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 don’t 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.

I reviewed these notes in August 2022. I've completely edited these notes to take in the pontoons at the Southern pontoon. (I'd been adding bits and pieces but have now collated the lot together to make sense.) I have reservations about the shelter on the pontoons as they look very open to weather coming through the Straights from the NE and East.

Update Summer 2019
Written by Don Thomson 3 | 2nd Sep 2019
I visited here this summer. The pontoons on the new South wave barrier are fine, well anchored in and have all the usual services (if a bit basic see new photo!). Absolutely no room inside the old fishing harbour at Greencastle.
Update Spring 2019
Written by Don Thomson 3 | 13th May 2019
I reviewed these notes in May 2019. It s difficult to contact the HM of this harbour and we are not sure as to the suitability of the suspected pontoons at the South wall.

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
Written by dononshytalk | 10th Apr 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.
Cash Machine

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
