Coleraine is a small town on the north coast of Ireland situated on the River Bann about five miles above the entrance. It provides berthing at a choice of two fully serviced marinas one just a mile north of the town and another alongside the town quay.
The River Bann provides complete protection and all-round shelter. River access is straightforward between well-lit stone training walls assisted by alignment beacons and leading lights. Once through the entrance, there are no issues progressing up the well-marked river to Coleraine Marina. The entrance, however, is subject to swell, outflow overfalls, and dangerous surf in moderately adverse conditions where careful planning is required. In the worst case, with north and northwest gales, the sea breaks right across it rendering it impassable. Consequently, no attempt should be made by a newcomer in any onshore winds of Force 6 or above.

What's the story here?

Image: Michael Harpur
Coleraine is a large town and small port that stands on both sides of the River Bann 4½ upriver from the entrance. It is the largest town on the Causeway Coast and it is sited at the lowest bridgeable point of the river where it is 90 metres wide. The River Bann is the longest river in Ulster, with the Lower and Upper Banns combined its length is 129 km or 80 miles. Exiting into the Atlantic at Barmouth, on the north coast, the river winds its way from its source in the Mourne Mountains, situated in the southeast corner of Northern Ireland, pausing in the middle to widen into the enormous Lough Neagh.

Image: Michael Harpur
The port town of Coleraine offers visitors a choice of two riverside marinas, Coleraine Marina and Coleraine Harbour. Coleraine Marina is on the northeast bank of the river, 4 miles from the entrance and one mile north of the town of Coleraine. The Coleraine Borough Council-run modern 105-berth marina can accommodate vessels of up to 18 metres LOA with draughts of 3 metres LAT at the outer pontoons, reducing to 1.4 metres LAT nearer the bank.

Image: Michael Harpur
Fifteen berths are available for visitors and typically, most boats visiting Coleraine stay here. Contact the marina

Image: Michael Harpur
A mile upriver Coleraine Harbour has quayside pontoons on both banks of the river and at the heart of Coleraine. Contact the Harbour Master

Image: Michael Harpur
Leisure craft carrying any airdraft will however require a railway bridge lift to proceed upriver to Coleraine Harbour. The bridge is situated a ⅓ of a mile above Coleraine Marina and has a clearance of 4.9 metres HAT. The lift can be arranged via the Harbour Office during office hours.
How to get in?

1¼ miles west of the entrance stands the conspicuous and classical Mussenden Temple which provides a good marker for the entrance. This is a white tower approximately 5 metres in height situated on the edge of the rocky cliffs overlooking Castlerock Strand which leads to the entrance.

Keeping a ½ mile offshore on the western approaches to Barmouth from the west will be clear of all dangers.

Before progressing, check that there are no commercial traffic movements which run up to Coleraine Harbour. The harbour office announces traffic movement on VHF Ch. 12 during its office hours and it is advisable to maintain a listen on this channel when operating in the River Bann. Carefully monitor conditions for signs of breaking water. As a rule, the entrance must not be attempted in strong onshore winds when overfalls are visible on the approach or the swell is noticeably breaking upon the ends of training walls.
If in any way uncertain it is advisable to contact the Harbour Office

Image: Michael Harpur
The east pierhead has a 4.5-metre-high white pyramidic concrete tower.
Barmouth East Pierhead - Fl R 5s 6m 2M position: 55° 10.323'N, 006°46.338' W
The west pierhead has an unlighted metal (rusted) post at its head. A starboard-lighted pole, Fl G 5s 4m 2M is set back about one-third of the way along the wall or about 40 metres from the pierhead of the West Mole. It is obscured from north round to west and the pole itself is deeply rusted so that appears a brownish colour.

Image: Michael Harpur
The leading light beacons are set on the west bank of the river at an elevation of 6 metres and 14 metres. The front is situated south-southeast of the entrance and it is a 5-metre-high white pyramidal metal tower; Oc 5s 6m 2M.

Image: Michael Harpur
The rear is situated approximately 300 metres further south-southeast in the sandhills and it is a white square concrete tower; Oc 5s 14m 2M.
Barmouth rear Alignment Marker - Oc.5s.14m2M position: 55° 9.869' N 006° 46.173' W

From the initial fix, identify the leading marks and steer in keeping them in line on 165° T. Expect to pass over the sandbar which is constantly moving on this transit. It is dredged to a minimum depth of approximately 3.5 metres LAT.
Pass in the 45-metre wide channel between the pierheads of the training walls which has a least depth of 2.9 metres. Keep well clear of the area off the ends of the pierheads and tend towards the east wall as the western wall is foul with boulders.
Once inside the river channel maintain a uniform width of about 200 metres and a depth of 3.4 metres to Coleraine. This is well marked with lit beacons; green Fl G 5s on the southwest side and red Fl R 5s on the northeast side.

Image: Michael Harpur
The only odd exception is the first encountered No. 2 port hand beacon off Ballyaghran Point. This stands opposite the front leading mark which appears almost centre-channel with a Lt Fl R 3s. Nevertheless, pass this to port as depths reduce abruptly outside the marked channel in the River Bann.

Image: Michael Harpur
From here it is simply a matter of following the well-marked channel to Coleraine that has a least width of 45 metres all the way. It is possible to anchor immediately inside the entrance of the Lower Bann

Image: Michael Harpur
The first marina encountered is the private separately covered Seatons Marina

Image: Michael Harpur
Seatons Marina is a family-run marina that is fully occupied by local vessels. The marina is oversubscribed but may be able to accommodate a visitor in a vacant berth.

Leisure craft carrying any height and intending to proceed to Coleraine Harbour will require the opening of the railway bridge to pass upstream. It has a clearance of 4.9 metres HAT and a request to open can be made by contacting the Harbour Office in advance during working hours.

Image: Michael Harpur
Once past the railway bridge, the first pontoon will be seen attached to the quays on east side of the river 450 metres upriver of the bridge.

Image: Michael Harpur
The Riversdale Quay, on the east bank 300 metres upriver, will open up once abreast of the first pontoon. Berth as arranged with the Harbour Office.
Why visit here?
Coleraine takes its name from the Irish 'Cúil Raithin' meaning 'corner/nook of ferns' or 'ferny corner'. Legend has it that this name goes back to the 5th Century and the coming of St Patrick. The Saint was received here with great honour and hospitality by the area's chieftain named 'Nadslua'. He offered the Saint a site to build his church next to the River Bann. The area was overgrown with ferns, a 'nook of ferns', which lent the church the name and by extension the area. This name was later anglicised as Colrain, Colerain and finally Coleraine.

But Ireland's history runs much deeper here than the 5th century. Coleraine is home to the Mountsandel which is situated one mile above Coleraine, rising to a large mound or mount, which gives the site its name, that towers over the right or east bank of the river. Flint tools found here indicate that Stone Age hunters camped here to fish salmon in the natural weir. Their ancient wooden houses were excavated and carbon dated to 7,800 BC. This makes this the earliest known settlement of Ireland's first hunter-gatherers. Dating back nearly 10,000 years to the Mesolithic or Middle Stone Age period the site is often referred to as 'the cradle of humanity in Ireland'.

Image: © Pure Chief
The mount was used as a fort from the Late Bronze Age (900-300 BC) if not earlier when it was then called 'Dun-da-bheann'. Pronounced 'dun-davan', or the fort of the two peaks or gables, it was the residence of a chief called 'Niall of the brilliant deeds' a little before the Christian era, and which is celebrated in ancient Irish romance. It was converted into a motte by the Normans in the 13th century and re-used as an artillery emplacement during the 1641 rebellion. The great fort or mound, one of the largest in the country, may be accessed through Mountsandel forest with the closest entrance being near the side of Coleraine Courthouse.

Coleraine itself dates back to the medieval period. The Dominican Friary or Abbey, remembered by Abbey Street, was founded in 1244. Being situated at the lowest bridgeable point of the River Bann, where the river is 90 metres wide, Coleraine has always been a strategic area that has been hotly contested through the centuries. It was placed under siege twice by both Kings of Munster and Ulster. The town was also subject to the Elizabethan, Cromwellian and Williamite wars and become the first 'planted' town in Ulster. It was given a Town Charter in 1613 to enable the town to sell and export goods to places around the world. Markets were central to the Plantation project as it was assumed that control, regulation and commercialisation of the economy would also establish a 'civilised' society. The Diamond was the market place and it is a common name for the market square at the centre of plantation towns.

Image: National Library of Ireland on The Commons
James I put considerable pressure on the London Livery Companies or Guilds to become involved in the Ulster scheme in Coleraine. The Guilds were descended from the Medieval Guilds which were created to defend the positions of workers in a wide range of trades. By the 17th century, they held considerable wealth and were looking for investment opportunities. Backed by the companies of the city of London, a commercial basis was created from which Coleraine developed from two urban communities and a fortified town was built on the east bank. This was besieged in the 1641 rising and estimates suggest that up to 2,000 inhabitants died, mostly of disease. Many of the other Londonderry settlements were attacked in this rising and some, such as Movanagher, were abandoned and never rebuilt.

But Coleraine succeeded because it was built on an established ecclesiastical and trading centre, at a strategic crossing on the Bann close to rich local fisheries and forests. In 1829 The Market Yard was built and the market moved to its new venue. Today the Causeway Speciality Market brings the market back into the Diamond. The slightly skewed street pattern of Coleraine's town centre is the legacy of that early exercise in town planning. Traces of the lines of ramparts that provided the Plantation town with its defences are also visible.

Image: Tourism NI
Further significant expansion came throughout the 19th century with the arrival of industrialisation. The Moles protecting the entrance to the river were built in the 1880s and repaired and improved in 1929. The river port was expanded and handled cargoes of coal, potatoes and naphtha. The coming of the railway further spurred development but the town was set to see its greatest expansion in the 20th century after the Second World War. This was after the 1965 arrival of one of the campuses of the University of Ulster which effectively doubled the population. After this Coleraine took on all the hallmarks of a university town with the expansion of associated commerce along with the development of sporting and recreational facilities. This bolstered the town's size from an area of less than 2 square km in the early part of the 20th century, to the present more dispersed town of about 11 square km situated on both sides of the river with the University of Ulster on its northern outskirts.

Image: Michael Harpur
Today Coleraine is the principal town on the Causeway Coast a prosperous market town renowned for education, traditional linen, whiskey and salmon fishery. It can be described as a busy town, that quietly retires at night with much of the nightlife being taken up by the nearby seaside towns of Portrush and Portstewart. The town's rich history is reflected in its architecture which may be easily explored via walks around it and along the scenic river banks. The Visitor Information Centre in Coleraine provides a Walking Heritage Trail, 'Around the Ramparts' and also a historical touring route to explore the 17th-century plantation town.

Within the historically significant Mountsandel forest there are two linear paths, one along the top of the slope and the other at the foot of the slope, partly following the line of the river. Walkers can combine the two paths to form a circular route or make use of the steps at the Fort to create alternative routes. Immediately south of the town, there is a weir where the migrating salmon can be seen leaping through a series of steps on their route to their hatching grounds. Alongside this Coleraine has a wide range of local activities available that the visitor centre can best provide advice.

Image: Michael Harpur
From a purely boating point of view, Coleraine offers a vessel complete protection with excellent provisioning. If a bad spell is coming this is the place to run for but in advance of any difficulties that might occur at the entrance. Its range of transport links makes it the ideal place to securely leave a boat and/or visit the Giant's Causeway, a twenty-five-minute bus ride away, and the distillery village of Bushmills, also well-served by buses. The Mussenden Temple, seen atop a precipitous cliff, is also close by overlooking County Donegal in one direction and Scotland in another. The river offers the option to cruise Lough Neigh, highlighted separately in the Lower Bann
What facilities are available?
Coleraine Marina offers visiting Cruisers all facilities and caters for vessels up to 60ft. in overall length. Berths are furnished with water and electricity, and the modern marina building offers changing & showering facilities plus a chandlery that caters for bottled gas. Diesel and petrol are also available and there is a slipway that provides launch capabilities for vessels up to 20ft. Car and cycle hire can be arranged at the office. The marina has a travelift for launching vessels up to 40ft in overall length and 13 tons displacement, and a hard standing for 25 boats.All pontoons have water and electricity and have 24 hour CCTV coverage. Access to the pontoons are by means of an electronic fob. (Gate fobs and electricity cards can be obtained from the Harbour Office).
With a population of almost 25,000, shopping in Coleraine is excellent. Likewise transport connections are good to Belfast 55 miles (88.5 km) to the northwest, and to Derry 30 miles (48.3 km) east, both of which are linked by major roads and railway connections. Therefore the City of Derry Airport, and Belfast International Airport, the main regional airport to the south, and George Best Belfast City Airport to the southeast, are all relatively accessible from Coleraine. The Riversdale Quay in Coleraine has a 35 tonne derrick crane available for lifting yachts where some maybe lifted with masts rigged. Some space is available for wintering here on the hard, in the open or undercover.
Any security concerns?
The marina has twenty four hour security.With thanks to:
