Below the surface of the bay there are meadows. Eelgrass meadows, swaying in the cold green water, and beds of pink coralline maerl that look like underwater coral but are alive in their own slow way. There are reefs built by horse mussels stacked together, and forests of kelp where the bottom drops away. Ramsey Bay covers 94 square kilometres off the northeast corner of the Isle of Man, from the Point of Ayre at the island's northern tip down to Maughold Head, and most of what makes it special you would never see from the deck of a boat.
In October 2011, under the Wildlife Act 1990, the whole bay was given statutory protection as the Isle of Man's first Marine Nature Reserve. The science behind the designation was straightforward: the bay holds internationally significant areas of eelgrass, horse mussel reefs, kelp forests and maerl - habitats that act as nurseries for commercially important fish, shellfish and crustacea. Some parts of the reserve are highly protected. Other parts form a 'fisheries management zone' co-managed by the Manx Fish Producers' Organisation and the Department of Environment, Food and Agriculture, with very little of that zone actually fished. The bay is also a core marine area of the island's UNESCO Biosphere Reserve. Right at its centre lies the Ramsey Mooragh Shore Area of Special Scientific Interest, and the entire coast has been designated an Area of Ecological Importance in the local plan. As of 2019 a controversial marina proposal would infill the South Beach and build a new harbour inside the reserve - a fight that has been quietly running for years.
In July 1964, a strange visitor arrived in the bay and stayed for almost four years. The original Radio Caroline ship, which had been broadcasting pirate pop music off the Essex coast, slipped away from the southeast of England and sailed north. It dropped anchor in Ramsey Bay and began broadcasting as Radio Caroline North, beaming the records the BBC would not play across the Irish Sea to listeners in Belfast, Liverpool, Glasgow and the north of England. The British government tried to outlaw it; the audience grew anyway. The ship rode at anchor here through summers and winters until March 1968, when creditors finally caught up and it was towed away. For four years, one of the most influential broadcasting operations in British pop history floated in this bay.
On the night of 7 March 1956, the Fleetwood-based trawler Fleetwood Lady anchored in Ramsey Bay so that three of her crew could go ashore and see their families. The six men - Allan Bradford, Arnold Brew, Albert 'Abby' Cottier, Eric Lyall, his son Eric James Lyall, and Reginald Wright - rowed in together. Later, when they rowed back out toward the trawler, the boat capsized. None of them made it home. A father and son were among the lost. In March 2002 a plaque was unveiled in the town to remember them. It is a small monument for a small disaster in a long history of the sea, but on the Isle of Man almost everyone is one or two people away from someone who fishes, and so the names still mean something here. The Ramsey lifeboat has been on station since 1829 in part because of nights like that one.
Stand on the long sandy beach north of the harbour on a clear day, and the bay opens out east across nineteen kilometres of water before the Lake District peaks of Cumbria climb out of the haze on the English mainland. Whitehaven is 36 miles northeast. The water is colder than it looks. The sand is firm enough to walk a dog on, and the dog will probably get muddy at the south end where the Sulby River pushes out across the harbour swing bridge. The slow currents at the Point of Ayre keep reshaping the gravel beach at the northern tip, and grey seals haul out on the shingle there. The bay holds a remarkable amount, in other words, for a sweep of water that most maps barely label.
Ramsey Bay opens onto the Irish Sea at roughly 54.35N, 4.30W on the northeast coast of the Isle of Man, running 18 km (10 nm) from the Point of Ayre lighthouse at the northern tip to Maughold Head in the south. From altitude the bay reads as a broad curving inlet, with the town of Ramsey at its southwest corner and the long northern sandy beach running up to the Point of Ayre. Nearest airfield is Ronaldsway (EGNS) 18 nm S; former RAF Jurby strip is 5 nm W of the bay's centre. On clear days the Cumbrian fells are visible across the water to the east.
