Located off Ireland’s southwest corner, Sherkin Island creates the natural Baltimore Harbour that lies between it and Spanish, Ringarogy Islands as well as the mainland. This berth is off the island's old castle within Baltimore Harbour and it provides an anchorage and a seasonal pontoon.

Set in the lee of the island this location provides complete protection and is especially good in strong westerly component winds. Winds from southeast round to southwest, however, can cause a groundswell that increases in rough weather. The harbour offers safe access at all tides, night or day in all reasonable weather conditions, via its well-marked primary and preferred southern entrance. Baltimore Harbour may also be reached from the northwest by coming in around Hare Island and north of Sherkin Island via The Sound. Although more than workable, this requires careful pilotage between islands and rocks.

Castle Ruins directly within the entrance to Baltimore Harbour Image: Michael Harpur
Sherkin Island forms the western boundary of the expansive Baltimore Harbour and is separated from Clear Island by Gascanane Sound, to which it is similar but not so high. 3 miles long and 1 mile wide it is one of the largest islands of Roaringwater Bay and it forms the southeastern boundary of Long Island Bay. Castle Ruins lies off of the Sherkin shore, directly within and opposite the entrance. The anchorage lies off the ivy-clad remains of a medieval fort set upon a rock that appears nowadays more an outbuilding the Islander’s Rest Hotel that stands close above it.
The pontoon with Baltimore Harbour in the backdrop Image: Graham Rabbits
An anchorage is available here in from 3 to 5 metres of water, on mud and sand with excellent holding. It provides a very good Baltimore Harbour berth during strong westerly winds. There is also the option to berth alongside on the seasonal Sherkin Island Marina a pontoon that belongs to nearby Islander’s Rest Hotel. The pontoon is available from mid-April to mid-September (weather permitting) and it can cater for up to 10 yachts when rafted in 2.4m LAT. Rates per night vary from €15.00 to €40.00 (depending on size) and enquires can be made to Islander’s Rest Hotel +353 (0)28 20116.

Use Ireland’s coastal overview for Cork Harbour to Mizen Head for seaward approaches and the Baltimore directions for local approaches to the southern entry. An approach can also be made from Long Island Bay through The Sound, between the islets and rocks at the head of the bay with details available in Baltimore Harbour North Entrance .
The entrance to Baltimore Harbour as seen from the south Image: Michael Harpur
The primary entrance to Baltimore Habour is its southern entrance between Beacon Point to the east, marked by a beacon, and Barrack Point on Sherkin Island, marked by a lighthouse. Proceed through the centre of the entrance continuing north to leave the Loo Rock marker, a starboard Light Buoy Fl.G.3s, on the eastern side of the entrance, to starboard. The rock is located in a north-easterly direction from the buoy, nearly one-fourth of the distance across from the eastern to the western points, and uncovers at low water spring tides.
Loo Rock – starboard buoy Fl G 3s position: 51° 28.438'N, 009° 23.458'W
Abbey Strand to Castle Ruins (with the pontoon removed) Image: Michael Harpur
From the Loo Rock, Starboard marker follow the Sherkin shoreline in depths of 6 metres of water. Within the entrance, the conspicuous ruin of an abbey will be seen on Sherkin Island with a road leading down to the quay to Abbey Strand where the island ferry docks.
A good lookout should be maintained for the ferry that crosses from Baltimore to Abbey Strand. This crosses every hour in summer and every two hours in winter so it may cross your path on entry.

Berth alongside on the 'Sherkin Island Marina' pontoon or anchor in 3 to 4 metres of water on mud and sand off of it.
Do not anchor between Tramadroum and Abbey Strand, half a mile west-southwest on Sherkin Island to avoid the telegraph cable. There is another cable 200 metres further north by northwest as best seen on a chart.

Why visit here?
Sherkin Island has gone by many names. A 1620 map of Baltimore gives it the name 'Inisherkin Island' and Petty’s Survey Map of 1658 refers to 'Inisherkin'. By the 1821 census it was referred to by its modern name 'Sherkin Island also called Innisherkin'. All of the names are derived from the Irish 'Inis Arcáin' meaning 'island of the piglet'. But the piglet referred to here are 'sea-pigs' which were what 'porpoises' were called, a group of fully aquatic marine mammals, similar in appearance to a dolphin.
The ivy clad ruins of the O'Driscoll Castle overlooking the pontoon Image: Tiago Mendes-Costa via CC BY-SA 3.0
One of Carbery’s Hundred Isles, there is evidence of human occupation going back thousands of years as by its standing stones, megalithic tomb and ring fort. In the Middle Ages, The O’Driscoll’s owned Baltimore, Sherkin, Cape Clear, and much of West Cork. It is they that built the ruined Dunalong Castle, from Irish Dún na Long meaning 'Fort of the ships' in the early 1400s. This is the ivy-clad remains on the rock that overlooks the anchorage today and it would remain the seat of the clan. It was Dermot O'Driscol who invited the Franciscans in 1449 to build the friary Mainster Inis Arcain, known locally as the Abbey, that stands in ruin above Abbey strand. But the more nefarious activities of the O'Driscol's would also bring destruction to the island.
In retaliation for a 1537 act of piracy on a Spanish vessel consigned to Waterford port by Fineen O'Driscol and his son, the citizens Waterford fitted out and armed three ships and mustering 400 men to arms. They sailed into Baltimore Harbour and anchored off under the castle. The garrison fled and the Waterford men quickly took over the castle and kept possession of it for five days. During this time, they ravaged the island, destroy all the villages, the Franciscan monastery and eventually the castle itself. Having laid waste to Sherkin they then landed at Baltimore and set fire to the castle and town. Finally, having seized O'Driscol's chief galley and a great number of other small boats, they returned in triumph to Waterford.

The castle was subsequently rebuilt and the clan’s last chief, Sir Fineen O'Driscoll, the Rover, was to be the most notorious of the clan. In the first period of his reign, he supported the English rulers by confiscating Spanish ships and was so effective that he was knighted for his efforts in 1587. But when West Cork was to see the climax of the Nine Years' War he changed sides and joined Hugh O'Neill, Hugh Roe O'Donnell and other Irish lords against the English rule of Tudor Queen Elizabeth I. The Irish were supported by an invading Spanish force and Fineen O’Driscoll allowed the Spanish soldiers to garrison his castles. After the devastating defeat of the Irish forces, at the 1601 Battle of Kinsale, the property of the O’Driscolls was confiscated and given to Lord Castlehaven.

Most of the O'Driscolls emigrated to Spain in its aftermath, leaving behind their followers and dependents, who gradually became mixed with the local population. Despite his actions, Sir Fineen managed to secure a pardon from Elizabeth I. He eventually died lonely and destitute in 1629, after retiring to the castle in Lough Hyne. The local islander continued without their old Gaelic lord and the island attained a population of around a thousand in the early 1800s. This population was to precipitously decline and never recover during the middle of the century due to the Great Famine.

Today the island has a permanent population of about 100 which increases greatly during the summer months as Sherkin is a very popular tourist destination. Many of the local residents are active in the fields of art and culture, island crafts, painting, book writing and of course music. The small community has a primary school, two pubs, a hotel, guest house B&B, a community centre and a R.C. Church and that’s about it. The roads on the island are in such a poor state that most residents prefer to cycle or walk, although there is a rural bus service that meets every ferry.
Those who do brave the roads will find the island has stunning secluded beaches the best of which face Long Island Bay, with swimming areas ideal for children at Silver Strand, Cow Strand or Trabawn, which should not be missed. The best place for barbeques is Silver Strand where there is a choice of soft grass or warm sand to sit on. Those who do picnic should make sure all litter is removed as Sherkin has no disposal facilities and they are proud of their title as being one of Ireland’s cleanest islands. A key sailing event is the Sherkin Regatta that is usually held on the third weekend in July. This is the islands busiest day of the year when it is crowded with sea rowers and much more, including children’s activities, and music and food stalls all contributing their part to this Sherkin fair.

From a boating point of view, the anchorage in the lea of Sherkin Island is the place to come when Baltimore Harbour is subject to developed westerlies. Like any other coastal part of Ireland, Sherkin can be affected by heavy coastal gales, but it and the harbour area as a whole is also the perfect 'hurricane hole' to take refuge from foul weather. But don’t make the abode of strong winds as the island is a must-visit location for any yachtsman cruising in this area and best enjoyed during fine weather. It has its own special character, unspoilt charm, tranquil and breath-taking beauty all far removed from the hustle and bustle of life on the mainland. A place where renowned hospitality can be enjoyed, in a relaxed atmosphere, with residents and tourists alike, enjoying informal music sessions in either of the island pubs.
What facilities are available?
The Seahorse Marina provides water and electricity at the pontoon; food and refreshment 50 metres above at The Islander's Rest hotel. Please note the marina does not offer any waste collection. Sherkin Island has two good pubs and a restaurant. General stores are available across the harbour in Baltimore but may be limited. You can however catch a bus to take you to the larger provincial town of Skibbereen (approximately 10km) where a wider range of provisions are available.
Ferries sail from Baltimore to Schull further along the coast, to Sherkin Island, and to the more remote Cape Clear Island.
Any security concerns?
Never a security issue known to have occurred off Sherkin Island.

The Islanders Rest has been rebranded as Sherkin House. Little evidence in June of much activity and lots of Private property signs. Planning applicants for new dwellings - all changed! Still a lovely anchorage in anything but southerly winds with great walks ashore.
