Port Dandy on Copeland Island, the principal of the Copeland Islands group, is located in the Irish Sea off the northeast coast of Ireland. The island group is situated on the south side of the entrance to Belfast Lough and Copeland Island is the largest island and closest to the mainland. Port Dandy is a very small inlet on the west side of the secluded island where a vessel may anchorage for a maximum of two or three boats.

The bay provides good anchorage in the north through east to southerly conditions, but is exposed to all conditions with a westerly component and holding is not the best. Access is straightforward in daylight at any stage of the tide although a great measure of tidal planning will be required to operate in this area.

Any trip to the Copeland Islands will require good charts and careful navigation as the waters are shoal, encumbered with rocks and the channels between are swept by rapid tides. This is particularly true of Donaghadee Sound, where streams achieve 4.5 knots in places and great care plus tidal planning is necessary on approach and departure. In thick weather, the area should be avoided entirely.

What's the story here?

Copeland Island is by far the largest of the group of three islands, Lighthouse Island and Mew Island being the others, that mark the southern entrance to Belfast Lough. It is nearly 1 mile long, a ⅓ of a mile wide and it is low only rising to a modest 31 metres at its highest point. It forms the eastern side of Donaghadee Sound and Port Dandy is a narrow west-facing bay located close south of the western extremity of the island. The island is privately owned, with residents who come to stay during the summertime. Tourist boats bring visitors from Donaghadee who land at the jetty in the opposite Chapel Bay.

Port Dandy is a very small inlet that provides a popular anchorage for a maximum of two or three boats with a beach to land.

How to get in?

Use the details available in the northeast Ireland’s Coastal Overview for Malin Head to Strangford Lough for local approaches and the Donaghadee Sound for local tidal optimisations. The bay is clear from all approaches with one single exception for vessels approaching from the opposite Chapel Bay, around its western arm, or cutting in from Donaghadee Sound. A vessel approaching Port Dandy from these directions will have the very dangerous and awash Rid Rock in the pathway.




This is a detached termination of a reef off the drying area that extends a ¼ of a mile southward from Copeland Island's southwesternmost point. This visually terminates at the continually exposed 1 metre-high islet of Carn Point but foul ground then extends a further 200 metres south by southeastward from Carn Point to the dangerous Rid Rock.

Rid Rock - Awash detached rock position: 54° 40.130' N 005° 32.590' W




So it is essential not be tempted to follow the southwestern coastline of Copeland Island from Chapel Bay into port Dandy. Rather it is necessary to drop south of Chapel Bay, and then circle south around Rid Rock, before approaching Port Dandy from the west. Rid Rock is positioned almost due west of the southeastern extreme of Copeland Island. So when it is on a bearing of 85°, or less, it is safe to proceed westward on that line, southward of Rid Rock, until Carn Point is aft of the beam, before turning northward.

Vessels approaching from all other directions may cut in closer as there are no dangers 150 metres out from the western shoreline of Copeland Island.


From the Port Dandy Initial Fix sound in due east to approach the inlet that is just over 300 metres away. Be vigilant not to be pushed off course by the tidal streams of Donaghadee Sound. Port Dandy’s sheltered waters lie close inside the small and narrow slot.



Come right into the centre of the slot where enough space will be found to accommodate at least a couple of boats. The inlet is steep-too with good water close in. Anchor according to draught over a bottom of rock and stones where holding is not great.




Dinghy landings are possible on the rocky beach at the head of the inlet. Copeland Island is owned by Alan and Ryan McCulla and access to the island beyond is only by direct permission from the owners.

Why visit here?

Port Dandy is an alternative anchorage to Copeland Island’s more spacious primary anchorage situated in the adjacent Chapel Bay. Small and enclosed it is very different to Chapel Bay and very popular during the sailing season. Doubtlessly that is how it got its name with 'Port' literally meaning port and 'Dandy' meaning 'an excellent thing of its kind'. Further information is available for the island in the Chapel Bay entry.

From a boating point of view, akin to Chapel Bay, is a very useful anchorage on the southern entrance to Belfast Lough. It provides easy access and perfect shelter in easterly conditions where it offers a useful tide-wait anchorage for those heading along the coast or up towards the North Channel without the time it takes to set down in a harbour or marina or indeed take a detour into Belfast Lough.

What facilities are available?

There are no facilities available off this secluded island.

Any security concerns?

Never an incident known to have happened to a vessel anchored in Port Dandy.
