#ferries - A Royal Navy nuclear-powered submarine has been involved in a near-miss with a ferry in the Irish Sea.
An investigation writes The Irish Times, has been launched into the previously unreported incident, which occurred on November 6th.
The ferry was Stena Superfast VII, which operates between Northern Ireland and Scotland.
It has a capacity for 1,300 passengers and 660 cars.
The submarine was submerged at the depth needed to extend its periscope above the surface of the water.
The Royal Navy would not confirm which of its 10 submarines was involved.
They are all nuclear-powered but only four carry Trident nuclear missiles.
A spokesman for the Marine Accident Investigation Branch (MAIB) said: “In November, we were notified of a close-quarters incident between the ro-ro [roll-on/roll-off] ferry Stena Superfast VII and a submarine operating at periscope depth.

According to The Scotsman, it's believed the search has been ongoing for more than a week after a vessel was detected north of Scotland, though the UK's Ministry of Defence would neither confirm nor deny such a search was taking place.
The news comes some three months after a Donegal crab boat reported a near-miss with a submarine off Tory Island on Ireland's North Coast.
It's not known what country's military that submarine represented, but it is feared that Russian subs might be secretly surveying undersea internet cables for potential strategic advantage.
However, searches for such rogue submarines have been blamed by environmentalists for prompting significant whale strandings, as reported on Afloat.ie earlier this year.

#Fishing - Donegal fishermen are counting their lucky stars after a near-miss with a submarine last week.
As TheJournal.ie reports, Seán Ó Briain says his crab boat came within just 200 metres of the sub, which appeared with little warning about 22km northwest of Tory Island last Thursday (3 September).
While the "general rule", according to Ó Briain, is to give right of way to fishing vessels such as his when setting or pulling pots, in this case "we needed to slow down to let the submarine pass".
Ó Briain added that daylight added to their luck both this time and in a similar incident this time last year, as they were able to take evasive action.
The story will bring to mind an Ardglass skipper's complaint that his prawn trawler was dragged backwards by a submarine in the Irish Sea this past April – an incident finally confirmed by the Royal Navy on Monday (7 September).
According to the Belfast Telegraph, Britain's Ministry of Defence admitted to the incident, which caused an estimated £10,000 worth of damage to Paul Murphy's boa and fishing gear, after "new information" came to light. More on the story HERE.
#MarineScience - Following its issue by the Central Bank last year, the limited edition Silver Proof coin commemorating John Philip Holland, the Irish-born inventor of the modern submarine, was presented to Taoiseach Enda Kenny and Marine Minister Simon Coveney during their recent visit to the Marine Institute.
Highlighting the significance of Ireland's strong maritime history, Marine Institute CEO Dr Heffernan explained how this country "is at the cutting edge of international marine research driving ocean discovery and exploration.
"Supporting the Irish-led first transatlantic mapping survey from Newfoundland to Galway this coming month [June 2015], the Marine Institute's national research vessel RV Celtic Explorer will be using its extensive multibeam sonar equipment mapping parts of the Atlantic seabed."
Dr Heffrnan added: "The oceans are the life support system of our planet – producing half the oxygen we breathe; providing us with a wealth of resources including food, minerals and energy; as well as affecting our moderate climate in Ireland. It is essential that we continue to improve our understanding of how the ocean impacts our live."
By 2020, in partnership with the Atlantic Ocean Research Alliance between the EU, Canada and USA which was established by the signing of the Galway Statement in 2013, Dr Heffernan says "we aim to be able to predict the major risks and changes in the dynamics of the Atlantic Ocean.
"Just as John Philip Holland set out to discover the depths of the sea over one hundred years ago, we continue this quest of discovery and innovation through advanced technology."
That's what the crew of an Ardglass prawn trawler are saying after an incident yesterday afternoon (Wednesday 15 April).
As the Belfast Telegraph reports, skipper Paul Murphy says the 60-foot wooden-hulled trawler was some 18 miles off the coast, near the Calf of Man, when something snagged its nets.
“Without warning, were were stopped and pulled backwards very violently at around ten knots which is the top speed of the vessel. I really thought that was it," he says.
"It was fortunate that one of the steel ropes holding the net snapped or we would have been pulled under very quickly."
Murphy says the scary episode only lasted a few seconds, but still managed to cause thousands of pounds' worth of damage to his fishing gear – and alleges that the culprit was a submarine.

It wasn't the only drama in the Irish Sea yesterday, as a coastguard helicopter was scrambled to rescue three from a fishing boat that sank off Wicklow.
#submarine – The Central Bank of Ireland launched today a €15 limited edition Silver Proof collector coin to commemorate John Philip Holland [1841 - 1914], the Irish born inventor of the modern submarine.
Speaking at the launch at the Marine Institute, Oranmore, Galway, Central Bank Director of Currency and Facilities Management, Paul Molumby said: "This is the first in a new series that the Central Bank will issue to honour Ireland's impressive scientific and technological tradition. John Philip Holland's life and achievements were extraordinary. He played a significant role in the development of submarine navigation and following his emigration to the USA, he designed the first working submarine."
Dr Peter Heffernan, CEO Marine Institute said: "We're delighted to host the launch of the Central Bank's commemorative coin here today to honour John Philip Holland, the Irish born inventor of modern submarine. As a nation we have a strong tradition of innovation and we at the Marine Institute are very proud to maintain that link with the history of marine technology - we named our remote operated vehicle (ROV) after John Philip Holland the Irish born inventor of modern submarine.
With the ROV Holland I, we honour his legacy through important recent scientific discoveries such as the surveys of mid-Atlantic volcanic vent fields and the unique new animal communities on the deep canyons on our continental slope, as well as working on crucial fisheries, environmental and climate changes missions and assisting in the development of new marine sensor technologies.
This event would have also been well received by the late Commander Bill King who lived in Oranmore, Galway. Commander King had commanded the submarine Snapper during World War II, in which he won the DSO and DSC while patrolling the coast of Norway. In his later years he frequently addressed meetings urging people to seek adventure in their lives, particularly having joined the Royal Navy at a young age of 13.
The coin features a representative image of the inventor's hand poised to place the final stroke of a technical drawing of the USS Holland, complete with a decorative nautilus spiral with the obverse bearing the traditional representation of the Irish harp. The coin, which was designed by Mary Gregoriy, is part of the Irish Science and Inventions coin series, and has an issue limit of 10,000 units.
The Holland coin will be available to the public from Tuesday 2nd September 2014. Coins can be purchased by downloading an order form from www.centralbank.ie, by phoning 1890 307 607 or directly from the Central Bank on Dame Street in Dublin at a cost of €44.
#Submarine - Could a supersonic submarine speed through the Pacific Ocean from San Francisco to Shanghai in less than two hours?
The Chinese engineers behind some remarkable new sub-sea technology seem to think so, as the South China Morning Post reports.
Their 'supercaptivating vehicle' design uses gas jets to envelope a vessel inside an air bubble that severely reduces the friction or drag experiences by objects moving through water.
In practice, the technology was developed by the Soviet military to send a torpedo rocketing through the water at an incredible 370km/h.
In theory, the same principles could be adapted to fit a much larger vessel such as a passenger submarine and send it zooming through the depths at a barely fathomable 5,800km/h – the speed of sound under water – and cut a transpacific trip to just 100 minutes.

As The Irish Times reports, the modern submarine was pioneered by John Philip Holland, who worked as a teacher in the Boyne-side town before emigrating to the States and developing his submersible ideas for the US Navy.
The rest is history, as Holland's designs formed the basis of all modern submarines we know today.
Strangely enough, his story is entwined with that of another Irishman, Louis Brennan, who invented the world's first practical guided torpedo.
Holland died just weeks before the HMS Pathfinder became the first ship to be sunk by a submarine-launched underwater missile.
But his legacy is not all destruction, and better exemplified by the exploration work being done in the Whittard Canyon by the Marine Institute's unmanned submersible ROV Holland I, named for one of the Irishman's early submarine prototypes.

#INLAND WATERWAYS - It was a hotly anticipated find - but the image of what appeared to be a rare German submarine in the depths of Lough Foyle turned out to be a ghost.
RTÉ News reports that a team brought in to verify a sonar image captured by a search and rescue team from Mallow have confirmed that it was a 'sonic illusion'.
Northern Ireland's Environment Minister Alex Attwood called in the experts after the search team discovered what looked like the outline of a midget U-boat on the lough bed near Derry.
The possibility was a real one, as the lough had been a major naval base during the Second World War.
But a full survey of the lough revealed that the original image was an apparition caused by sonar distortion.
"There is no doubt for a moment there was a thrilling possibility which has now not come to pass," said the minister. "I do share a sense of disappointment."

Cork gardaí are investigating the looting of items from a First World War U-boat recently discovered off Roches Point.
The Irish Times reports that the submarine also appears to have been damaged by the illegal salvagers.
A spokesperson for the underwater archaeology unit of the Department of Arts, Heritage and the Gaeltacht confirmed that reports had come in from divers regarding disturbance of the wreck site - noting attempts to remove parts of the structure, and details of human remains.
Divers with the unit were expected to assess the site as soon as weather permits.
Items believed to have been taken include sailor's attire belonging to the crew of the 49-metre German vessel UC-42, which sank in 1917. The German embassy has indicated its "legitimate interest" in the preservation of the wreck.
