I reviewed these notes at the end of August 2022. Firstly many thanks to Camper below for his comprehensive notes below. The pontoon he advised as lifted is back in the water now. otherwise little has changed.

I spent last weekend in and around the Lough. It’s worth a detour, very pretty, good facilities overall.
First, the less welcoming end of the spectrum, Warrenpoint harbour. A busy container port, with narrow shipping channel, which possibly explains the lack of effort, perhaps welcome, for visiting yachts. Don’t expect a visitors berth to me made available in the town dock, although there should be one there and there is usually space. It comes across as a poorly managed facility, perhaps an indication of their focus on the big ships. There is a visiting berth on the outer pontoon, which even if occupied should be ok for berthing alongside. See diagram I will upload.
Currently there are no other pontoons in Warrenpoint. The one on the breakwater has been lifted. The one on the entrance to the harbour is rickety and does not look safe. The Town docks charge £25 a night, for a berth and no other facilities- electric cables too far away and no toilets within reasonable distance. Which is why, on balance, I’d rather anchor at the Woodhouse.
The Woodhouse between Rostrevor and Killowen is a lovely anchorage, good shelter from east and north, ok from south. Good holding in mud. Currently there are two long term anchorage’s boats there, both occupied, the locals tell me for months. It’s a good site. There’s a swimming quay to land at, about 600m from the anchorage. The town is pretty and welcoming.
Carlingford marina is useful, as described elsewhere. Handy to town and to revictual. Carlingford is another pretty little town.

I reviewed these notes in July 2021. We've obtained copies of the 2021 documentation for the Ship Canal and updated the info on Warrenpoint Town Dock. Eventually there will be a new ring road around Newry involving bridging of the Canal; the form of this bridging is yet to be finalised and they haven't started building the road yet.

These notes were updated in April 2017. Warrenpoint is still not very interested in visiting yachts. I've changed the price for Newry and also uploaded new charts.

These notes were reviewed by Don in April 2015. I'm afraid that work on the much hoped for marina has not yet started so the Town Dock is still the only overnight berthing

I reviewed these notes on 12 December 2013. The situation for visiting yachts has not changed and their marina is still on hold for better times. It is still possible to moor on the pontoons in the Town Dock where there are normally a couple of visitors berths
