Limits of Dublin Port

Under the 1996 Harbours Act the limits of Dublin Port consist of the waters of the River Liffey commencing from and including Rory O'Moore Bridge and extending to an imaginary straight line drawn from the Baily Lighthouse on the north in the County of Dublin and extending through the North Burford Buoy and thence through the South Burford Buoy and thence to Sorrento Point on the south including all bays, creeks, harbours and all tidal docks within such area.


For information on anchoring positions please refer to the admiralty chart No. 1415.

Anchorage is position 53n 21, 6w 12,sand over stiff marl. This anchorage is very exposed and a vessel should be prepared to leave at the first sign of a
shift of Wind E.

Approach and Berthage

The approach to the harbour of Dublin is well lighted and of easy access. There is a channel across the Bar which is 7.8m below LAT. Vessels drawing up to 10.2m can enter the port at high water of normal tides. Vessels drawing up to 7m can enter at any state of tide. Vessels proceeding to the Dublin Bay Buoy, which is a Roundabout Buoy to be passed on the vessel's port side, should proceed through the Traffic Separation Scheme which was introduced during 1997. The scheme comprises of two elements, an inward lane and outward lane at North Burford and South Burford. For larger craft this is the only access to Dublin Port.

Mean H.W. Springs Dublin Bar 4.1m. Mean H.W. Neaps, 3.4m. Prevailing winds are S.W. All depths refer to the Lowest Astronomical Tide. This level is defined as "the lowest level which can be expected to occur under average meteorological conditions and under any combination of astronomical conditions."

This datum is referred to as L.A.T. and 2.51m below Ordnance Datum Malin Head.

Verification of Depths

All berth, channel and bar depths given hereunder are standard Lowest Astronomical Tide (L.A.T.) maintenance
depths which are liable to reduction through silting or other causes. Verification of depths in the port should, therefore, be obtained from the
