Северный канал: пролив между Ирландией и Шотландией

Strait between north east Ireland and Scotland

The North Channel (known in Irish and Scottish Gaelic as Sruth na Maoile, in Scots as the Sheuch) is the strait between north eastern Northern Ireland and south western Scotland. It begins north of the Isle of Man, where the Irish Sea ends, and runs north west into the Atlantic Ocean.

The North Channel connects the Irish Sea with the Atlantic Ocean and is part of the marine area officially classified as the "Inner Seas off the West Coast of Scotland" by the International Hydrographic Organization (IHO). The Straits of Moyle (Sruth na Maoile in Irish and Scottish Gaelic) or Sea of Moyle is the name given to the narrowest expanse of sea in the North Channel between north eastern Northern Ireland (County Antrim) and south western highlands of Scotland (Mull of Kintyre). The narrowest part of the strait is between the Mull of Kintyre and Torr Head, where its width is , making it possible to see across in clear weather conditions. The straits gave their name to Moyle District Council, a local government area in Northern Ireland, and are famed in Irish Celtic mythology through their association with the Children of Lir. In the 1800s, this strait was sometimes referred to in general terms as the "Irish Channel". In the 19th century, Alexander Keith Johnston's suggested name St Patrick's Channel had currency, but it was rejected by the hydrographic department. The deepest part is called Beaufort's Dyke. The North Channel was a favourite haunt of privateers preying on British merchant shipping in wars until the 19th century; in 1778, during the American Revolutionary War, it was also the site of a naval duel between American captain John Paul Jones's USS Ranger and the Royal Navy's HMS Drake. It is crossed by many ferry services. In 1953, the channel was the scene of a serious maritime disaster, the sinking of the ferry Princess Victoria.

The Irish Long Distance Swimming Association (ILDSA) has provided authentication observers for swimmers attempting to cross the approximately span between Northern Ireland and the Mull of Galloway. According to the ILDSA, this was first accomplished in 1947 by Tom Blower. The first two way crossing was completed by a six person relay team on 28 July 2015. The World Open Water Swimming Association note that the North Channel, which it also refers to parenthetically as the North (Irish) Channel, is part of the Ocean's Seven series. This is a set of seven long distance open water swims considered the marathon swimming equivalent of the Seven Summits mountaineering challenge.

In Northern Ireland, Unionist political leaders for decades lobbied the British government to construct a railway tunnel under the Channel, for a better link between Northern Ireland and the rest of the United Kingdom. In August 2007 the Centre for Cross Border Studies proposed the construction of a long rail bridge or tunnel, estimating that it might cost about £3.5 billion. In the Victorian era, engineers proposed a rail tunnel between Stranraer and Belfast. In February 2020, the Prime Minister's Office announced that it had initiated work to examine the feasibility of a bridge between Scotland and Northern Ireland. The transport route with the shortest sailing distance is that between Campbeltown on the Kintyre peninsula (about from Glasgow via minor roads) and Ballycastle, County Antrim (about from Belfast). Campbeltown is on the eastern side of the Kintyre peninsula, but the western side is only about from Torr Head coast to coast. The shortest route between Glasgow and Belfast is the route used by the existing ferry service, that via Portpatrick/Stranraer (about from Glasgow) and Larne (about from Belfast), a coast to coast distance of This route would require the bridge towers to be erected through Beaufort's Dyke, a deep trench, heavily contaminated by 'large quantities' of munitions ('small arms, high explosives and incendiary devices') and nuclear waste that had been dumped until 1950s. First Minister of Scotland Nicola Sturgeon said her mind was not closed to the idea but added "if he [the prime minister] has got £20 bn to build such a bridge going spare at the moment – that could be spent on more important priorities".
