Strangford Narrows, Strangford Harbour and Portaferry

This article deals specifically with the tricky entrance to and exit from Strangford Lough, plus facilities available just within the entrance at Portaferry and Strangford. The interior of Strangford Lough and the cruising delights within are dealt with in another article to be found HERE (opens in a new tab)

With tidal flows in the entrance reaching speeds of up to 7.5 Knts at springs, the windows for departure and entry are small. The period of slack water is only around 15 mins, so for the stranger, entry is limited to an approach in daylight, at around the turn of the tide. Do not approach in strong (above F4) onshore winds as breaking seas can extend well over a mile SE of the entrance. Even in much calmer conditions standing waves may be encountered, see the video in the "Approach" section.

Once within the lough, there are untold sheltered anchoring and mooring opportunities, including the small marina at Portaferry near the entrance.

The sea lough itself covers 150 sq km, the largest in the British Isles. The narrows open out into gentler waters with 70 islands. Countless tidal rocky outcrops called pladdies (some visible and many just under the surface) litter the lough and mudflats, along with marshes, rocks, bays and headlands. The lough is a conservation area and its abundant wildlife recognised internationally for its importance.


The Lough itself offers a self-contained cruising area in it's own right, and further detailed coverage of the interior is now here

Approach

Timing is everything when dealing with the entrance to Strangford Lough, and you will need a decent chart of the entrance showing the transits. Exit needs special care as with the ebb tide under you there will be a point of no return, where the mariner will have no option but to face possibly rough water, standing waves and overfalls.


Leaving Strangford Lough:




Adrian Coughlan:

"There is quite an ebb there OK. We scooted down the lough (following our friend in a heavy Fisher 37 with full sail up). When we got to the entrance there was a fairly bumpy ride - the overfalls are quite disconcerting sight for the uninitiated as we approached it at around 10 knots over the ground. I was amazed at the pounding the Fisher took ahead as he bashed into the standing waves, and for a split second or two thought of making a run south for the inside of St Patricks rock which did look relatively calm (after clearing Angus Rock first). However, I think we would have ended up going sideways and wouldnt have made it - possibly would have ended up on the rock. So, we just went through the overfalls and bobbed out the other side. Quite a bumpy ride for a small boat even in those conditions - very exhilirating at 7am in the morning !.."

Rules & Regs

Hazards

Very strong tidal flows (up to 8knts), cross sets, uneven bottom raises rough seas, assorted rocks. Ebb against wind can produce dangerous seas up to 1 mile off. Once in watch out for the ferry, danger of being set down on it.

Tides

Narrows: Ingoing stream starts HW Belfast -0330, outgoing stream starts HW Belfast +0230. 15 min slack period at turn of tide.

  Berthing

There are two available stop off points as one transits the narrows which, as we have said, is best done at slack tide or early in the flood. Considerable care must be taken when turning into either of these when the tide is running or you run the risk of being swept past on the tide.

Strangford Harbour on the SW side of the narrows is mainly for the ferry that crossed to Portaferry, but there are anchoring opportunities out of the tidal flow, a couple of moorings provided by a local pub, and the chance of coming alongside the New Quay for short periods.

There is a new pontoon here built on to the North side of the pier which can take quite a few boats. Call at the Cuan Restaurant to pay dues and get the access code for the pontoon. Their telephone number is 028 4488 1222

Portaferry (NE side) offers a small marina with up to 50 visitors berths with depths of up to 2.5m. Normal marina facilities, inc. pontoon berths, water and electricity. There are also a couple of visitors moorings, again provided by a local hotel. If berthing here you need to be aware of the tide which pushes through here at quite a rate; you will have come in on the flood so will need to turn round to face into it to berth - it may even be too strong to back into.

The marina charges (2021 are now £23 for up to 8 mtres and £25 for a 10metre boat staying overnight.

Update September 23
06 Sep 2023 by Stephen Torrance
Beautiful area £21 for our 8m yacht at Strangford. Fees paid at Cuan Hotel where a shower is available for £5. Have to say the shower was an absolute disgrace and unexpected in such a nice hotel. Hopefully they will sort it out. Strangford is beautiful and entry is ok in the right conditions.

Entering Portaferry Marina
04 Jul 2015 by Taff
The flood flows strongly into the Marina. If you enter with it, be sure you can either stop at the pontoons facing you, or else go around the end of the finger, and turn into the tide to berth. Some might reverse in. We entered at slack the first time, and against the ebb afterwards. Helpful staff and a lovely area.

NEW PONTOON IN STRANGFORD HARBOUR
03 Jun 2014 by cuillin
There is a relatively new, and substantial, Pontoon built on to the north side of Strangford Quay to facilitate visiting boats. A lovely location. It can accomodate a number of boats (I estimate it about 80ft long). Just follow the sailing directions to the Quay, and you will spot it easily. Fee to be paid at Cuan Restaurant. and access code given there. The pontoon can be seen in the Overhead view of the Narrows, on this site.

TIDAL FLOW INSIDE PORTAFERRY MARINA
03 Jun 2014 by cuillin
Visitors should be aware that the tide in The Narrows can flow quite strongly through the Marina, under the pontoons. This should be taken into account when berthing and deciding whether to berth port or starboard side-to. The tide can quickly push the bow away when coming into the pontoon - so be aware!
