Caitriona Lucas was part of a three-person crew thrown into the sea when their boat capsized in difficult weather conditions during a search operation with the Irish Coast Guard.
The 41-year-old librarian with Clare County Council leaves behind a son, Ben (20), daughter Emma (18) and her husband Bernard, who is also a member of the Doolin Coast Guard unit.
Irish Coast Guard operations manager Gerard O'Flynn said she was an amazing colleague.
"She'll be hugely missed. She just wanted to serve their community and has such a proud record of (doing that)," he said.
Funeral mass will take place at Liscannor Church at 11am, with burial afterwards at Kilmacreehy cemetery.
