineWildlife - Video posted on social media over the weekend of two killer whales spotted off the Co Dublin coast has gone viral.

Trawlerman James Mac Cluskey used his phone to record a few seconds’ glimpse of the pair of male orcas, which came close to his boat some 8km off Rockabill on Saturday afternoon (17 November).

According to the Irish Whale and Dolphin Group (IWDG), it’s the second sighting of the largest species in the dolphin family off the East Coast in recent weeks, with another fisherman reporting an encounter some 22km off Skerries on 30 October.

And it’s believed the duo may be part of the Scottish West Coast Community Group, a unique orca pod long under threat of extinction owning to not having produced any calves for years.

Earlier this year, whales from this group were identified feeding off the Blasket Islands in Co Kerry, showing just how far their range extends.

#MarineWildlife - The RV Celtic Voyager departed the Port of Cork yesterday (Wednesday 24 October) for ‘Operation Orca’, a 12-day survey of an offshore killer whale community associated with the Northeast Atlantic mackerel fishery.

A team of marine scientists from University College Cork is on board the research vessel that’s headed to waters east of the Orkneys, to study the orcas that feed on mackerel between October and February each year.

“This is the first time a dedicated research vessel will be heading up to study these killer whales and we are hopeful to come back with a lot of data,” said PhD researcher and chief scientist Róisín Pinfield in her introductory blog for the survey.

“We will have cameras, GoPros, drones, underwater hydrophones collecting acoustic data so we can hear the killer whales and a RIB so we can get in close if weather conditions allow. Time to pray to the weather gods to keep the storms away!”

The Scientists@Sea blog will be regularly updated by the Celtic Voyager team once they reach the fishing grounds and begin their survey, which runs till Sunday 4 November.

#MarineWildlife - Two killer whales spotted feeding off the Blasket Islands earlier this week have been identified as members of a unique pod from Scotland.

“Killer whale sightings in any Irish waters are rare events, and they seem to be getting rarer,” said Pádraig Wholley of the Irish Whale and Dolphin Group, whose member Nick Massett photographed the orcas in Dingle Bay on Monday 5 March.

Massett identified one of the two cetaceans immediately as John Coe, and its partner as another adult male, Aquarius. RTÉ News says the orcas were likely hunting seals in the area.

Both are members of the genetically distinctive Scottish West Coast Community Group, which commonly feeds in the Hebridean Islands but has previously been found as far as Lough Swilly and Scotland’s east coast, likely in search of food.

“Colleagues from the Hebridean Whale & Dolphin Trust can confirm that John Coe was seen exactly seven days [previously] in Scottish waters … which tells us a lot about the movements of this highly mobile apex predator,” said Wholley.

The Scottish West Coast Community Group has been feared to be on the ‘brink of extinction’ for many years. In January 2016 the pod lost a female member, Lulu, due to what was at first thought to be entanglement with fishing gear but was later blamed on PCB pollution.

RORC Fastnet Race

This race is both a blue riband international yachting fixture and a biennial offshore pilgrimage that attracts crews from all walks of life:- from aspiring sailors to professional crews; all ages and all professions. Some are racing for charity, others for a personal challenge.

For the world's top professional sailors, it is a 'must-do' race. For some, it will be their first-ever race, and for others, something they have competed in for over 50 years! The race attracts the most diverse fleet of yachts, from beautiful classic yachts to some of the fastest racing machines on the planet – and everything in between.

The testing course passes eight famous landmarks along the route: The Needles, Portland Bill, Start Point, the Lizard, Land’s End, the Fastnet Rock, Bishop’s Rock off the Scillies and Plymouth breakwater (now Cherbourg for 2021 and 2023). After the start in Cowes, the fleet heads westward down The Solent, before exiting into the English Channel at Hurst Castle. The finish for 2021 is in Cherbourg via the Fastnet Rock, off the southern tip of Ireland.

  • The leg across the Celtic Sea to (and from) the Fastnet Rock is known to be unpredictable and challenging. The competitors are exposed to fast-moving Atlantic weather systems and the fleet often encounter tough conditions
  • Flawless decision-making, determination and total commitment are the essential requirements. Crews have to manage and anticipate the changing tidal and meteorological conditions imposed by the complex course
  • The symbol of the race is the Fastnet Rock, located off the southern coast of Ireland. Also known as the Teardrop of Ireland, the Rock marks an evocative turning point in the challenging race
  • Once sailors reach the Fastnet Rock, they are well over halfway to the finish in Cherbourg.

Fastnet Race - FAQs

The 49th edition of the biennial Rolex Fastnet Race will start from the Royal Yacht Squadron line in Cowes, UK on Sunday 8th August 2021.

The next two editions of the race in 2021 and 2023 will finish in Cherbourg-en-Cotentin at the head of the Normandy peninsula, France

Over 300. A record fleet is once again anticipated for the world's largest offshore yacht race.

The international fleet attracts both enthusiastic amateur, the seasoned offshore racer, as well as out-and-out professionals from all corners of the world.

Boats of all shapes, sizes and age take part in this historic race, from 9m-34m (30-110ft) – and everything in between.

The Fastnet Race multihull course record is: 1 day 4 hours 2 minutes and 26 seconds (2019, Ultim Maxi Edmond de Rothschild, Franck Cammas / Charles Caudrelier)

The Fastnet Race monohull course record is: 1 day, 18 hours, 39 minutes (2011, Volvo 70, Abu Dhabi Ocean Racing).

David and Peter Askew's American VO70 Wizard won the 2019 Rolex Fastnet Race, claiming the Fastnet Challenge Cup for 1st in IRC Overall.

Rolex SA has been a longstanding sponsor of the race since 2001.

The first race was in 1925 with 7 boats. The Royal Ocean Racing Club was set up as a result.

The winner of the first Fastnet Race was the former pilot cutter Jolie Brise, a boat that is still sailing today.

Cork sailor Henry P F Donegan (1870-1940), who gave his total support for the Fastnet Race from its inception in 1925 and competed in the inaugural race in his 43ft cutter Gull from Cork.

Ireland has won the Fastnet Race twice. In 1987 the Dubois 40 Irish Independent won the Fastnet Race overall for the first time and then in 2007 – all of twenty years after Irish Independent’s win – Ireland secured the overall win again this time thanks to Ger O’Rourke’s Cookson 50 Chieftain from the Royal Western Yacht Club of Ireland in Kilrush.
