Rules & Regulations

The buoyed channel in Lough Foyle is a narrow channel within the meaning of Rule 9 of the Collision Regs, so keep right and dont get in the way of large ships


The ebb tide spills out beyond Inishowen Head and in NE winds can cause very turbulent seas.The Tuns Bank extends out from Magilligan Point at the extreme NE end of which there is a lit PHM In rough weather the seas break over this bank and the NW side has been known to dry in some years. There is an incomplete breakwater to the South West of Greencastle harbour marked at the outer end by an ECM. This breakwater extends outwards from the Donegal shore for 150m and is causing strong ESE eddies on spring ebbs.

Tidal Data Times & Range

Warren Point - 0430 Dover MHWS 2.3 MHWN 1.9 MLWN & MLWS no data. There is a vast amount of water going into and out of Lough Foyle with each tide and the streams through the narrows can reach 3.5 kts at Springs and 1.6 kts at Neaps. There is a UKHO Tidal Diamond (B) in the middle of the Magilligan narrows which is reproduced in the Charts on this site and gives a good indication of the best time to be in these waters.

General Description

Contacts: For both Greencastle and Moville contact the HM (Frank McDermott)  00353 (0)868166151.

Greencastle lies just inside the entrance to Lough Foyle and is a convenient stop-over for boats cruising the North coast of Ireland but do not want to go all the way up the Lough to Londonderry.  It is well sheltered in all weathers but the entrance will be awkward in strong winds from the WSW through South to ENE. The harbours both lie in the Republic of Ireland.

Although there was activity here to support the original “Green castle” built in Norman times the first pier was not constructed until the early 19thC. This has been expanded over the years and today it contains the terminal for the Magilligan Ferry and also services the Port of Londonderry Pilots.

Moville is 2nm further SW along the coast from Greencastle and, of the two, probably has more in the way of amenities in the town though the shelter is not so good. It consists of a single pier on which most of the inside berths are taken by local fishing boats and the outside berths exposed to the tides and any weather from over the Lough.

Yachtsmen should take note that although there is an anchorage between here and Carrickarory Pier it is in the tideway which can make rowing ashore or back a protracted affair if your dinghy is not equipped with an outboard motor. ... read more


The approaches to Lough Foyle are dealt with in our article Lough Foyle, Londonderry Marina & Approaches

Until recently the entrance to Greencastle was delineated by a sector light on the NW harbour entrance but this has now been removed during the building of a new outer harbour. 

Unfortunately that improvement has been put on indefinite hold so that, at present, all that has been done is an incomplete breakwater to the SW of the harbour stretching about 150m out from the shore and has an ECM (VQ(3) 5s) at its outer end. The sector light has been replaced with a red lead in mark on the inner wall of the harbour with 2 Flashing Green vertical lights which may or may not be working.  ... read more

Berthing, Mooring & Anchoring

In the past the locals preferred visitors to anchor outside Greencastle harbour but this is no longer the case; visiting boats are catered for at the NE corner of the harbour but they may have to raft at busy times.

I'm afraid the situation here is still in flux; they are trying hard to get funding but so far not much luck. They got their funding for pontoons back in 2015 on the back of a couple of international events in Londonderry and since then nothing.
Update 2015

These notes were reviewed by Don in April 2015. The layout here is under constant change depending on funding. The end game is to extend the harbour from the existing south pier to the end of the breakwater at present marked by an ECM but the timing is uncertain.

We ran out of money last summer after re fueling to find that there is no hole in the wall cash machine in Green Castle
