Ten people have been rescued from the sea in two separate incidents off the coasts of Dublin and Waterford.

Four people were rescued off the Waterford coast after their fishing boat capsized this afternoon.

The four were fishing in Tramore Bay when their vessel was hit by a large wave shortly after 1.30pm.

The 19-foot vessel overturned, but all four men were wearing lifejackets and they managed to alert the coastguard.

The RNLI crew from Tramore responded and brought three of the men aboard, while the fourth man had managed to swim ashore.

Three of the four men were brought to hospital for suspected hypothermia but their condition is understood to be not serious.

Rescue 117 from Waterford airlifted one of the men ot hospital.

In a second incident, six people were rescued after their motor boat capsized in Dublin Bay last night.

The incident happened around 4km off the coast at around 8pm.

The six, who were wearing lifejackets, were suffering from hypothermia and were taken by lifeboat to Dún Laoghaire.

From there they were taken to Saint Vincent's Hospital for observation.

Howth and Dún Laoghaire RNLI lifeboats and a Coast Guard helicopter were involved in the operation.

Dún Laoghaire RNLI coxswain Mark McGibney said it was fortunate that the six had been wearing lifejackets.

"These people were extremely lucky. Their small open motorboat had capsized and was upturned in the water," he said.

"All six were nearby or clinging to the upturned hull when the lifeboats arrived. They were extremely cold and needed medical assistance.

"Their lifejackets undoubtedly played an important role in their safe recovery," said Mr McGibney.
