The full lineup of 18 teams will be ready to battle in Dun Laoghaire Harbour this weekend for the sixth Elmo Trophy.
This youth sailing team racing event will see teams of six sailors representing their clubs or classes race in the 18 Firefly dinghies that are supplied for the event.
The 108 competing sailors at the Royal St George Yacht Club are aged between 13 and 19 with a 50:50 split between boys and girls.
The team travelling the furthest is a first-time entry from Glandore Yacht Club skippered by Conor Cresswell, while one of the host teams will include a member of Liverpool's West Kirby Sailing Club.
On paper, very strong lineups are entered from Royal Cork skippered by Lola Kohl, National Yacht Club skippered by Natasha Hemeryck, the 29er class skippered by Trevor Bolger and the Waszp class skippered by Max Goodbody.
A host team skippered by Finn Walker will look to defend the trophy won last time by 'Curious George' in 2019.
Over 130 races are expected to be sailed with the final scheduled for Sunday afternoon.
