The Lough Swilly RNLI volunteer crew were tasked to come to the aid of an injured fisherman on Wednesday morning.
The alarm was raised at 11.51am by the Malin Head Coast Guard nearly 35 nautical miles off Malin Head.
Recue 118 and RNLI Islay were also tasked to attend the scene.
The casualty was winched on board Rescue 118 and brought to Letterkenny University Hospital for treatment.
The All Weather Lifeboat returned to Buncrana Pier to refuel and make ready for service.
The RNLI has issued a reminder that if you’re in difficulty in or on the water or see someone in trouble, dial 999 or 112 and ask for the Coast Guard.
