Ireland is an island nation but not yet a maritime nation. So said Capt. James Robinson of the Irish Maritime Forum and formerly of the Irish Naval Service when opening the Forum's conference at the National Maritime College in Ringaskiddy, Cork Harbour, this morning. Attendance at the one-day conference 'Maritime Aspects of the 1916 Rebellion' has been fully booked-out. It is examining the influence of sea power on the rebellion, including the Aud and the Helga. People are attending from all over the country.
