The Irish Sea is a huge, almost landlocked sea. Around its shores and islands there are no fewer than six countries, provinces or protectorates. Several languages are represented; English, Welsh, Irish, Scots Gaelic and Manx, along with countless accents and dialects. Its waters teem with life; dolphins and porpoises are a common sight; leatherback turtles come here from the Caribbean to feed on the jellyfish and whales are regular visitors. In the air there are gulls, puffins, guillemots and more. The range of challenges and coastlines is astonishing. Tides above five knots are commonplace and yet there are calm, sheltered waters for relaxed wandering. This well established pilot covers both sides of the Irish Sea from Milford Haven to Portpatrick, and Rathlin Island to Carnsore Point. From his base in Liverpool David Rainsbury spent much of 2014 revisiting the coasts he describes. The sailing directions and descriptions, updated for this second edition, cover all the places that provide shelter. At the start of each chapter there are useful coasting notes which deal with some of the more difficult passages and tidal gateways. The harbour text is then clearly organised so that essential information regarding accessibility, tides and shelter always proceed the pilotage notes which are supported by clear full colour plans. For this second edition the harbour plans have been updated and throughout new photos have been added. The text records all changes as well as including a new section on wind farms. Updates are published on the Irish Sea Pilot website.
