The yachtsman reported missing after his untended vessel was spotted off Ards Friary at Sheephaven Bay is from Rathmullan, and not Buncrana as previously reported.
Searches were continuing yesterday on land and sea for the missing man, whose vessel Wood Magic spent several days moored in Sheephaven Bay before his family raised the alarm.
The single man is in his 50s and is a native of The Haw, between Rathmullan and Ramelton.
He left the Lough Swilly marina at Fahan on 14 June, and his family raised the alarm when he did not return as expected by Saturday 28 June.
Gardaí boarded the vessel and found no trace of the man.
