A search is underway after a small fishing vessel sank off the Dublin coast.
Two people were on board at the time.
One crewman has been found.
The Marine Rescue Coordination Centre say the recovered crewman was brought ashore.
He was handed over the HSE ambulance service and brought to hospital for medical treatment.
A search is continuing for the second crew member.
Owen Medland, Area Lifesaving Manager at RNLI, explained: "There's an ongoing search effort involving the LÉ Orla, the RNLI assets from Howth and Skerries, and a number of local fishing boats."
A Coast Guard helicopter is also assisting with the operation.
