Dublin's Lord Mayor Gerry Breen will assume the traditional title of Admiral of the Port of Dublin when he presides over the Parade of Sail on the Liffey later this month.
The parade on Sunday 29 May is a highlight of the annual Dublin Bay Old Gaffers Association rally, which this year is held in tandem with the Stella Maris Rowing Club regatta.
Rowing clubs along the east coast will be sending crews to Dublin to compete for the special Asgard Trophy, which is made of timber used in the conservation of the original Asgard in the National Museum.
The event - centred at the Poolbeg Yacht and Boat Club near Ringsend - is also expected to attract classic vessels from ports in Wales and Northern Ireland.
The Old Gaffers Association is a sailing organisation dedicated to preserving traditional sailing craft, usually former working boats, and mainly of wooden construction, promoting their distinctive gaff rig.
