Courtesy of a competition in my local rag I am off soon for a few days' sailing to Southern Ireland on the "Lord Nelson". The Jubilee Sailing Trust insists that I need a passport. I am sceptical. Whether it is Cork Week, the Liverpool-Dublin Sea Cat, cruising to Kinsale or a Fastnet-qualifier race to Howth, I have never carried a passport in the Irish Republic. Who is right? Has anyone ever been asked for their passport in the Emerald Isle?
