Cornashamma Bay

Tides and tools
Overview





Cornashamma Bay is located on the north coast of Ireland a mile to the southwest of Inishowen Lighthouse on the eastern side of the Inishowen Peninsula. It offers an anchorage within a protected rock fringed inlet set into the coast.

Cornashamma Bay is located on the north coast of Ireland a mile to the southwest of Inishowen Lighthouse on the eastern side of the Inishowen Peninsula. It offers an anchorage within a protected rock fringed inlet set into the coast.

The anchorage lies under the lee of the peninsula and affords good protection in winds from south-southwest through north to north-northeast, but is exposed to easterly winds from east to south. Due to offlying rocks on either side of the bay, it requires attentive navigation in daylight, and although tidal streams are strong outside, Cornashamma Bay is accessible at all states of the tide.
Please note

Good visibility is required to circumnavigate a sunken rock in the entrance path. Vessels operating in the Lough Foyle area should maintain a listening watch on the primary Foyle VHF Channel 14.

How to get in?


Cornashamma Bay is rocky bight set into the Inishowen Peninsula close outside the entrance to Lough Foyle and a mile to the southwest of Dunagree Point that is made conspicuous by its lighthouse.

Convergance Point Set just off the entrance channel to Lough Foyle, approaches to the area are detailed in the Foyle Port Marina (Derry City) Click to view haven entry.

Steer to approach Cornashamma Bay’s south western corner from the east. The inlet is fringed by exposed rocky reefs extending on either side about 100 metres apart. The rocks continue north-eastward from the shoreline with the northern side continuing foul underwater.

The key rock to observe is in the middle of the entrance. It is an unnamed rock with 1.2 metres of water over it at LWS. It should be clearly visible against the white sands of the bay’s floor.


Haven location Once past this covered rock, anchor according to draft in sand that provides very good holding. Land by tender on the beach.


Why visit here?
Cornashamma Bay, known locally as "Sweet Nellie", is a secluded beach and another anchoring opportunity along the eastern Inishowen shoreline.

Silver Strand, White Bay and Portnocker also provide access to this coastline but Cornashamma Bay offers the best protection of the anchorages outside of the lough. This makes it a useful passage anchorage for boats en route east or awaiting a tide to enter Lough Foyle.


What facilities are available?
Cornashamma Bay has no facilities and the nearest supplies can be found in the separately covered fishing village of Greencastle Click to view haven or the small town of Moville Click to view haven. An alternative is the small village of Stroove a few miles north of the village of Greencastle off the R238.


Any security concerns?
Never an issue known to have occurred to a vessel anchored at Cornashamma Bay.
