More than 80,000 euro has been raised in two days to support the search for two fishermen missing at sea for a week.
The donations will pay for fuel for trawlers out searching for the bodies of newlywed Ronan Browne and David Gilsenan.
The friends vanished last Friday when fishing for lobster off Skerries, north Dublin.
Skerries Chamber of Commerce said 6,000 euro has been donated in fuel, with almost 75,000 raised at a coffee day and a charity walk of solidarity.
Businessmen Martin Scully and Ollie Grimes, who organised the events, said everyone should be proud of the way people have rallied in such an extraordinary and inspiring way.
"The families of Ronan and David would also at this time like to express their sincere thanks for the warmth, strength and support offered from everyone concerned as the search effort continues," they added.
The navy is co-ordinating the major operation to retrieve 26-year-old Mr Browne, from Skerries, and Mr Gilsenan, a 41-year-old father of two who lives in Rush.
Scores of pleasure and fishing craft and diving clubs from across the country are expected to join coast guard and RNLI crews along the east coast on Saturday and Sunday.
A bank account which has been opened at the Bank of Ireland branch in the town in the name of Lady Linda - the name of the boat the men were fishing from.
Schools, shops and people in coastal communities across north Dublin are also staging fundraising events.
