ISORA campaigners Andrew and Sam Hall retired from the RORC Transatlantic Race after his yacht Pata Negra lost a rudder with 900 miles to go in the 3,000-mile race.
According to Liverpool Yacht Club crew reports on social media, the Lombard 46 was running downwind in the middle of the night when the damage occurred.
"Lost port Rudder, crew all OK, making way to harbour" is the official report on the race website.
There was some sail damage in the incident, too, but all are reported safe and well on board.
The crew say they are 'devastated' at not being able to finish the race, according to information received by ISORA's Peter Ryan.
The latest update from onboard says, "They have managed to bung the hole to stop the water coming in and are now nursing the boat under jib to the nearest land, 5-6 days away."
As Afloat reported earlier, Dublin Bay's Conor Corson is Pata Negra's Watch Captain.
