Peel Commissioners are to mark the centenary of the sinking of the Lusitania off the Irish coast on May 7, 1915.
The first vessel attending the scene was the lugger The Wanderer, which was a Peel-registered fishing boat. She rescued 160 men, women and children.
The Lusitania, a liner sailing from New York to Liverpool, was torpedoed and sunk by a German U-boat off the southern Irish coast. A total of 1,198 died.
The killing of civilians shifted American public opinion against Germany during the war.
On Sunday, May 3, 2015, a flotilla of craft will set sail from Peel and a ceremony of dedication and remembrance will take place at sea just off Peel Castle when wreaths will be dropped in to the sea.
A celebration of life will take place that evening in a marquee erected at the former swimming pool site, Marine Parade.
The commissioners are still planning the event and are looking for ideas.
