An event to mark the 80th anniversary of the Cork Harbour tragedy is underway.
Five soldiers died when two launch boats collided with the vessel "Irish Poplar" in 1942.
The L.E William Butler Yeats is leaving Cobh in the next few minutes with family members of those who lost their lives on board.
Members of the Port of Cork, the Irish Naval Service and local fishermen will follow the ship to the scene of the tragedy.
A memorial mass will take place tomorrow at St Coleman's Cathedral in Cobh tomorrow and the group will parade to the monument at East Beach in the town for a wreath-laying ceremony.
