The RNLI lifeboat station in Dun Laoghaire is holding it's traditional ceremony at midday at a memorial stone close to the station.
The 15 volunteers lost their lives when their lifeboat capsized while attempting to rescue those on board the SS Palme that ran aground off Blackrock in Co. Dublin.
Those who also lost their lives this year while serving with the RNLI will also be remembered.
